While loop

What is a While Loop?
*A while loop is a control flow statement in programming that repeatedly executes a block of code as long as a specified condition is true
*while loop statement repeatedly executes a code block as long as a given condition is true.

Syntax of while Loop
The syntax of a while loop is −

while(Boolean_expression) {
// Statements
}
while (condition) {
// code to be repeated
}

Example:
int i = 1;
while (i <= 5) {
System.out.println(i);
i++;
}

Output:

1
2
3
4
5

**Why Use a While Loop?

Reason Explanation

* To repeat code until a condition becomes false
      *when you don’t know how many times the loop should run.

     While Loop

The while loop loops through a block of code as long as a specified condition is true:

SyntaxGet your own Java Server
while (condition) {
// code block to be executed
}
In the example below, the code in the loop will run, over and over again, as long as a variable (i) is less than 5:

Example
int i = 0;
while (i < 5) {
System.out.println(i);
i++;
}
