コードには何が問題なのですか？スレッドがインターリーブしないのはなぜですか？

Question

class Producer implements Runnable{ //producer job here 
    Vector<Integer> sQueue; 
    public Producer(Vector<Integer> queue) { 
     this.sQueue=queue; 
    } 
    public void run(){ 
     int i=0; 
     try{ 
      synchronized(sQueue){ 
       for(i=0;i<30;i++){ 
        if(sQueue.size()<15){ 
         System.out.println("Producer producing the item:-"+i); 
         sQueue.add(i); 
         sQueue.notifyAll(); 
        } 
        else 
        { sQueue.notifyAll(); 
         sQueue.wait(); 

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

} 
class Consumer implements Runnable{ 
    Vector<Integer> sQueue; 
    public Consumer(Vector<Integer> queue) { 
     this.sQueue=queue; 
    } 
    public void run(){ 
     int i=0; 
     try{ 
      synchronized(sQueue){ 
       while(true){ 
        if(sQueue.size()>0){ 
         System.out.println("Consumer is removing the item:-"); 
         int item=sQueue.remove(0); 
         System.out.println(item); 
         sQueue.notifyAll(); 
         Thread.sleep(1000); 
        } 
        else 
        { 
         sQueue.wait(); 
        } 
       } 
      } 
     } 
     catch(Exception e){ 
      e.printStackTrace(); 
     } 
    } 
} 
public class ProducerConsumerProblem { 
    public static void main(String [] arg){ 
     Vector<Integer> sQueue; 
     sQueue = new Vector<>(15); 
     Producer p=new Producer(sQueue); 
     Consumer c=new Consumer(sQueue); 
     Thread producer=new Thread(p); 
     Thread consumer=new Thread(c); 
     producer.start(); 
     consumer.start(); 
    } 
} 

上記のコードでは、私は、Javaマルチスレッドの助けを借りてプロデューサ消費者の問題をシミュレートしようとしています。私は私が間違っている、生産者スレッドと消費者のスレッドがインターリーブされていない何が起こっているか知らない整数である共有キューとしてSQUEUEを使用しています、ここ

あなたの方法は​​ている私のマシン上で出力されます。 Producerが起動すると、キューのロックが取得され、完了するまで待機しません。 Consumerが起動すると、ロックを取得できるまで待ちます。インターリーブする必要がある場合は、同期させないでください。​​キーワードは具体的にはです。インターリーブを防止します。
