Java notify () wait () synchronized producer and consumer case

Too lazy to write, look directly at the code

Mobile Phone class

/*** Mobile Phone type * Maximum number of phones produced *@authorHWUA **/ Public classshouji{ Public intMax//define container Maximum capacity     Public intCurrentnum;//defining the container's current capacity          PublicShouji (intmax) {         This. Max =Max; Currentnum= 0; }}

Production class

//production of mobile phone class Public classSjphone1Implementsrunnable{ PublicShouji con;  PublicSjphone1 (Shouji con) {//constructor Function         This. con =con; }     Public voidrun () { while(true){//Keep Running            synchronized(Con) {//Phone class lock                if(Con.currentnum < Con.max) {//If the current container is dissatisfied, it can produceCon.notify ();//notify and release the lock after productioncon.currentnum++; System.out.println ("Producers are producing Xiaomi mobile phone 1, the current number of products:" +con.currentnum+ "department"); }Else if(Con.currentnum = = Con.max) {//if the production of mobile phone equals the largest definition of mobile phone market capacitySystem.out.println ("Mobile phone production has been saturated, producers stop production, is waiting for consumption ..."); Try{con.wait ();//suspend production and release locks}Catch(interruptedexception e) {e.printstacktrace (); }                }//if else if}//SYN Executes the synchronization block release lock, output two consecutive times the producer is because: after releasing the lock, if there is no waiting for the thread, then the first thread to execute the synchronization block to execute it                         Try{Thread.Sleep (100);//adjust the producer frequency, too quickly and easily sudden death ~ ~}Catch(interruptedexception e) {e.printstacktrace (); }//Try}// while    }}

Consumer Products

//Consumer Products Public classSjphone2Implementsrunnable{ PublicShouji con;  PublicSjphone2 (Shouji con) {//constructor Function         This. con =con; }     Public voidrun () { while(true){//Keep Running            synchronized(Con) {//Mobile phone Lock                if(Con.currentnum > 0) {//when you have a cell phone,Con.notify ();//Buy your phone and release the lockcon.currentnum--; System.out.println ("Consumers are consuming Xiaomi mobile phones sell 1, the current number of products:" +con.currentnum+ "department"); }Else if(Con.currentnum = = 0) {//If you don't have a cell phoneSystem.out.println ("The phone has been bought, consumers stop spending, is waiting for production ..."); Try{con.wait ();//suspend consumption and release locks}Catch(interruptedexception e) {e.printstacktrace (); }                }//else if}//syn                         Try{Thread.Sleep (140);//adjust the consumer frequency, too fast easy to die ~ ~}Catch(interruptedexception e) {e.printstacktrace (); }//Try}// while}//Run}

Test class Main

/*** Test Class*/ Public classdome01{ Public Static voidMain (String args[]) {Shouji container=NewShouji (5);//define the maximum definition of mobile phone market capacity, here is 5Sjphone1 sj1 =NewSjphone1 (container);//the number of mobile phones in the box is synchronized, so the phone object reference is passed as a parameter to the producer and consumerSjphone2 sj2 =NewSjphone2 (container);//Ibid .//Start production consumption mode        NewThread (sj1, "production"). Start (); NewThread (Sj2, "consumption"). Start (); }}

Remember that the lock object must be

Constructor  Correspondence

Shouji class

The same object, or the thread will run, no rules, must be locked up
