calculator program

[cindyg919]

i am writing a program and i need help with it please. the program is:
write a simple calculator. each valid command for this calculator should consist of an operation followed by an operand. this is an accumulator-based calculator, meaning, each arithmetic operator only takes a single number. the original accumulator value is 0 and every successive operation will be on this value.the calculator should display the accumulator value after each operation.
using these keys: + add, - subtract, * multiply,
/divide, ^ power, q quit
i want the results to come out like this:
+5
result so far is 5.0
^2
result so far is 25.0
/ 2
result so far is 12.5
q 0
final result is 12.5

*********ARRAYS CANNOT BE USED IN THIS PROGRAM*************

Why don't you start writing the code and when you get to a point where you are having trouble, ask a specific question. It does you no good to have someone here write the entire program for you. Here I'll start you off:

public class Calculator {
   
   public void static main(String args []) {
      
      /* 
       * Most of your code will go 
       * in this method.  You will 
       * probably be using a switch
       * statement nested inside a
       * while loop.
       */ 

   }

   /* 
    *  May want to declare some static 
    *  instance variables here 
    */
}

That should be enough to get you started. Write back with specific questions if you need more help.
