本文介绍了一种自定义线程池的实现方法，通过继承ThreadGroup并利用ThreadPoolExecutor进行任务调度。该线程池支持最大线程数、核心线程数及任务队列大小的配置，并采用丢弃最旧任务的拒绝策略。

package com.geolo.android.tea.system;

import java.util.concurrent.ArrayBlockingQueue;
import java.util.concurrent.ThreadPoolExecutor;
import java.util.concurrent.TimeUnit;

public class MyThreadPool extends ThreadGroup{

	private static MyThreadPool myThreadPool;
	private ThreadPoolExecutor mThreadPoolExecutor;
	private static int number = 0;
	
	public MyThreadPool(String name) {
		 this(Thread.currentThread().getThreadGroup(), name);
	}
	
	public MyThreadPool(ThreadGroup parent, String name) {
		super(parent, name);
		mThreadPoolExecutor =  new ThreadPoolExecutor(2, 4, 3,
				TimeUnit.SECONDS, new ArrayBlockingQueue<Runnable>(3),
				new ThreadPoolExecutor.DiscardOldestPolicy());
	}
	
	public static MyThreadPool getInstance(){
		if(myThreadPool==null){
			number ++;
			myThreadPool = new MyThreadPool(number+"");
		}
		return myThreadPool;
	}
	
	public void Executor(Runnable runnable){
		//mThreadPoolExecutor.execute(runnable);
		mThreadPoolExecutor.execute(runnable);
	}
}
