java多线程编程

java多线程简单Demo

;

classMythreadimplementsRunnable{

privateThreadt;

privateStringthreadName;

Mythread(Stringname){

threadName=name;

n("Creating"+threadName);

}

publicvoidrun(){

n("Running"+threadName);

try{

for(inti=5;i>0;i--){

n("Thread:"+threadName+","+i);

//让线程睡眠⼀会

(50);

}

}catch(InterruptedExceptione){

n("Thread"+threadName+"interrupted.");

}

n("Thread"+threadName+"exiting.");

}

publicvoidstart(){

n("Starting"+threadName);

if(t==null){

t=newThread(this,threadName);

();

}

}

}

publicclassTestThr{

publicstaticvoidmain(Stringargs[]){

Mythreadt1=newMythread("Thread-1");

();

Mythreadt2=newMythread("Thread-2");

();

}

}

构建和运⾏情况如下；

在java中可有两种⽅式实现多线程,⼀种是继承Thread类,⼀种是实现Runnable接⼝；
