这是一个简单的ProgressBar演示程序

package test;

import java.awt.BorderLayout;
import javax.swing.JFrame;
import javax.swing.JProgressBar;

public class ProgressBarDemo {

    JFrame frame;
    JProgressBar progressBar;

    public ProgressBarDemo() {
        frame = new JFrame("ProgressBarDemo");
        frame.setSize(400, 400);
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        progressBar = new JProgressBar();
        progressBar.setValue(40);
        frame.getContentPane().add(progressBar,BorderLayout.SOUTH);
        frame.setVisible(true);
    }

    public static void main(String[] args) {
        new ProgressBarDemo();
    }

}
