Sum of Even and Odd number in Java

Sum of Even Number:

In this tutorial, we will discuss how to calculate the sum of even numbers using a java programming language. It is too simple just some line program.

The sum of even numbers in mathematics

Example:

Even numbers 2,4,6,7,8,10.....

The sum of even number 2+4+6+8 = 20.

Now, Sum of even number using java:

Program:

 import java.util.*;
 public class MyClass {
    public static void main(String args[]) {
    System.out.println("Enter the Range: ");
    Scanner f=new Scanner(System.in);
    int x=f.nextInt();
    int i,sum=0;
    for(i=0;i<=x;i=i+2){
        sum=sum+i;
    }
      System.out.println("Sum of Even number = " + sum);
    }
 }

Output:

Enter the Range:

Sum of Even number = 20

Sum of Odd Number:

After, the sum of the Even numbers, We discuss how to find the sum of the odd numbers using java language.

Also, the sum of odd numbers in mathematics

Example:

Odd numbers 2,4,6,7,8,10.....

The sum of Odd number 1+3+5+7 = 20.

Now, Sum of Odd numbers using java:

Program:

 import java.util.*;
 public class MyClass {
    public static void main(String args[]) {
    System.out.println("Enter the Range: ");
    Scanner f=new Scanner(System.in);
    int x=f.nextInt();
    int i,sum=0;
    for(i=1;i<=x;i=i+2){
        sum=sum+i;
    }
      System.out.println("Sum of Even number = " + sum);
    }
 }

Output:

Enter the Range:

Sum of Even number = 16
