Sum of First 10 Natural Numbers in Java Using For Loop. In this program you will learn how to write a program to sum of the natural numbers in java for beginners. In Java programming language, the sum of natural numbers. In the Java programming language, this is an example of a simple set program. The sum of natural numbers program is essentially an addition program that is run in a for loop

## For Loop and How it Works

A for-loop is a control flow statement in computer science that specifies iteration and allows code to be performed repeatedly. When the number of iterations is known before entering the loop, for-loops are commonly employed. The startup of the loop, when we set our counter to a beginning value. Before the loop starts, the initialization statement is executed. The test statement determines whether or not a particular condition is true.

## Natural Number in Java

Natural numbers are a subset of the number system that encompasses all positive integers from 1 to infinity and are used for counting. It does not include the number zero (0). 1,2,3,4,5,6,7,8,9,… are also known as counting numbers. Natural numbers are a subset of real numbers, which only contain positive integers such as 1, 2, 3, 4,5, and 6, as well as zero, fractions, decimals, and negative numbers.

## Sum of First 10 Natural Numbers in Java Using For Loop

```
public class Main
{
public static void main(String[] args)
{
int number = 10, sum = 0;
for(int i = 1; i <= number; ++i)
{
sum =sum + i;
}
System.out.println("Sum = " + sum);
}
}
```

Output:

Sum = 55
