    public void Reset()

    }

    public boolean isClicked(Object source)
    {
        if(source == button)
            return true;
        else 
            return false;
    }




}

编辑我在整个代码正文中进行了编辑。据Eclipse所知,myColor右括号“应该”在classBody之后。

Eclipse希望我删除myColor的右括号,并用分号替换它;无论我是否放置分号,Eclipse告诉我闭合括号不应该在那里,如果我将其删除,请将我的classBody闭合括号读作EnumBody闭合括号。

我不知道到底发生了什么,但这肯定会导致在课堂上发生奇怪的事情(为棋盘游戏制作一个Tile类+对象)。

通过奇怪的事情,我的意思是如果我希望Eclipse将Tile读成没有错误,我不能从另一个类创建一个Tile对象数组。

答案 0 :(得分:0)

不完全确定您收到的错误消息。以下示例EnumIssue.java正常工作:

public class EnumIssue {

    enum Job
    {
        SPAWN, KING, NORM
    }
    enum myColor
    {
        RED, BLACK
    }

    public static void main(String[] args) {
        Job j = Job.SPAWN;
        myColor c = myColor.BLACK;
        System.out.println(j);
        System.out.println(c);
    }
}

<强>输出:

SPAWN
BLACK

在提供完整代码后添加:

在类Tile中移动变量声明。更新后的代码段如下:

:
:
import javax.swing.JPanel;

enum Job{SPAWN, KING, NORM};
enum myColor{RED, BLACK};

//This is where current variable declarations are. Move them inside class.

public class Tile
{
    //This is where variable declarations are moved to. 
    int tileRow;
    int tileCol;
    Job job;
    myColor side;
    JButton button;
    Checker piece;
    Color color;

    public Tile(int posRow, int posCol, JPanel panel, ActionListener listener)
    {
        int tileRow = posRow;
        :
        :
