Question to the experts? about saving and retrieving numbers

Question

Question
is there a java method to store a number in the memory and recall it
like M+ and M- in the Microsoft Calculator?
when the M+ button is clicked it store the numbers
When M- button is clicked it recalls the number
lets say ive used
i.e using the String s method which is straight forward
actionPerformed Event e blaah blah blah
//add your handling code here
   String s;
        intA;
        double PhoneNumber;
        s=txtA.getText();
       A=Integer.parseInt(s);
       PhoneNumber= (double)Math.round(A);
       s=String.valueOf(PhoneNumber);
      txtRexhaul.setText(s);now when the M+ button is clicked it stores both the values in "txtA" and "PhoneNumber"
and when the M- button is clicked it recalls the stored numbers and sets it back
using the .setText("") method in "txtA" and "PhoneNumber"
is this possible ?
Solutions are appreciated thanks again

Answer 1

oh ok
lets use stack then ilike node
if it will work just like storing numbers on a calculator M+ and M- functions this is a stack method
class Node {
   String item;
   Node next;
Node first  = new Node();
Node second = new Node();
first.item  = "1222441"; // Clients phone number lets say mine Rexhaul Cartier
second.item = "33322211"; // Clients phone number lets say yours
Node old first=first;
first=first.next; //when the M- button is clickedi get stuck after this i need to simplify this thats where your expertise comes in,
example of a calculator lets say a standard has a Store Button M+ and a recall Button M-
with the String S method as mentioned earlier
when the M+ button is clicked it stores both Textfield "A" and TextField "RexhaulCartier"
when the M- button is clicked it recalls the stored number just like setText(); to the selected textFields
let me simplify this i.e ?---> A // what goes into A
A=1// you type the value
1(store)---> A // stores 1 in variable A when M+ button is clicked
RCL A// recall what was stored in variable A by clicking M- button
A= 1
you get the picture?
i.e if you use Microsoft OS i.e Vista Xp 2000 etc run the calculator in accessories youll see what i mean
when you want to store the answer you press the M+ button when you want to recall it you press M- it displays the stored answer thanks for your time to help me out i really appreciate your help p....
