我正在嘗試爲我正在處理的遊戲創建菜單，但是當我嘗試使用GetBufferStrategy時，Eclipse會告訴我創建一個方法。我不想要一種方法。我希望它得到緩衝策略。我對java很陌生，請解釋爲什麼我的代碼是錯誤的，所以我不再重複一遍。它想要我創建一個方法是什麼？
package homeScreen;
import java.awt.Graphics;
import java.awt.Toolkit;

public class homeScreen {
static Toolkit tk = Toolkit.getDefaultToolkit();
public static final int WIDTH = (int) tk.getScreenSize().getWidth();
public static final int HEIGHT = (int) tk.getScreenSize().getHeight();
BufferedImageLoader imageLoader = new BufferedImageLoader();
private static homeScreen home = new homeScreen();
private BufferedImage backgroundImage = null;
private BufferedImage Buttons = null;
public static void main(String args[]){
JFrame frame = new JFrame("Game");
frame.pack();
frame.setSize(WIDTH, HEIGHT);
frame.setResizable(false);
frame.setLocationRelativeTo(null);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setVisible(true);
home.loadImages();
}
private void loadImages() {
try {
backgroundImage = imageLoader.loadImage("/res/HomeScreen.png");
Buttons = imageLoader.loadImage("/res/MainScreenButtons.png");
} catch (IOException e) {
e.printStackTrace();
}
home.display();
}
private void display(){
BufferStrategy buffStrat = this.getBufferStrategy();
Graphics g = buffStrat.getDrawGraphics();
if(buffStrat == null){
createBufferStrategy(3);
return;
}

g.dispose();
buffStrat.show();
