How to modify my Stack.java?????

Question

I want to make my Stack.java doing like this:
stackType<nodeType<elemType>*> stack; //C++
stackType<int> intStack; //C++ code
My Stack.java:
public class Stack {
     TreeNode items[];
     int StackSize;
     int top;
    public Stack(int size)
         StackSize = size;
        items = new TreeNode[size];
        top = -1;
    public boolean empty()
         if(top == -1)
           return true;
        else
          return false;
    public boolean full()
         if(top == StackSize-1)
           return true;
         else
           return false;
    public void push(TreeNode c)
        if(full() == true)
           System.out.println("stack overflow");
        else
            items[++top] = c;
    public TreeNode pop()
         if(empty())
           System.out.println("stack underflow");
        return items[top--];
}

You don't need templates in java, since all java objects derive from java.lang.Object (it isn't possible either). Just use the original Stack (java.util.Stack). To push primitive types, just use the wrapper classes (java.lang.Integer, java.lang.Double...).
