Producer Consumer problem - Solution using Semaphore in Java

ProdCon.java

import java.util.concurrent.Semaphore;

class Queue {
  int value;

  static Semaphore semProd = new Semaphore(1); //Producer is first getting lock on producer semaphore
  
  static Semaphore semCon = new Semaphore(0);
  

  void get() {
    try {
      semCon.acquire();
    } catch (InterruptedException e) {
      
    }
    System.out.println("Got: " + value);
    semProd.release();
  }

  void put(int n) {
    try {
      semProd.acquire();
    } catch (InterruptedException e) {
      
    }

    this.value = n;
    System.out.println("Put: " + n);
    semCon.release();
  }
}

class Producer implements Runnable {
  Queue q;

  Producer(Queue q) {
    this.q = q;
    new Thread(this).start();
  }

  public void run() {
    for (int i = 1; i < 11; i++)
      q.put(i);
  }
}

class Consumer implements Runnable {
  Queue q;

  Consumer(Queue q) {
    this.q = q;
    new Thread(this).start();
  }

  public void run() {
    for (int i = 1; i < 11; i++)
      q.get();
  }
}

public class ProdCon {
  public static void main(String args[]) {
    Queue q = new Queue();
    new Consumer(q);
