Java While Loop

Learn Java while loop, do while loop, infinite loops, examples, and loop control techniques.

What is While Loop?

while loop repeats code while condition is true.

Syntax

while(condition){

    code;

}

Example

int i = 1;

while(i <= 5){

    System.out.println(i);

    i++;

}

do while Loop

int i = 1;

do{

    System.out.println(i);

    i++;

}while(i <= 5);

Difference

while checks condition first
do while runs at least once
