Question

Java program should ask the user for the maximum number to print out to and then print each evennumber starting from 0 to the maximum. You may want to use % operator which gives you the remainder. Some results of the operator is as follows:

• 0 % 2 = 0

• 1 % 2 = 1

• 2 % 2 = 0

• 3 % 2 = 1

• 4 % 2 = 0

Answer 1

import java.util.Scanner;

public class EvenNumbers {

      public static void main(String[] args) {

            // TODO Auto-generated method stub

            //Scanner function to get the input from keyboard

            Scanner scan = new Scanner(System.in);

            //Ask the user to enter Maximum number

            System.out.print("Maximum number to print: ");

            int max= scan.nextInt();

            //printing the maximum number

            System.out.println("Maximum number: "+max);

            System.out.println("Even number upto "+max);

            //Looping from 0 to maximum number to print the numbers upto maximum

            for (int i=0; i<=max; i++){

                  if(i%2 ==0){

                        //If the remainder is 0 then the number is even

                        //If the number is even it is printed otherwise it is not printed

                        System.out.print(i+" ");

                        //If you want to print number per line you can use System.out.println in the above statement

                  }

            }

      }

}

Output:
