Chapter 5- The do-while loop in Java

• do-while loop:

This loop is similar to a while loop except for the fact that it is guaranteed to execute at least once

/* do {

            //code

} while (condition);            //Note this semicolon */

• while – checks the condition & executes the code
• do-while – executes the code & then checks the condition

Quick Quiz: Write a program to print first n natural numbers using a do-while loop.

package com.company;

public class cwh_22_ch4_do_while {
    public static void main(String[] args) {
//        int a = 0;
//        while(a<5){
//            System.out.println(a);
//            a++;
//        }
        int b = 10;
        do {
            System.out.println(b);
            b++;
        }while(b<5);

        int c = 1;
        do{
            System.out.println(c);
            c++;
        }while(c<=45);

    }
