Hope you guys can help me thanks....:confused:

What you have tried so far?

The thing you have to do is, take each element and compare it with the whole list you have. While you find the same in a different location, increment the count by one.

Not much clear what you want to know. I guess you are talking about graphics, or UI design. In Java for UI designing use Swing or AWT packages. Those are standard packages with the JDK version. What's the connection with Excel and graphic. If you want to write something to an Excel workbook, nothing to do with UI directly. You have to do it in background, while the foreground is the UI.

Well the thing here reagarding excel is that for example i have 4 basic math problems add, subtract, multiplication, ok so lets say i do 2 operations for each basic math problem 2 add, 2 subract, 2 multiply and the results wich are going to be 6 results need to be in a graph basic one does not need to be extreamly high graphical you know the bars but the issue is i cant use Excel or atleast use it but with discresion you know hidden any ideas on how to do that??

Do you mean that the graphics/bars can be done on the command prompt, sorta like the following?

Code:

---

add      ********
subtract  ****
multiply  ************
divide    ******

Ok, first of all you must have a clear approach for the mathematical solution. I'm not clear what you exactly want, the way Chris explain?
