使用java语言写出一个可以进行连加连除的计算器代码

好的，以下是可以进行连加连除的计算器代码：

import java.util.Scanner;

public class Calculator {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        double result = 0;

        System.out.print("请输入第一个数字：");
        double num1 = scanner.nextDouble();
        result = num1;

        while (true) {
            System.out.print("请输入操作符：(+, -, *, /, q退出) ");
            String operator = scanner.next();

            if ("+".equals(operator)) {
                System.out.print("请输入要加的数字：");
                double num = scanner.nextDouble();
                result += num;
                System.out.println("结果是：" + result);
            } else if ("-".equals(operator)) {
                System.out.print("请输入要减的数字：");
                double num = scanner.nextDouble();
                result -= num;
                System.out.println("结果是：" + result);
            } else if ("*".equals(operator)) {
                System.out.print("请输入要乘的数字：");
                double num = scanner.nextDouble();
                result *= num;
                System.out.println("结果是：" + result);
            } else if ("/".equals(operator)) {
                System.out.print("请输入要除的数字：");
                double num = scanner.nextDouble();
                if (num == 0) {
                    System.out.println("除数不能为0");
                    continue;
                } else {
                    result /= num;
                    System.out.println("结果是：" + result);
                }
            } else if ("q".equals(operator)) {
                break;
            } else {
                System.out.println("操作符不正确，请重新输入。");
            }
        }
        System.out.println("感谢使用！");
    }
}
