The Sun tutorial should cover it pretty nicely: http://java.sun.com/docs/books/tutorial/uiswing/components/frame.html

Keep that Swing tutorial trail bookmarked because there is a wealth of info and demo code on using the various components.

This is another good source for small code snippets demonstrating all kinds of things in Java:
http://www.exampledepot.com/index.html

It only covers Java 1.4, so newer language features in 1.5 and 1.6 will be missing, but most of it is still very relevant.

   {
        StringTokenizer st = new StringTokenizer(text,"|");
            String bu = st.nextToken();  
            String ro = st.nextToken();
            int si = Integer.parseInt(st.nextToken()); 


    char chr =text.charAt(0);
    boolean test1=Character.isUpperCase(chr);
    boolean test2=Character.isDigit(chr);




        if(test1==true || test2==true)
        {
        for (int i = 1;i < text.length();i++) 
            {
        if(Character.isDigit(text.charAt(i))==true)

            }//for
        }//if
        return true;
        else
            return false;

You are better off using a regular expression pattern for things like that. Here's a tutorial link: http://java.sun.com/docs/books/tutorial/essential/regex/
