java为什么从对象获取信息时会出现堆栈溢出错误？
您好，我正在尝试用java创建一个宫殿游戏。我参加了solo learn课程，但从未真正学会如何处理堆栈溢出错误。我的问题都没有在网上找到。目前处于可变状态
AllCards aceClover = new AllCards();
上面说有个StackOverflowerr错误，我不知道为什么

在这个类中，我要做的是创建一个带有特定变量的对象。然后所有这些变量都被赋值，但一旦赋值，我需要一个函数，该函数获取一个随机整数，以选择某个对象，将信息发送给另一个类，然后该类将其显示在屏幕上
package MainClasses;
import java.awt.*;
import java.io.*;
import java.util.Random;
import javax.imageio.ImageIO;
public class DrawBoard extends Component{
AllCards accessor = new AllCards();
public void paint(Graphics g) { // function to draw onto the window
Graphics2D g1 = (Graphics2D)g; // the component being used to access and write to the window
g1.clearRect(0, 0, getWidth(), getHeight()); // clears rectangle every frame
g1.setBackground(Color.green); // sets background color
accessor.randomizer();
g1.drawImage(accessor.imageExtract, 100, 100, null);
}
}
这是我用来从对象中提取信息的函数。我不是100%确定它能工作，但从以前的版本来看，它显示得很好
package MainClasses;
import java.awt.Color;
import javax.swing.*;
public class Main extends JFrame{
public static void main(String[] args) {
JFrame f = new JFrame("Palace");
f.setSize(1920,1080);
f.setResizable(false);
f.setVisible(true);
f.setDefaultCloseOperation(EXIT_ON_CLOSE);
f.add(new DrawBoard());
}
}
这是我用来创建JFrame的类，以备需要
