利用Lambda表达式创建新线程案例

代码

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!");    
 }
}

运行

Hello main
Done!
Hello Thread-0

补充知识：java_Thread多线程创建和lambda

我就废话不多说了，大家还是直接看代码吧~

//----------------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());
}
}
