说明

有两种方法

方式一：execute()

启动一个线程，没有返回值

例子

package ThreadPool;

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

public class StartThread1 {
    public static void main(String[] args) {
        ThreadPoolExecutor threadPoolExecutor = new ThreadPoolExecutor(
                1,
                1,
                10,
                TimeUnit.SECONDS,
                new LinkedBlockingQueue(1)
        );

        threadPoolExecutor.execute(new MyRun("1"));

        threadPoolExecutor.shutdown();
    }
    static class MyRun implements Runnable {
        String name;

        public MyRun(String name) {
            this.name = name;
        }

        @Override
        public void run() {
            System.out.println(name+"--开始");
            try {
                Thread.sleep(3000);
            } catch (InterruptedException e) {
                throw new RuntimeException(e);
            }
            System.out.println(name+"--结束");
        }
    }
}

方式二：submit()

启动一个线程，有返回值

应用场景： 启动线程，执行完毕后，要获取执行结果。
