# Program to find the sum of numbers in a given range in Java

## Sum of numbers in a given range :

In this article we will perform addition on natural numbers in a given range. So for this, we have to ask the user to enter two numbers which will denote the starting and ending of the range for adding all natural numbers between that range.

For better understanding let’s suppose two values 3 and 8,

Then, Sum of all natural numbers between 3 and 8 will be (3+4+5+6+7+8) = 33.

So we create a java program to calculate the sum of all natural numbers in a given range. ### Working :

Step 1 : Ask the user to enter two numbers which will denote the starting and ending of the range for adding all natural numbers between that range.

Step 2 : Declare a variable to store the addition and initialize it with 0.

Step 3 : Use a loop to perform iterations for adding all natural numbers from starting range to the ending range.

Step 4 : Use a statement for addition purpose.

Step 5 : Print the result.

### Code in Java :

`//Java program to print the sum of numbers in a given rangeimport java.util.Scanner;public class sum_of_numbers_in_range{		public static void main(String[] args)	{		//scanner class declaration		Scanner sc = new Scanner(System.in);		//input from user		System.out.print("Enter starting number : ");						int start = sc.nextInt();		System.out.print("Enter ending number : ");						int end = sc.nextInt();		//declare a variable to store sum		int sum = 0;		//loop to add n natural numbers		for(int i = start ; i <= end ; i++)		sum=sum+i;		//display the sum		System.out.print("Sum of numbers in the range from "+start+" to "+end+" is "+sum);		//closing scanner class(not compulsory, but good practice)		sc.close();														}}`

### Output :

`Enter starting number : 1Enter ending number : 5Sum of numbers in the range from 1 to 5 is 15Enter starting number : 2Enter ending number : 14Sum of numbers in range 2 to 14 is 104`
