狂神说Java作业：写一个计算器，要求实现加减乘除功能，并且能够循环接收新的数据，通过用户交互实现

思路推荐：

1. 写4个方法：加减乘除
2. 利用循环+switch进行用户交互
3. 传递需要操作的两个数
4. 输出结果

import java.util.Scanner;

public class homework {
    public static void main(String[] args) {

        Scanner scanner = new Scanner(System.in);
        System.out.println("请选择您要进行的操作：1.加 2.减 3.乘 4.除 5.退出");
        int choice = scanner.nextInt();
        while (choice != 5)
        {
            homework homework = new homework();
            double i = homework.calculate(choice);
            System.out.println(i);
            System.out.println("请选择您要进行的操作：1.加 2.减 3.乘 4.除 5.退出");
            choice = scanner.nextInt();
        }
        if(choice==5)
        {
            System.out.println("感谢使用本计算器");
        }

        scanner.close();

    }
    public double calculate(int choice)
    {
        int sum = 0;
        switch (choice)
        {
            case 1:
            {
                System.out.println("请输入加数1：");
                Scanner scanner1 = new Scanner(System.in);
                int plus1 = scanner1.nextInt();
                System.out.println("请输入加数2");
                int plus2 = scanner1.nextInt();
                sum = plus1 + plus2;
                break;
            }

            case 2:
            {
                System.out.println("请输入被减数：");
                Scanner scanner1 = new Scanner(System.in);
                int plus1 = scanner1.nextInt();
                System.out.println("请输入减数");
                int plus2 = scanner1.nextInt();
                sum = plus1 - plus2;
                break;
            }

            case 3:
            {
                System.out.println("请输入乘数1：");
                Scanner scanner1 = new Scanner(System.in);
                int plus1 = scanner1.nextInt();
                System.out.println("请输入乘数2");
                int plus2 = scanner1.nextInt();
                sum = plus1 * plus2;
                break;
            }

            case 4:
            {
                System.out.println("请输入被除数：");
                Scanner scanner1 = new Scanner(System.in);
                int plus1 = scanner1.nextInt();
                System.out.println("请输入除数");
                int plus2 = scanner1.nextInt();
                sum = plus1 / plus2;
                break;
            }

        }
        return sum;

    }
