Java线程的创建

    创建Java线程有两种方法：

//子类化Thread
public class TestThread extends Thread{
	
	public void run(){
		System.out.println("Test Thread.");
	}
	
	public static void main(String[] args) {
		Thread t = new TestThread();
		t.start();
		
	}

}

//方法二：提供Runnable对象
public class TestRunnable implements Runnable {

	public void run() {
		System.out.println("Test Runnable");
	}

	public static void main(String[] args) {
		TestRunnable r = new TestRunnable();
		Thread t = new Thread(r);
		t.start();
	}

}

public interface Runnable {
	
	public abstract void run();
}

//一般来说，要创建一个线程，让这个类实现Runnable接口是比较好的选择
