Stack Thread Safe-Autobloccante

[raffylam]

Salve ragazzi
Qualcuno potrebbe aiutarmi ad implementare uno Stack Thread Safe-Autobloccante?Io ho provato così ma non so se sia giusto o meno

public class Stack<Info> { 
private LinkedList<Info> s; 
private int capacity;
 public synchronized int getCapacity() {
 return capacity; 
} 
public Stack(int capacity) { 
this.capacity = capacity; 
this.s = new LinkedList<Info>(); 
} 
public synchronized boolean isEmpty(){ 
return s.size() == 0; 
} 
public synchronized boolean isFull(){ 
return s.size() == capacity; 
} 
public synchronized int size(){ 
return s.size(); 
} 
public synchronized void push(Info i) { 
while(isFull()){ 
try { s.wait(); 
} catch (InterruptedException ex) { } 
}
 s.add(i); 
s.notifyAll();
 } 
public synchronized Info pop(){ 
while(isEmpty()){ 
try { s.wait(); 
} catch (InterruptedException ex) { } 
} 
s.notifyAll(); 
return s.removeLast(); 
} 
public synchronized void reset(){
 s.removeAll(s); 
} 
}
