java - Reversed method does nothing to stack -

this method supposed return copy of current stack items reversed.

public linkedstack<e> reversed() {     linkedstack<e> that= new linkedstack<e>();     if(this.isempty()==true){         return this;     }     else{         while(this.isempty())//changed this.isempty()==true             {             node<e> snode=this.top;             that.push(snode.getdata());             this.pop();             snode=snode.getlink();                     /*                       that.push(pop()); works                     */              }         return that;         }     } 

update ok 1 of answers seems bring me closer solution. works stack created in method. problem i'm having linking stack can return copy of this stack. i'm using linked stack.

why not

while(!isempty()) {    revertstack.push(pop()); } 

at same time @ original loop particularly first line see may causing problems
