线程池核心代码：

package ThreadPoolTest;

import java.util.ArrayList;
import java.util.List;
import java.util.concurrent.BlockingDeque;

import java.util.concurrent.ForkJoinWorkerThread;
import java.util.concurrent.LinkedBlockingDeque;
import java.util.stream.IntStream;

public class ThreadPool {
    private static final int SIZE = 5;
    private BlockingDeque<Runnable> workQueue;
    private List<WorkThread> workThreads = new ArrayList<WorkThread>();

    public ThreadPool(int poolSize, BlockingDeque<Runnable> workQueue) {
        this.workQueue = workQueue;

        IntStream.range(0, poolSize).forEach((i)-> {
            WorkThread workThread = new WorkThread();
            workThread.start();
            workThreads.add(workThread);
        });
    }

    public ThreadPool(int poolSize)
    {
        this(poolSize, new LinkedBlockingDeque<>(SIZE));
    }

    public void execute(Runnable task) {
        try {
            workQueue.put(task);
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
    }

    class WorkThread extends Thread {
        @Override
        public void run() {
            while (true) {
                try {
                    Runnable workTask = workQueue.take();
                    workTask.run();
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }
            }
        }
    }
}

测试代码：

package ThreadPoolTest;
import java.util.stream.IntStream;

public class ThreadPoolTest {
    public static void main(String[] args) {
        ThreadPool threadPool = new ThreadPool(10);
        IntStream.range(0, 10).forEach((i)->{
            threadPool.execute(()->{
                System.out.println(Thread.currentThread().getName() + "---->>Hello ThreadPool");
            });
        });
    }
}
