Find the Sum of Two Numbers in Java

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.
    • 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.

Sample Code

Tips

  • Try expanding your program to perform multiple mathematical calculations.
  • Try making a GUI, which will make the program much more interactive and easier to use.
