这里面包含了一百多个JAVA源文件

LinkedList stack = new LinkedList();
    
    // Push on top of stack
    stack.addFirst(object);
    
    // Pop off top of stack
    Object o = stack.getFirst();
    
    // If the queue is to be used by multiple threads,
    // the queue must be wrapped with code to synchronize the methods
    stack = (LinkedList)Collections.synchronizedList(stack);
