Java Program to Subtract One Number From Another Number

Java Program to Subtract Two Numbers

Last Updated: 14 August, 2022

On this tutorial page we are going to learn how to write a Java program to subtract two numbers (integer or float) and produce the result.

There are two programs given below. In the first program, both numbers are written in the program itself. In the second program, user is asked to enter the two numbers and the program calculates the subtraction of the input numbers and produce the subtraction of both numbers as an output.

subtraction of two numbers = number1 - number2

Let's see the Java program implementation.

Program 1: A Java Program to Subtract Two Numbers

  public class Subtract {
    public static void main(String[] args) {
      float num1 = 150.55f;
      float num2 = 50.25f;
      // Subtracting two numbers
      float result = num1 - num2;
  
      System.out.println("First Number: " + num1);
      System.out.println("Second Number: " + num2);
      System.out.println("Subtract of two numbers: " + result);
    }
  }

Program 2: A Java Program to Subtract Two Numbers Using the Scanner Class (User Input)

  import java.util.Scanner;
  public class Subtract2 {
    public static void main(String[] args) {
      Scanner scanner = new Scanner(System.in);
      System.out.print("Enter first number: ");
      float num1 = scanner.nextFloat();
      System.out.print("Enter second number: ");
      float num2 = scanner.nextFloat();
      // Subtracting two numbers
      float result = num1 - num2;
      System.out.println("Subtract of two numbers: " + result);
      scanner.close();
    }
  }

Enter first number: 100.5
Enter second number: 50.5
Subtract of two numbers: 50.0
