In this chapter we will see while loop in Java it is used to to iterate path of the program on certain condition. in an another word run a block of code with a specified condition is called loop. with while loops are also the same condition applies.




While loop

if condition is true then while will execute the block of code.


syntax:

while (condition) {
  // code block to be executed
}


Example:

public class JavaApplication {

    public static void main(String[] args) {

        int i = 0;
        while (i < 4) {
            System.out.println(i);
            i++;
        }

    }

}



output:

run:
0
1
2
3

Thanks, May this example will help you.
