The case of a missing value of an object...

Question

I have set up a put and get method so as to synchronize two of my threads the synchronization works fine but the value of the object myteriously when i trying to again get the value after i have set it disappears. Could someone please help me...
Here are some part of my code
private Object value;
      public RequestArrayGetSet(){
           request = null;
public synchronized void put(Object value){
           print("in put() - Entering!");
           while(request !=  null){
                try{
                     print("in put() - occupied, about to wait()");
                     wait();
                     print("in put() - notified, back from wait()");
                }catch(Exception e){
                     e.printStackTrace();
           value = value;
           print("in put() - filled the slot, about to notifyAll()");
           System.out.println(value);
           notifyAll();
           print("in put() - leaving");
      public synchronized Object get(){
           print("in get() - Entering");
           while(request == null){
                try{
                     print("in get() - empty - about to wait()");
                     wait();
                     print("in get() - notified, back from wait()");
                }catch(Exception e){
                     e.printStackTrace();
           Object obj = value;
           System.out.println(obj);
           request =  null;
           print("in get() - emptied the slot, about to notifyAll()");
           notifyAll();
           print("in get() - leaving");
           return  obj;
      }Hope some of you can help thanks!

Answer 1

value = value;Oh, so you have one of those new compilers that reads your mind and knows which value is which in that statement, huh?
Lucky.
The rest of us are stuck doing this.value = value;so that the compiler can distinguish the member variable from the method parameter.
