【Java基础学习笔记】Thread+JLabel实现线程

package Thread_Test;

import java.awt.Container;

import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.SwingConstants;

public class Thread_Swing extends JFrame {
	/**
	 *
	 */
	private static final long serialVersionUID = 1L;
	private JLabel jl = new JLabel("hi");
	private static Thread t;
	private int count = 0;
	private Container c = getContentPane();

	public Thread_Swing() {
		// TODO Auto-generated constructor stub
		setBounds(300, 200, 250, 100);
		c.setLayout(null);
		jl.setHorizontalAlignment(SwingConstants.LEFT);
		jl.setBounds(10, 10, 200, 50);
		t=new Thread(new Runnable() {

			public void run() {
				// TODO Auto-generated method stub
				while (count<=200){
					jl.setBounds(count, 10, 200, 20);
					try {
						Thread.sleep(500);
					} catch (Exception e) {
						// TODO: handle exception
						e.printStackTrace();
					}
					count+=4;
					if(count==200){
						count=10;
					}
				}
			}
		});
		t.start();
		c.add(jl);
		setVisible(true);
		setDefaultCloseOperation(EXIT_ON_CLOSE);
	}

	public static void main(String[] args) {
		// TODO Auto-generated method stub
		new Thread_Swing();
	}

}

笔记：利用线程来实现JLabel的循环滚动。

实用runnable接口创建线程步骤：创建Runnable的类——》实例化对象——》写实现方法，即：thread t—— t = new thread（new runnable）——run里面写方法
