Java – Calculate Sum of Two Numbers

Write A Java Program to calculate the sum of two numbers. In the first program, we have predefined values for two integer variables and calculate the sum of them.

public class AddNumbers {

   public static void main(String[] args) {
        
      int num1 = 20;
      int num2 = 25;
      int sum;
	  
      //Calculate sum
      sum = num1 + num2;

      System.out.println("Sum is: " + sum);
   }
}

public class AddNumbers {

public static void main(String[] args) {

int num1 = 20;

int num2 = 25;

int sum;

//Calculate sum

sum = num1 + num2;

System.out.println("Sum is: " + sum);

}

Compile and run this program:

javac AddNumbers.java
java AddNumbers

Output:

Sum is: 45
