Display even numbers between 1 to 100 in java [in 2 ways]-CY

Display all even  numbers between 1 to 100 in java

In this article you can learn to write a java program that will display all the even numbers between 1 and 100 with 2 different approaches.

Approach:-1 "print all even numbers between 1 and 100 in java using for loop"

 public class usingForLoop {

    public static void main(String[] args){

      System.out.println("Using For Loop");

      for(int i = 1; i <= 100; i++)

      {

        if(i % 2 == 0)

        {

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

        }

      }

    }

}

Explanation

In this program I have used for loop. Here I have fetched all the numbers from 1 to 100.

And in if statement, I have checked which numbers are even using modulus operator (%). 

Now those numbers satisfy the even numbers condition i.e i % 2 == 0, has been printed.

Output

Approach:-2 "display even numbers between 1 and 100 in java using while loop"

 public class usingWhileLoop {

    public static void main(String[] args){

      System.out.println("Using while loop");

      int num = 2;

      

      while(num <= 100)

      {

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

        num = num + 2;

      }

    }

} 

+

Explanation

In this approach I haven't use if condition, here I have simply added 2 to each numbers. 

See if you add 2 to an even number, then the result number will be an even number. 

• Ex:- 4 is even, now 4 + 2 = 6, here 6 also even number. 

Here I have started the loop from 2 and at each iteration I am adding 2 to the new number.
