A Simple calculator

[unixisbest]

Hi all,
I don`t know much about java but i would like to create a simple calculator for complex numbers. Operator and operands will be entered using a keyboard, results will be printed into the standart output.The application will ask user after every computation, if that wants to perform another computation.

Any idea?

try {
        BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
        String str = "";
        while (str != null) {
            System.out.print("> prompt ");
            str = in.readLine();
            process(str);
        }
    } catch (IOException e) {
    }
