Java example for while loop demonstration

This program will demonstrate example of while loop in java, the use of while is similar to c programming language, here we will understand how while loop works in java programming with examples.

while Loop Example in Java

Programs 1) Print your name 10 times.

//Java program to print name 10 times using while loop
 
public class PrintNames
{
    public static void main(String args[]){
         
        int loop; //loop counter declaration
        final String name="Mike"; //name as constant
         
        loop=1; //initialization of loop counter
        while(loop<=10){
            System.out.println(name);
            loop++; //increment
        }
         
    }
}

Output

    Mike
    Mike
    Mike
    Mike
    Mike
    Mike
    Mike
    Mike
    Mike
    Mike

Programs 2) Print numbers from 1 to N.

//Java program to print numbers from 1 to N
 
import java.util.Scanner;
 
public class PrintNumbers
{
    public static void main(String args[]){
        int loop; //declaration of loop counter
        int N; 
         
        Scanner SC=new Scanner(System.in);
         
        System.out.print("Enter value of N: ");
        N=SC.nextInt();
         
        loop=1;
        while(loop<=N){
            System.out.print(loop +" ");
            loop++;
        }
         
    }
}

Output

Enter value of N: 50
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 
16 17 18 19 20 21 22 23 24 25 26 27 
28 29 30 31 32 33 34 35 36 37 38 39 
40 41 42 43 44 45 46 47 48 49 50
