博客围绕Java多线程与并发编程展开，涉及thread相关知识。多线程能提升程序性能，并发编程可处理多个任务。Java在多线程和并发编程方面有强大功能和丰富工具。

public class Run implements Runnable{
    @Override
    public void run() {
        String threadName = Thread.currentThread().getName();
        System.out.println("当前线程 "+threadName);
    }

    public static void main(String[] args) {
        new Thread(new Run()).start();
    }
}

public class Run extends Thread{
    @Override
    public void run() {
        String threadName = Thread.currentThread().getName();
        System.out.println("当前线程 "+threadName);
    }
    public static void main(String[] args) {
        new Thread(new com.kongdechang.stu.Run()).start();
    }
}

public class Run {
    public static void main(String[] args) {
        new Thread(()->{
            String threadName = Thread.currentThread().getName();
            System.out.println("当前线程 "+threadName);
        }).start();
        new Thread(new Runnable() {
            @Override

            return threadName;
        };
        //获取线程池,执行线程数量
        ExecutorService es = Executors.newFixedThreadPool(2);
        //提交线程任务
        es.submit(new Run());
        es.submit(new Run());

        Future<String> future = es.submit(callable);
        //关闭线程池
        es.shutdown();
        System.out.println(future.get());
    }
