System.out.println( name.indexOf("M") );
System.out.println( name.indexOf("ter") );
System.out.println( name.length() );
System.exit(0);
}

i dont know if this will help or not. when i try to compile it says
number16:28:cannot find symbol
symbol:variable text
location: class number16
JOptionPane.showMessageDialog( jFrame, name.substring(5, 6)+name.substring(name.length() -3, text.length() ));
