线程的各种状态如上图所看到的。

对于wait/notify的測试，我将会留到 生产者消费者模式中实现。

对于join、interrupt的測试例如以下：

package com.huan;public class ThreadTest {		public static void main(String[] args) throws Exception{//		joinTest();		interruptTest();	}		public static void joinTest(){		new Thread(){			@Override			public void run() {				Thread t1 = new Thread(){					@Override					public void run() {						try {							Thread.sleep(3000);							System.out.println("//t1 thread");						} catch (InterruptedException e) {							System.out.println("//sleep interrupted");						}					}				};				t1.start();				try {					t1.join();				} catch (InterruptedException e) {					System.out.println("//join interrupted");				}				System.out.println("//out thread");			}		}.start();				//t1 thread		//out thread	};		public static void interruptTest(){		new Thread(){			@Override			public void run() {				Thread t1 = new Thread(){					@Override					public void run() {						try {							Thread.sleep(3000);							System.out.println("//t1 thread");						} catch (InterruptedException e) {							System.out.println("//sleep interrupted");						}					}				};				t1.start();				System.out.println("//out thread");				t1.interrupt();			}		}.start();		//out thread		//sleep exception	};	}
