Java 类/方法的问题

所以我有一段代码，我正在为我的AP计算机科学课程学习，当我编译的时候，我得到了大量的错误，即使当我看它的时候，它看起来很好，一切都井然有序。所有的错误都来自我的myClock类和RepairShop类

public class APCS_104_Time {

public static void main(String[] args) {
        tester tester = new tester();
    }
}

    class myClock {

    private int minute;
    private int hour;

    public myClock() {
        hour = 2;
        minute = 3;
    }

    public myClock(int minute, int hour) {

        public int getHour() {
            hour = IO.getInt("Enter the hour");
            return hour;
        }

        public int getMinute() {
            minute = IO.getInt("Enter the minute");
            return minute;
        }

        public void int setMinute(int minute) {
            this.minute = minute;
        }

        public void int setHour(int hour) {
            this.hour = hour;
        }

        public String toString() {
            if (minute < 10) {
                return (hour + ":0" + minute);
            }
            else {
                return (hour + ":" + minute); 
            }
        }
    }
}

class RepairShop {

    public void int springForward(myClock time) {
        hour++;
    }

    public void int resetClock(myClock time) {
        hour = 2;
        minute = 3;
    }

    public int cloneClock(myClock time) {

        myClock copy = myClock myClock.clone();
        return myClock;
    }
}

class Tester { 

    Tester() {

        myClock time = new myClock();

        System.out.printf("The time is: " + myClock(2, 20));
    }
}

您需要解决很多问题：

首先

//This myClock constructor can't contain other method!    
public myClock(int minute, int hour) {

            public int getHour() {
                hour = IO.getInt("Enter the hour");
                return hour;
            }

    ...
    }

第二件事是，setter是void，不能是void和int，从这类方法中删除int：

public void int setMinute(int minute) {
            this.minute = minute;
}

第三件事是，小时是myClock中的一个属性，不能在其他类中使用：

private int hour;

第四点是你需要遵循惯例。类名必须是大写的第一个字母。例如myClock->myClock

在解决了以上所有问题后，我相信您可以理解并修复代码。如果没有，就告诉我

希望这有帮助

如果可以，我建议使用IDE、代码辅助和语法高亮显示，这将非常有帮助。
