Examples of Java threading operations

One: Example of threading operations ( 1 )

Package com.cloud.day6;

public class Demo1 {

publicstatic void Main (string[] args) {

Mythreadmt1=new MyThread ("Thread A", 1000);

Mythreadmt2=new MyThread ("Thread B", 2000);

Mythreadmt3=new MyThread ("Thread C", 3000);

Mt1.start ();

Mt2.start ();

Mt3.start ();

}

}

Class MyThread extends thread{

Privateint time;

Publicmythread (String name,int time) {

Super (name);

This.time=time;

}

Publicvoid Run () {

try{

Thread.Sleep (This.time);

}catch (Exception e) {

E.printstacktrace ();

}

System.out.println (Thread.CurrentThread (). GetName () + ", hibernate" +this.time);

}

}

Two: Example of threading operations ( 2 )

Package com.cloud.day6;

public class Demo1 {

publicstatic void Main (string[] args) {

Mythreadmt1=new MyThread ("Thread A", 1000);

Mythreadmt2=new MyThread ("Thread B", 2000);

Mythreadmt3=new MyThread ("Thread C", 3000);

Newthread (MT1). Start ();

Newthread (MT2). Start ();

Newthread (MT3). Start ();

}

}

Class MyThread implements runnable{

Privatestring name;

Privateint time;

Publicmythread (String name,int time) {

This.name=name;

This.time=time;

}

Publicvoid Run () {

try{

Thread.Sleep (This.time);

}catch (Exception e) {

E.printstacktrace ();

}

System.out.println (this.name+ ", dormant" +this.time);

}

}

Three: Sync ticket problem in thread

Package com.cloud.day6;

public class Demo1 {

publicstatic void Main (string[] args) {

Mythreadmt1=new MyThread ();

Threadt1=new Thread (MT1);

Threadt2=new Thread (MT1);

Threadt3=new Thread (MT1);

T1.start ();

T2.start ();

T3.start ();

}

}

Class MyThread implements runnable{

Privateint ticket=5;

Publicvoid Run () {

for (inti=0;i<100;i++) {

This.sale ();

}

}

publicsynchronized void Sale () {

if (ticket>0) {

try{

Thread.Sleep (3000);

}catch (Interruptedexception e) {

E.printstacktrace ();

}

System.out.println ("sold a ticket, left the ticket:" + (--ticket) + "Zhang");

}

}

}

Four: Thread deadlock problem

That is, two threads are waiting for each other to execute

Packagecom.cloud.day6;

Publicclass Demo2 {

public static void Main (string[] args) {

MyThread1 mt1=new MyThread1 ();

MyThread1 mt2=new MyThread1 ();

Mt1.flag=true;

Mt2.flag=false;

Thread th1=new thread (MT1);

Thread th2=new thread (MT2);

Th1.start ();

Th2.start ();

}

}

classzhansan{

public void Say () {

System.out.println ("Zhang San: you draw me, I give you the book");

}

public void get () {

System.out.println ("Zhang San Get Painted");

}

}

classlisi{

public void Say () {

SYSTEM.OUT.PRINTLN ("John Doe: You give me books, I draw for You");

}

public void get () {

SYSTEM.OUT.PRINTLN ("John Doe got the book");

}

}

CLASSMYTHREAD1 Implements runnable{

private static Zhansan zs=new Zhansan ();

private static Lisi is=new Lisi ();

public Boolean flag=false;

@Override

public void Run () {

if (flag) {

Synchronized (ZS) {

Zs.say ();

try {

Thread.Sleep (500);

} catch (Interruptedexception e) {

E.printstacktrace ();

}

Synchronized (IS) {

Zs.get ();

}

}

}

else{

Synchronized (IS) {

Is.say ();

try {

Thread.Sleep (500);

} catch (Interruptedexception e) {

E.printstacktrace ();

}

Synchronized (ZS) {

Is.get ();

}

}

}

}

}
