java算术测试加减乘除

好的，我可以为您提供一个简单的Java算术测试程序，可以测试加减乘除四则运算。以下是代码示例：

import java.util.Scanner;

public class ArithmeticTest {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        int num1, num2, result;
        char operator;

        System.out.println("请输入第一个数字：");
        num1 = scanner.nextInt();

        System.out.println("请输入第二个数字：");
        num2 = scanner.nextInt();

        System.out.println("请输入运算符（+、-、*、/）：");
        operator = scanner.next().charAt(0);

        switch (operator) {
            case '+':
                result = num1 + num2;
                System.out.println(num1 + " + " + num2 + " = " + result);
                break;
            case '-':
                result = num1 - num2;
                System.out.println(num1 + " - " + num2 + " = " + result);
                break;
            case '*':
                result = num1 * num2;
                System.out.println(num1 + " * " + num2 + " = " + result);
                break;
            case '/':
                if (num2 == 0) {
                    System.out.println("除数不能为0！");
                    break;
                }
                result = num1 / num2;
                System.out.println(num1 + " / " + num2 + " = " + result);
                break;
            default:
                System.out.println("您输入的运算符不正确！");
                break;
        }
    }
}

您可以尝试在命令行或者集成开发环境中运行此程序，输入相应的数字和运算符，程序会计算并输出结果。
