Java 9 Splashscreen Splashscreen.getSplashScreen() 问题；

Question

我在让我的 java 闪屏工作时遇到一些小问题!我正在使用 Eclipse 和 Java 9。引用 https://docs.oracle.com/javase/tutorial/uiswing/misc/splashscreen.html我尝试使用方法 SplashScreen.getScreenSplash();。但这是行不通的。相反，错误消息表明该方法不存在。这是我的代码:

import java.awt.*;
import javax.swing.*;

public class SplashScreen extends JFrame {
    private SplashScreen sp;
    private JLabel label;

    public SplashScreen() {
        super("SplashScreen");
        setSize(300, 200);
        setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
        setLayout(new BorderLayout());
        label = new JLabel("Welcome");
        label.setFont(new Font("Arial", Font.BOLD, 20));
        add(label, BorderLayout.CENTER);
        sp = SplashScreen.getScreenSplash();

        if(sp != null) {
            Graphics2D g = sp.createGraphics();
            g.setComposite(AlphaComposite.Clear);
            g.setPaintMode();
            //printing the progress bar
            try {
                for(int i = 0; i <= 100; i++) {
                g.setColor(Color.BLACK);
                g.fillRect(100, 200, 200, 20);
                g.setColor(Color.GREEN);
                g.fillRect(100, 200, 2*i, 20);
                sp.update(g);
                Thread.sleep(100);
                }
                catch (Exception e) {
                    System.out.println(e.getMessage());
                }
            }
        }
        setVisible(true);


    }

}    

有谁知道发生了什么变化吗？谢谢!

 SplashScreen.getScreenSplash() !=  SplashScreen.getSplashScreen();

你把词搞混了。
