What are even numbers?

Even numbers are any integer number that can be exactly divided by 2 or we can say that they are multiples of 2.

Example: 0, 2, 4, 6, 10, etc.

So for checking a number is even follow the steps below,

  • Divide the number by 2
  • Check the remainder
  • if it is zero, the number is EVEN

How to use a java program to display even numbers?

The logic behind this program is to find the remainder of the number using the mod (%) operator in Java and check whether it is zero or not. So first, we have to declare the class EvenNum.Then by using a for loop, from i = 1 to 500, check if i mod 2 equals 0, if true it is an even number so display i, otherwise check next number i.

We can also use this logic to display the numbers from 1 to 200 that are even, by just changing the boundary value 500 to 200 in the for loop.

ALGORITHM

STEP 1: Declare the class EvenNum with a public modifier.

STEP 2: Open the main() to start the program, Java program execution starts with the main()

STEP 3: By using a for loop set i=1,check i<=500 do step 4.

STEP 4: Check if i%2 == 0 ,if true then display i 


To display the even numbers using the java program, we need to understand the below concepts, We recommend to refer those for a better understanding

Java Source Code

                                          public class EvenNum {
    public static void main(String args[]) {
        System.out.println("Even Numbers From 1 to 500");
        for (int i = 1; i <= 500; i++) {
            if (i % 2 == 0) {
                System.out.print(i + " ");
            }
        }
    }
}
                                      

OUTPUT
