## In this program, you’ll learn how to add two numbers in java.

To properly understand this Program add two numbers, you should have the knowledge of following Java programming topics:

- Java Variables

#### Program to add two numbers

public class Add{ public static void main(String []args){ int num1=10; int num2=20; int res=num1+num2; System.out.println("The sum of "+num1+" and "+num2+" is "+res); } }

**Output:**

The sum of 10 and 20 is 30

In the above program first, we initialize the variables *num1* and *num2* with the value 10 and 20 respectively. And by using the ‘+’ operator we add the numbers and store the result in the variable res.

Above java program can also be used for performing a different mathematical operation by changing the (+) operator, we can subtract (-), multiply(*), divide(/) or find the remainder(%) of two numbers.
