一个方法的执行过程以进度条来显示它的执行进度

[lijiemissfei]

我要调用一个方法。这个方法执行时间可能时间会有点长。执行完后再弹出界面。

final JProgressBar aJProgressBar = new JProgressBar(0, 100); 
		aJProgressBar.setIndeterminate(true);   
		JFrame progressFrame = new JFrame("正在加载资源");
		JLabel label = new JLabel("",JLabel.CENTER);
		progressFrame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
		Container contentPane = progressFrame.getContentPane();    
		contentPane.add(aJProgressBar, BorderLayout.NORTH);
		label.setText("请稍候。。。");
		contentPane.add(label, BorderLayout.CENTER);
		progressFrame.setSize(300, 100);
		progressFrame.setVisible(true);

蛋疼。你是说没重写run方法吗？你没仔细看。
忘记结账了。谢谢各位同仁了
