Create an Animated Side Navigation

Step 1) Add HTML:

Example

<div id="mySidenav" class="sidenav">
<a href="javascript:void(0)" class="closebtn" onclick="closeNav()">×</a>
<a href="#">About</a>
<a href="#">Services</a>
<a href="#">Clients</a>
<a href="#">Contact</a>
</div>


<span onclick="openNav()">open</span>


<div id="main">
...
</div>

Step 2) Add CSS:

Example

/* The side navigation menu */
.sidenav {
  height: 100%; /* 100% Full-height */
  width: 0; /* 0 width - change this with JavaScript */
  position: fixed; /* Stay in place */
  z-index: 1; /* Stay on top */
  top: 0; /* Stay at the top */
  left: 0;
  background-color: #111; /* Black*/
  overflow-x: hidden; /* Disable horizontal scroll */
padding-top: 60px; /* Place content 60px from the top */
  transition: 0.5s; /* 0.5 second transition effect to slide in the sidenav */
}

/* The navigation menu links */
.sidenav a {
padding: 8px 8px 8px 32px;
text-decoration: none;
font-size: 25px;
color: #818181;
display: block;
transition: 0.3s;
}

/* When you mouse over the navigation links, change their color */
.sidenav a:hover {
  color: #f1f1f1;
}

/* Position and style the close button (top right corner) */
.sidenav .closebtn {
position: absolute;
top: 0;
right: 25px;
font-size: 36px;
margin-left: 50px;
}

/* Style page content - use this if you want to push the page content to the right when you open the side navigation */
#main {
transition: margin-left .5s;
padding: 20px;
}

/* On smaller screens, where height is less than 450px, change the style of the sidenav (less padding and a smaller font size) */
@media screen and (max-height: 450px) {
.sidenav {padding-top: 15px;}
.sidenav a {font-size: 18px;}
}

Step 3) Add JavaScript:

The example below slides in the side navigation, and makes it 250px wide:

Sidenav Overlay Example

/* Set the width of the side navigation to 250px */
function openNav() {
document.getElementById("mySidenav").style.width = "250px";
}

/* Set the width of the side navigation to 0 */
function closeNav() {
document.getElementById("mySidenav").style.width = "0";
}

The example below slides in the side navigation, and pushes the page content to the right (the value used to set the width of the sidenav is also used to set the left margin of the "page content"):

Sidenav Push Content

/* Set the width of the side navigation to 250px and the left margin of the page content to 250px */
function openNav() {
document.getElementById("mySidenav").style.width = "250px";
document.getElementById("main").style.marginLeft = "250px";
}

/* Set the width of the side navigation to 0 and the left margin of the page content to 0 */
function closeNav() {
document.getElementById("mySidenav").style.width = "0";
document.getElementById("main").style.marginLeft = "0";
}

The example below also slides in the side navigation, and pushes the page content to the right, only this time, we add a black background color with a 40% opacity to the body element, to "highlight" the side navigation:

Sidenav Push Content w/ opacity

/* Set the width of the side navigation to 250px and the left margin of the page content to 250px and add a black background color to body */
function openNav() {
  document.getElementById("mySidenav").style.width = "250px";
  document.getElementById("main").style.marginLeft = "250px";
  document.body.style.backgroundColor = "rgba(0,0,0,0.4)";
}

/* Set the width of the side navigation to 0 and the left margin of the page content to 0, and the background color of body to white */
function closeNav() {
document.getElementById("mySidenav").style.width = "0";
document.getElementById("main").style.marginLeft = "0";
  document.body.style.backgroundColor = "white";
}

The example below slides in the side navigation from the left and covers the whole page (100% width):

Sidenav Full-width:

/* Open the sidenav */
function openNav() {
document.getElementById("mySidenav").style.width = "100%";
}

/* Close/hide the sidenav */
function closeNav() {
document.getElementById("mySidenav").style.width = "0";
}

The example below opens and close the side navigation menu without animations:

Sidenav without Animation

/* Open the sidenav */
function openNav() {
document.getElementById("mySidenav").style.display = "block";
}

/* Close/hide the sidenav */
function closeNav() {
document.getElementById("mySidenav").style.display = "none";
}

The example below shows how to create a right-sided navigation menu:

Right-sided navigation:

.sidenav {
right: 0;
}

The example below shows how to create a side navigation menu that is always shown (fixed):

Always show sidenav:

/* The sidenav */
.sidenav {
height: 100%;
width: 200px;
position: fixed;
z-index: 1;
top: 0;
left: 0;
background-color: #111;
overflow-x: hidden;
padding-top: 20px;
}

/* Page content */
.main {
margin-left: 200px; /* Same as the width of the sidenav */
}

How to Reset Forgotten Windows 10 / 8 / 7 Password,how to use pcunlocker,how to fix forgotten password in window 7/8/10 and...

