Go4Expert - [typical]toPrefix method

Dear all
I am new register member

As I am writting a program which need to convert an expression from infix/postfix to prefix

This case with some condition where it can specific '(' and ')' operator and two digits value.

I prefer the method will be like this

Code:

public static String toPrefix(String inputfix) // which inputfix can be infix or postfix{



...

return prefix;

}

Could it be using Stack?

I am green
Thx a lot..hope for reply..
