Java Program to Perform Arithmetic Operations Using Methods | Switch Case

Java program to perform arithmetic operations using methods and switch case.

In this article, you will learn how to make a java program to perform arithmetic operations using methods and switch case.

 

Example

 

You should have the knowledge of the following topics in Java programming to understand this program.

• Java Arithmetic operators
• Java java.util.Scanner package
• Java main() method
• Java System.out.println() function
• Java Methods
• Java Switch Case

 

There we will perform these arithmetic operations like Sum, Difference, Multiplication, Division, and Modulus.

 

In this article, we solve this problem in three methods:

1. Using the normal calculation
2. Using the method
3. Using the switch case

Source Code

// Java Program to Perform Arithmetic Operations
import java.util.Scanner;

public class Main {
    public static void main(String[] args) {
        Scanner in = new Scanner(System.in);

        System.out.println("Enter any two positive integer numbers:");

        // Reading data using readLine
        int p = in.nextInt();
        int q = in.nextInt();
        int sum, sub, mul, mod;
        float div;

        sum = p + q;
        sub = p - q;
        mul = p * q;
        div = p / q;
        mod = p % q;

        System.out.println("\nSUM         " + p + " + " + q + " = " + sum);
        System.out.println("DIFFERENCE  " + p + " - " + q + " = " + sub);
        System.out.println("PRODUCT     " + p + " * " + q + " = " + mul);
        System.out.println("QUOTIENT    " + p + " / " + q + " = " + div);
        System.out.println("MODULUS     " + p + " % " + q + " = " + mod);
    }
}

Explanation

In this given program, we have taken inputs 5 and 8 from the user then we applied arithmetic operations on these integer numbers.

Then this will be returned the output values of this program.