Whether you are locked out of your own computer or need to help a friend or family member who forgot their Windows password, there could be times when you need to reset a lost Windows password. It’s quite easy to do if you have a bootable disk like PCUnlocker. This tutorial will walk you through the process of making a PCUnlocker Live CD, and booting your PC from CD to reset forgotten Windows 10 / 8 / 7 password easily.

Making Bootable PCUnlocker CD

The first thing to do is download the ZIP file for PCUnlocker using another PC you can access. Next, extract the contents of the ZIP file to a folder on your hard disk. Open the extracted folder in Windows Explorer, and you’ll see an ISO file named pcunlocker.iso that you need to burn to a CD (or USB).

reset windows password

To make a bootable CD (or USB drive) from that ISO file, I’ll be using the freeware ISO2Disc. Insert a blank CD and open up ISO2Disc, navigate to the ISO file in the unzipped files. Choose the “Burn to CD/DVD” option and click on Start Burn.

forgotten windows password reset

This will create a bootable PCUnlocker CD in minutes. Note: If you don’t have a blank CD around, you can make a bootable USB of PCUnlocker instead.

Boot Your PC from CD

Once you have a bootable PCUnlocker CD, insert it into the computer whose password you want to reset. As soon as you turn on the computer, press a system defined key (such as F12, ESC, DEL, F2) to access BIOS. Go to the BOOT menu and set CD/DVD as first boot option.

how to reset windows password

After you’ve changed the boot priority, save the BIOS settings and restart your PC. It should now boot into PCUnlocker CD.

Reset Forgotten Windows Password

When you’ve booted to CD, PCUnlocker will find the Windows operating systems that were installed on your hard drive. Select one of your user accounts in the list, and click on Reset Password button to proceed.

windows forgotten password reset

This will open the Change Password dialog, letting you enter a new password or leave it blank to remove password. If you’ve chosen a local account that was connected to a Microsoft account, you’ll get the warning that the program will convert your Microsoft account back to local user.

change forgotten windows password

Once you click OK, your Windows password will be reset immediately. Reboot your computer and reverse the changes you made to BIOS. You can then log back in to Windows with the new password!

How To Create a Login Form

Step 1) Add HTML:

Add an image inside a container and add inputs (with a matching label) for each field. Wrap a <form> element around them to process the input. You can learn more about how to process input in our PHP tutorial.

Example

<form action="action_page.php" method="post">
<div class="imgcontainer">
    <img src="img_avatar2.png" alt="Avatar" class="avatar">
</div>

<div class="container">
    <label for="uname"><b>Username</b></label>
    <input type="text" placeholder="Enter Username" name="uname" required>

    <label for="psw"><b>Password</b></label>
    <input type="password" placeholder="Enter Password" name="psw" required>

    <button type="submit">Login</button>
    <label>
      <input type="checkbox" checked="checked" name="remember"> Remember me
    </label>
</div>

<div class="container" style="background-color:#f1f1f1">
    <button type="button" class="cancelbtn">Cancel</button>
    <span class="psw">Forgot <a href="#">password?</a></span>
</div>
</form>

Step 2) Add CSS:

Example

/* Bordered form */
form {
border: 3px solid #f1f1f1;
}

/* Full-width inputs */
input[type=text], input[type=password] {
width: 100%;
padding: 12px 20px;
margin: 8px 0;
display: inline-block;
border: 1px solid #ccc;
box-sizing: border-box;
}

/* Set a style for all buttons */
button {
background-color: #4CAF50;
color: white;
padding: 14px 20px;
  margin: 8px 0;
border: none;
cursor: pointer;
width: 100%;
}

/* Add a hover effect for buttons */
button:hover {
  opacity: 0.8;
}

/* Extra style for the cancel button (red) */
.cancelbtn {
  width: auto;
  padding: 10px 18px;
  background-color: #f44336;
}

/* Center the avatar image inside this container */
.imgcontainer {
text-align: center;
margin: 24px 0 12px 0;
}

/* Avatar image */
img.avatar {
width: 40%;
border-radius: 50%;
}

/* Add padding to containers */
.container {
padding: 16px;
}

/* The "Forgot password" text */
span.psw {
float: right;
padding-top: 16px;
}

/* Change styles for span and cancel button on extra small screens */
@media screen and (max-width: 300px) {
span.psw {
    display: block;
    float: none;
  }
  .cancelbtn {
    width: 100%;
  }
}

what is Java Booleans,Boolean Expression,stepby step Java Booleans,EASY WAY TO LEARN Java Booleans,how to use Java Booleans

Java Boolean

Very often, in programming, you will need a data type that can only have one of two values, like:

YES / NO
ON / OFF
TRUE / FALSE

For this, Java has a boolean data type, which can take the values true or false.

