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。JavaSE，Java

import org.omg.PortableInterceptor.SYSTEM_EXCEPTION;

import java.util.Scanner;

public class Text1 {
    public static void main(String[] args) {
        Text1 text1 = new Text1();


        Scanner scanner = new Scanner(System.in);
        while (scanner.hasNextDouble()) {
            double x = scanner.nextDouble();
            String str = scanner.next();
            double y = scanner.nextDouble();

            switch (str) {
                case "+":
                    text1.add(x, y);
                    break;
                case "-":
                    text1.minus(x, y);
                    break;
                case "*":
                    text1.mutiply(x, y);
                    break;
                case "/":
                    text1.except(x, y);
                    break;
            }
            System.out.println("输入任意字母退出");
        }
        scanner.close();


    }
    public void add(double x,double y){
        System.out.println(x+y);
    }
    public void minus(double x,double y){
        System.out.println(x-y);
    }
    public void mutiply(double x,double y){
        System.out.println(x*y);
    }
    public void except(double x,double y){
        if(y==0){
            System.out.println("Eorr！被除数不能是0！");
        }else {
            System.out.println(x/y);
        }
    }
