Producer and Consumer Model

The producer produces one product, the consumer consumes one, the producer waits for the consumer to consume before producing, and the consumer waits for the producer to produce before consuming.

-----------------------
package com.tangkuo.thread.producer.cn;

public class Box {
private int value;//used to store the produced products
//The flag of whether it can be produced, true (can be consumed, cannot be produced), false (can be produced, cannot be consumed)
private boolean avaliable = false;

public synchronized void put(int value){//producer
while(avaliable == true ){
try {
wait();
} catch (InterruptedException e) {
e.printStackTrace();
}
}

avaliable = true;
notifyAll();//Notify all threads waiting for shared resources
this.value = value;
}

public synchronized int get(){//Consumer
while(avaliable == false){
try {
wait();
} catch (InterruptedException e) {
e.printStackTrace();
}
}
avaliable = false;
notifyAll();
return this.value;
}

}

package com.tangkuo.thread.producer.cn;

try {

} catch (InterruptedException e) {
e.printStackTrace();
