匹配Oval与Graphics字符串的颜色和碰撞测试

Question

我正在为我的工程项目制作游戏，并且我遇到了一些问题。我认为我的代码中有一部分可以正常工作但不起作用。你能告诉我我做错了什么吗？这是我的两个类中的代码，名为AlphabetsColoured和testAlphabets。有一小部分代码可以用字母与椭圆进行碰撞检测，但不能正常工作。请帮帮我。

import java.awt.*;     
import java.util.*;

public class AlphabetsColoured 
{

    private Color quescolour, anscolour;
    private int x, y, width, height; 


    public void getQuestion(Graphics g,String alphabet,int x, int y, Color colour)
    {
        Graphics2D g2 = (Graphics2D) g;

        Font font = new Font("Chalkduster", Font.BOLD+Font.PLAIN, 70);
        g2.setFont(font);
        g2.setColor(this.quescolour = colour);
        g2.drawString(alphabet, x, y);
    }

    public void getAnswers(Graphics g, String alphabet,int x, int y, Color colour)
    {
        Graphics2D g2 = (Graphics2D) g;

        Font font1 = new Font("Bloody", Font.BOLD+Font.PLAIN, 30);
        g2.setFont(font1);
        g2.setColor(this.anscolour = colour);
        g2.drawString(alphabet, x, y);
