Looping in Java

Loops allow us to repeat the same set of instructions a number of times until a certain pre-specified condition is met. There are different looping statements in Java.

for loop

public static void main(String[] args){
 for (int i = 1; i <=  3; i++){
 System.out.println("I: " + i);
 }
 }

Output

I: 1
 I: 2
 I: 3

while loop

public class Main {
 public static void main(String[] args){
 int i = 1;
 while(i<= 3){
 System.out.println("I: " + i);
 i++;
 }
 }
 }

Output

I: 1
 I: 2
 I: 3

do…while loop

public class Main {
 public static void main(String[] args){
 int i = 1;
 do{
 System.out.println("I: " + i);
 i++;
 }while(i<=3);
 }
 }

Output

I: 1
 I: 2
 I: 3
