While Loop In Java


A while loop declaration in Java programming language frequently performs a target report as long as a given form is true.


The syntax of a while loop is

while(Boolean_expression) {
   // Statements

Here, statement(s) might be a solitary account or a block of statements. The state might be any look, and true is any non-zero value.

When executing, if the boolean_expression result is true, then the actions inside the loop will be executed. This will continue as long as the expression result is true.

When the state becomes false, the program manager bypasses the row instantly following the loop.

Java While Loop

Here, the key tip of the as the loop is that the loop might not ever run. When the look is tested and the effect is false, the loop remains will be principled and the first account after the while loop will be affected.

public class Test {

   public static void main(String args[]) {
      int x = 10;

      while( x < 20 ) {
         System.out.print("value of x : " + x );

This will produce the following result:


value of x : 10
value of x : 11
value of x : 12
value of x : 13
value of x : 14
value of x : 15
value of x : 16
value of x : 17
value of x : 18
value of x : 19
