1.继承

代码：
package MyThread;

public class Myextends extends Thread{
	public Myextends(String name) {
		super(name);
	}
	public void run() {
		for(int i=0;i<3;i++) {
			System.out.println(this.getName()+"打印信息"+i);
			try {
				Thread.sleep(1000);
			} catch (InterruptedException e) {
				// TODO 自动生成的 catch 块
				e.printStackTrace();
			}
		}
	}
	public static void main(String[] args) {
		Myextends thread1=new Myextends("线程1");
		Myextends thread2=new Myextends("线程2");
		thread1.start();
		thread2.start();
	}
}

2.实现Runnable方法

代码：
package MyThread;

public class MyRunnable implements Runnable{
	String name;
	public MyRunnable(String name) {
		this.name=name;
	}
	public void run() {
		for(int i=0;i<3;i++) {
			System.out.println(name+"打印信息"+i);
			try {
				Thread.sleep(1000);
			} catch (InterruptedException e) {
				// TODO 自动生成的 catch 块
				e.printStackTrace();
			}
		}
	}
	public static void main(String[] args) {
		MyRunnable myrunnable1=new MyRunnable("线程1");
		MyRunnable myrunnable2=new MyRunnable("线程2");
		Thread thread1=new Thread(myrunnable1);
		Thread thread2=new Thread(myrunnable2);
		thread1.start();
		thread2.start();
	}
}

3.优先级

代码：
package MyThread;

public class Myextends extends Thread{
	public Myextends(String name) {
		super(name);
	}
	public void run() {
		for(int i=0;i<3;i++) {
			System.out.println(this.getName()+"打印信息"+i);
			try {
				Thread.sleep(1000);
			} catch (InterruptedException e) {
				// TODO 自动生成的 catch 块
				e.printStackTrace();
			}
		}
	}
	public static void main(String[] args) {
		Myextends thread1=new Myextends("线程1");
		Myextends thread2=new Myextends("线程2");
		thread1.start();
		thread2.start();
	}
}

4.文字移动

代码：
package MyThread;

import java.awt.Font;

import javax.swing.*;
public class MyThreadRmove {
	JFrame f;
	JPanel p;
	JLabel l;
	public MyThreadRmove() {
		f=new JFrame("文字移动");
		p=new JPanel();
		l=new JLabel("模拟字幕移动测试");
		f.setVisible(true);
		f.setSize(600, 400);
		f.add(p);
		p.setLayout(null);
		p.add(l);
		l.setBounds(0, 140, 200, 20);
		l.setFont(new Font("宋体",Font.BOLD,20));
		f.setBounds(450, 200, 600, 400);
	}
	public void f() {
		Thread t=new Thread(new Runnable(){
			public void run() {
				int i=5,j=420;
				while(true) {
					if(i<420) {
						try {
							Thread.sleep(60);
						} catch (InterruptedException e) {
							e.printStackTrace();
						}
						l.setBounds(i, 140, 200, 20);
						i=i+5;
					}
					else if(j>=0) {
						try {
							Thread.sleep(60);
						} catch (InterruptedException e) {
							e.printStackTrace();
						}
						l.setBounds(j, 140, 200, 20);
						j=j-5;
						if(j==0) {
							i=5;
							j=420;
						}
					}
				}
			}
		});
		t.start();
	}
	public static void main(String[] args) {
		MyThreadRmove mtr=new MyThreadRmove();
		mtr.f();
	}
}

5.时钟

代码：
package MyThread;

import java.awt.Font;
import java.text.SimpleDateFormat;
import java.util.Date;
import javax.swing.*;

public class MyTime implements Runnable{
	JFrame f;
	JLabel l;
	public MyTime() {
		f=new JFrame("NowTimes");
		l=new JLabel();
		f.setVisible(true);
		f.setSize(300, 300);
		f.setLayout(null);
		f.add(l);
		f.setBounds(600, 300, 350, 200);
		l.setBounds(10, 60, 320, 20);
	}
	public void run() {
		SimpleDateFormat sdf=new SimpleDateFormat("yyyy年MM月dd日 HH时:mm分:ss秒");
		Font font = new Font("楷体",Font.BOLD,20);
		l.setFont(font);
		while(true) {
			Date date=new Date();
			l.setText(sdf.format(date));
			try {
				Thread.sleep(1000);
			} catch (InterruptedException e) {
				// TODO 自动生成的 catch 块
				e.printStackTrace();
			}
		}	
	}
	public static void main(String[] args) {
