How to Find the Sum of Two Numbers in Java

Last Updated: September 20, 2021

Finding the sum of two numbers is simple, but it can get tedious if the numbers are big. Here is how you can create a Java program to find the sum of two numbers.

Steps

1
Plan your program. Finding the sum of two numbers isn't difficult, but it is always a good practice to plan your program before beginning to code. Understand that you'd need two inputs/ parameters from the user for this program: the two numbers.
2
Write the code. Finding the sum of two numbers means the simple addition of both the numbers.^{[1]

- Create a separate variable to store the value of the sum. This can be of the type int.
- The formula to find the sum is:
  
  Sum = First Number + Second Number
- To get these parameters (inputs) from the user, try using the Scanner function in Java.

3
Display the output. Once the program has calculated the sum, display it to the user. Use the System.out.print or System.out.println (to print on a new line) function, in Java, for this.^{[2]

Yes. You may want to have the user specify what kind of shape before taking in any other input (such as dimensions).

How can I find the sum of 46 and 56?

Community Answer

Assume there are three integers (a, b, c): int a = 46; int b = 56; int c = a + b; System.out.println(c); Don't forget the semicolons.

Sample Code

mScanner.nextInt();
      
      sum = firstNumber + secondNumber;
      
      System.out.println("The sum of the two numbers you entered = " + sum);
    }
