java简易计算器程序代码

代码如下：

import java.util.Scanner;

public class CalculatorTest {
    public static void main(String[] args) {
        while (true) {
            Scanner scanner = new Scanner(System.in);
            System.out.println("请输入第一个数字:");
            int numberOne = scanner.nextInt();
            System.out.println("请输入第二个数字:");
            int numberTwo = scanner.nextInt();
            System.out.println("请输入符号   + - * /");
            String symbol = scanner.next();
            switch (symbol) {
                case "+":
                    System.out.println("计算结果:" + (numberOne + numberTwo));
                    break;
                case "-":
                    System.out.println("计算结果:" + (numberOne - numberTwo));
                    break;
                case "*":
                    System.out.println("计算结果:" + (numberOne * numberTwo));
                    break;
                case "/":
                    System.out.println("计算结果:" + (numberOne / numberTwo));
                    break;
                default:
                    System.out.println("符号错误请重新输入...");
            }
            System.out.println("本次程序计算完成,开始下一次计算------");
        }
    }
}
