Java Program to Add Two Integers

In this program, you'll learn to store and add two integer numbers in Java. After addition, the final sum is displayed on the screen.

To understand this example, you should have the knowledge of the following Java programming topics:

• Java Operators
• Java Basic Input and Output

Example: Program to Add Two Integers

class Main {

  public static void main(String[] args) {
    
    System.out.println("Enter two numbers");
    int first = 10;
    int second = 20;
    
    System.out.println(first + " " + second);

    // add two numbers
    int sum = first + second;
    System.out.println("The sum is: " + sum);
  }
}

Output:

Enter two numbers
10 20
The sum is: 30

In this program, two integers 10 and 20 are stored in integer variables first and second respectively.

Then, first and second are added using the + operator, and its result is stored in another variable sum.

Finally, sum is printed on the screen using println() function.
