Question

Write a java program to perform the four arithmetic operation using function.

Answer 1

Here's an example of a Java program that performs the four arithmetic operations using functions:

```java
import java.util.Scanner;

public class ArithmeticOperations {

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

System.out.print("Enter the first number: ");
double num1 = scanner.nextDouble();

System.out.print("Enter the second number: ");
double num2 = scanner.nextDouble();

System.out.println("Addition: " + add(num1, num2));
System.out.println("Subtraction: " + subtract(num1, num2));
System.out.println("Multiplication: " + multiply(num1, num2));
System.out.println("Division: " + divide(num1, num2));

scanner.close();
}

public static double add(double num1, double num2) {
return num1 + num2;
}

public static double subtract(double num1, double num2) {
return num1 - num2;
}

public static double multiply(double num1, double num2) {
return num1 * num2;
}

public static double divide(double num1, double num2) {
return num1 / num2;
}
}
```

In this program, we have four functions `add`, `subtract`, `multiply`, and `divide` that perform the respective arithmetic operations using the given input numbers. The `main` function takes two numbers as input from the user, calls these functions with the input numbers, and displays the results of the operations.
