java制作程序启动进度窗口

运行效果如下：

代码如下：

import java.awt.BorderLayout;
import java.awt.Color;
import java.awt.Dimension;

import javax.swing.ImageIcon;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JProgressBar;
import javax.swing.JWindow;

public class MyWindowTest {
	public MyWindowTest() {
		ImageIcon image = new ImageIcon("login.jpg"); 
		JLabel label = new JLabel(image);
		
		JProgressBar bar = new JProgressBar(1, 100);
		bar.setStringPainted(true); //描绘文字
		bar.setString("加载程序中,请稍候......");  //设置显示文字
		bar.setBackground(Color.white);  //设置背景色		
		
		JWindow win = new JWindow();	 
		win.add(label,BorderLayout.CENTER);
		win.add(bar,BorderLayout.SOUTH);  //增加进度条到容器上
		
		win.pack();      //注意先要执行这段代码再设置窗口位置，否则窗口位置将会显示不正确（窗口适应组件）	
		//设置窗口显示的位置
		Dimension screen = win.getToolkit().getScreenSize();
		win.setLocation((screen.width-win.getSize().width)/2,(screen.height-win.getSize().height)/2);
		win.show();
		
		myRun(bar, win);
	}
	
	public void myRun(JProgressBar bar,JWindow win){
		 try {
		      for (int i=0;i<100;i++){
		        Thread.sleep(100); //线程休眠
		        bar.setValue(bar.getValue()+1); //设置进度条值
		      }
		    }
		    catch (Exception ex) {
		      ex.printStackTrace();
		    }
		    win.dispose(); //释放窗口
		    JFrame frame = new JFrame();
		    frame.setSize(300, 300);
		    frame.setLocationRelativeTo(frame.getOwner());
		    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
		    frame.show();
	}
	
public static void main(String[] args) {
	MyWindowTest windowt = new MyWindowTest();
	}
}
