Solution - Arithmetic calculation

Problem.

Write a Java program that prompts the user to enter two integers, and then displays the sum, difference, product, and quotient of the two numbers. Use a method to perform the calculation and display the results.

Solution.

ArithmeticOperations.java

import java.util.Scanner;

public class ArithmeticOperations {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        System.out.print("Enter first integer: ");
        int num1 = scanner.nextInt();
        System.out.print("Enter second integer: ");
        int num2 = scanner.nextInt();
        performArithmetic(num1, num2);  // 将计算和显示的任务分配给performArithmetic()方法，这里只调用
    }

    public static void performArithmetic(int num1, int num2) {
        int sum = num1 + num2;
        int difference = num1 - num2;
        int product = num1 * num2;
        double quotient = num1 / (double)num2;
        System.out.println("Sum: " + sum);
        System.out.println("Difference: " + difference);
        System.out.println("Product: " + product);
        System.out.println("Quotient: " + quotient);
    }
}
