    在子线程进行完成进度

    package test.object;

import java.awt.FlowLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

import javax.swing.Box;
import javax.swing.JCheckBox;
import javax.swing.JFrame;
import javax.swing.JProgressBar;
import javax.swing.Timer;
import javax.swing.event.ChangeEvent;
import javax.swing.event.ChangeListener;

public class TextMain {

        JProgressBar jProgressBar = new JProgressBar(JProgressBar.HORIZONTAL, 0, 100);

        new Thread(simLaterActivity).start();
        // 设置一个定时任务
        Timer timer = new Timer(200, new ActionListener() {

            @Override
            public void actionPerformed(ActionEvent e) {
                // 当前完成量设置给进度条
                int current = simLaterActivity.getCurrent();
                jProgressBar.setValue(current);

            }
        });
        timer.start();

                if (value == simLaterActivity.getAmout()) {
                    timer.stop();
                }
            }
        });

    }

    private class SimLaterActivity implements Runnable {
        // 当前任务的完成量
        // 任务总量
        private int amout;
        // volatile设置后该线程修改后其他线程可以立即查看到该结果
        private volatile int current;

        public SimLaterActivity(int amout) {

        }
    }

    public static void main(String[] age) {
        new TextMain().init();

    使用BoundedRangeModel进行实现

    package test.object;

        JCheckBox jCheckBox = new JCheckBox("不确定进度");
        JCheckBox jCheckBox2 = new JCheckBox("不绘制边框");

        JProgressBar jProgressBar = new JProgressBar(JProgressBar.HORIZONTAL, 0, 100);
        // 获取进度条数据的模型对象
        BoundedRangeModel model = jProgressBar.getModel();

        // 处理复选框的点击行为
        jCheckBox.addActionListener(new ActionListener() {

            @Override
            public void actionPerformed(ActionEvent e) {
                // 获取一下复选框有没有选中
                boolean selected = jCheckBox.isSelected();
                // 设置当前进度条不确定进度
                jProgressBar.setIndeterminate(selected);
                // 进度百分比是否展示
                jProgressBar.setStringPainted(!selected);
            }
        });
        jCheckBox2.addActionListener(new ActionListener() {

            @Override

                // TODO Auto-generated method stub
                boolean selected = jCheckBox2.isSelected();
                jProgressBar.setBorderPainted(selected);
            }
        });
        jProgressBar.setStringPainted(true);
        jProgressBar.setBorderPainted(true);

        Box createVerticalBox = Box.createVerticalBox();
        createVerticalBox.add(jCheckBox);
        createVerticalBox.add(jCheckBox2);
//      jFrame.add(createVerticalBox, BorderLayout.CENTER);

        jFrame.setLayout(new FlowLayout());
        jFrame.add(createVerticalBox);
        jFrame.add(jProgressBar);
        jFrame.pack();
        jFrame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        jFrame.setVisible(true);
//      // 开启子线程模拟耗时操作
        SimLaterActivity simLaterActivity = new SimLaterActivity(jProgressBar.getMaximum());
        new Thread(simLaterActivity).start();
        // 设置一个定时任务
        Timer timer = new Timer(200, new ActionListener() {

            @Override
            public void actionPerformed(ActionEvent e) {
                // 当前完成量设置给进度条
                int current = simLaterActivity.getCurrent();
//              jProgressBar.setValue(current);
                model.setValue(current);

            }
        });
        timer.start();

        // 给进度条监听任务的变化
        model.addChangeListener(new ChangeListener() {

            @Override
            public void stateChanged(ChangeEvent e) {

                int value = model.getValue();
                if (value == simLaterActivity.getAmout()) {
                    timer.stop();
                }
            }
        });

    }

    private class SimLaterActivity implements Runnable {
        // 当前任务的完成量
        // 任务总量

        // volatile设置后该线程修改后其他线程可以立即查看到该结果
        private volatile int current;

        }
    }

    public static void main(String[] age) {

    ProgressMonitor进度条对话框