Boolean Values

A boolean type is declared with the boolean keyword and can only take the values true or false:

Example

boolean isJavaFun = true;
boolean isFishTasty = false;
System.out.println(isJavaFun);     // Outputs true
System.out.println(isFishTasty);   // Outputs false

However, it is more common to return boolean values from boolean expressions, for conditional testing (see below).

Boolean Expression

A Boolean expression is a Java expression that returns a Boolean value: true or false.

You can use a comparison operator, such as the greater than (>) operator to find out if an expression (or a variable) is true:

Example

int x = 10;
int y = 9;
System.out.println(x > y); // returns true, because 10 is higher than 9

Or even easier:

Example

System.out.println(10 > 9); // returns true, because 10 is higher than 9

In the examples below, we use the equal to (==) operator to evaluate an expression:

Example

int x = 10;
System.out.println(x == 10); // returns true, because the value of x is equal to 10

Example

System.out.println(10 == 15); // returns false, because 10 is not equal to 15

The Boolean value of an expression is the basis for all Java comparisons and conditions.

You will learn more about conditions in the next chapter.

what is Java Math,how to use Java Math,use of Java Math in programming,random number Java Math,coding of Java Math,best of java,Java Math,easy way to learn Java Math,step by learning Java Mathand java step

Java Math

The Java Math class has many methods that allows you to perform mathematical tasks on numbers.

Math.max(x,y)

The Math.max(x,y) method can be used to find the highest value of x and y:

Example

Math.max(5, 10);

Math.min(x,y)

The Math.min(x,y) method can be used to find the lowest value of of x and y:

Example

Math.min(5, 10);

Math.sqrt(x)

The Math.sqrt(x) method returns the square root of x:

Example

Math.sqrt(64);

Math.abs(x)

The Math.abs(x) method returns the absolute (positive) value of x:

Example

Math.abs(-4.7);

Random Numbers

Math.random() returns a random number between 0.0 (inclusive), and 1.0 (exclusive):

Example

Math.random();

To get more control over the random number, e.g. you only want a random number between 0 and 100, you can use the following formula:

Example

int randomNum = (int)(Math.random() * 101);  // 0 to 100

what is Java Strings, how to use String Length,finding character in string,java method,java classes,String Concatenation,Adding Numbers and Strings

Java Strings

Strings are used for storing text.

A String variable contains a collection of characters surrounded by double quotes:

Example

Create a variable of type String and assign it a value:

String greeting = "Hello";

String Length

A String in Java is actually an object, which contain methods that can perform certain operations on strings. For example, the length of a string can be found with the length() method:

Example

String txt = "ABCDEFGHIJKLMNOPQRSTUVWXYZ";
System.out.println("The length of the txt string is: " + txt.length());

More String Methods

There are many string methods available, for example toUpperCase() and toLowerCase():

Example

String txt = "Hello World";
System.out.println(txt.toUpperCase());   // Outputs "HELLO WORLD"
System.out.println(txt.toLowerCase());   // Outputs "hello world"

Finding a Character in a String

The indexOf() method returns the index (the position) of the first occurrence of a specified text in a string (including whitespace):

Example

String txt = "Please locate where 'locate' occurs!";
System.out.println(txt.indexOf("locate")); // Outputs 7

Java counts positions from zero.
0 is the first position in a string, 1 is the second, 2 is the third ...

String Concatenation

The + operator can be used between strings to combine them. This is called concatenation:

Example

String firstName = "John";
String lastName = "Doe";
System.out.println(firstName + " " + lastName);

Note that we have added an empty text (" ") to create a space between firstName and lastName on print.

You can also use the concat() method to concatenate two strings:

Example

String firstName = "John ";
String lastName = "Doe";
System.out.println(firstName.concat(lastName));

Special Characters

Because strings must be written within quotes, Java will misunderstand this string, and generate an error:

String txt = "We are the so-called "Vikings" from the north.";

The solution to avoid this problem, is to use the backslash escape character.

The backslash (\) escape character turns special characters into string characters:

Escape character	Result	Description
\'	'	Single quote
\"	"	Double quote
\\	\	Backslash

The sequence \" inserts a double quote in a string:

Example

String txt = "We are the so-called \"Vikings\" from the north.";

The sequence \' inserts a single quote in a string:

Example

String txt = "It\'s alright.";

The sequence \\ inserts a single backslash in a string:

Example

String txt = "The character \\ is called backslash.";

Adding Numbers and Strings

WARNING!

Java uses the + operator for both addition and concatenation.

Numbers are added. Strings are concatenated.

If you add two numbers, the result will be a number:

Example

int x = 10;
int y = 20;
int z = x + y;      // z will be 30 (an integer/number)

If you add two strings, the result will be a string concatenation:

Example

String x = "10";
String y = "20";
String z = x + y;   // z will be 1020 (a String)

If you add a number and a string, the result will be a string concatenation:

Example

String x = "10";
int y = 20;
String z = x + y;   // z will be 1020 (a String)
