使用进度条（如Eclipse）制作启动屏幕

当计数器达到指定的数字时，它应停止在（300）位置，直到不停止计时器并隐藏启动画面时，它一直保持计数。

下面的代码似乎很好用（存在致命缺陷，计数器可能花费比文件加载更长的时间，反之亦然）：

import java.awt.Color;import java.awt.Container;import java.awt.Font;import java.awt.HeadlessException;import java.awt.event.ActionListener;import javax.swing.*;public class SplashScreen extends JWindow {    static boolean isRegistered;    private static JProgressBar progressBar = new JProgressBar();    private static SplashScreen execute;    private static int count;    private static Timer timer1;    public SplashScreen() {        Container container = getContentPane();        container.setLayout(null);        JPanel panel = new JPanel();        panel.setBorder(new javax.swing.border.EtchedBorder());        panel.setBackground(new Color(255, 255, 255));        panel.setBounds(10, 10, 348, 150);        panel.setLayout(null);        container.add(panel);        JLabel label = new JLabel("Hello World!");        label.setFont(new Font("Verdana", Font.BOLD, 14));        label.setBounds(85, 25, 280, 30);        panel.add(label);        progressBar.setMaximum(50);        progressBar.setBounds(55, 180, 250, 15);        container.add(progressBar);        loadProgressBar();        setSize(370, 215);        setLocationRelativeTo(null);        setVisible(true);    }    private void loadProgressBar() {        ActionListener al = new ActionListener() { public void actionPerformed(java.awt.event.ActionEvent evt) {     count++;     progressBar.setValue(count);     System.out.println(count);     if (count == 300) {         createframe();         execute.setVisible(false);//swapped this around with timer1.stop()         timer1.stop();     } } private void createframe() throws HeadlessException {     Jframe frame = new Jframe();     frame.setSize(500, 500);     frame.setDefaultCloseOperation(Jframe.EXIT_ON_CLOSE);     frame.setVisible(true); }        };        timer1 = new Timer(50, al);        timer1.start();    }    public static void main(String[] args) {        execute = new SplashScreen();    }};

我想将计数器绑定到文件加载，因此，在加载文件时，将加载进度，直到加载文件，然后进度完成，并且初始屏幕消失。

您应该查看一下，
