利用Lambda表达式创建新线程案例

public class LamdaDemo
{
  public static void main( String[] args )
  {    
    Runnable task = () -> {
      String threadName = Thread.currentThread().getName();
      System.out.println("Hello " + threadName);
    };
 
    task.run();
    Thread thread = new Thread(task);
    thread.start();
 
    System.out.println("Done!");    
  }
}

Hello main
Done!
Hello Thread-0

//----------------方式一实现Runnable接口----------------
public class TestThread implements Runnable
{
	public static void main(String[] args)
	{
		ThreadPring();
	}
	static void ThreadPring()
	{
		//-------------------------方式二,new一个Runnable()匿名内部类----------------
		Runnable run2=new Runnable()
		{
			@Override
			public void run()
			{
				System.out.println(Thread.currentThread().getName());
			}
		};
		//------------------------方式三,lambda简写,jdk1.8特性----------------
		Runnable run=()->
		{
			System.out.println(Thread.currentThread().getName());
		};
		new Thread(run).start();
		new Thread(run2).start();
		new Thread(new TestThread()).start();
		new myThread().start();
	}
	
	@Override
	public void run()
	{
		try
		{
			//线程休眠3秒
			Thread.sleep(3000);
		} catch (InterruptedException e)
		{
			e.printStackTrace();
		}
		System.out.println(Thread.currentThread().getName());
	}
}
//--------------方式四,继承线程类Thread----------------
class myThread extends Thread
{
	@Override
	public void run()
	{
		System.out.println(Thread.currentThread().getName());
	}
}
