While debugging code Java programmers often use System.out.println(). It is important to write separate message in each System.out.println() so you can understand from the output where the problem lies.
Now it is time-consuming and somewhat tedious to invent new message for each System.out.println() debug message. What if you could call methods which allows you to print the current file name and line number?
That would automatically ensure unique message in every System.out.println(). Also it will help you to immediately pinpoint the offending code. You can copy-paste something like this anywhere in your code (embellish it with more topical information as needed) and be able to pinpoint its location:
I will show the implementation of getLineNumber() below and leave the rest as an exercise:
/** Get the current line number. * @return int - Current line number. */ public static int getLineNumber() { return Thread.currentThread().getStackTrace()[2].getLineNumber(); }
Have you noticed the magic number - 2? Can you explain it?
The best way to suppress unchecked or other warnings is to fix the cause of the warning. However in some rare cases, the warning is incorrect and there is no logical way to solve it without compromising the intended functionality. For such cases there is a simple solution:
Add the following just before the method definition:
@SuppressWarnings("unchecked")
This stops any unchecked warnings from the code within the method.

Windows users are used to formatting and re-installing Windows Vista or Windows XP. But a genuine problem may arise if you lose or forget the product key you are given. Windows don't actually save the key you enter in its crudest form. Its encrypted and hidden inside the registry and you can not hunt it down unless you know how. So you must be wondering, HOW? Here is how.
First download Magical Jelly Bean Keyfinder. Its a freeware open source utility that retrieves your Product Key (cd key) used to install Windows from your registry. It allows you to print or save your keys for safekeeping.
Run the key finder program. Follow any instructions provided by the software.
The numbers and letters displayed by the program represent the Windows Vista product key. The product key should be formatted like xxxxx-xxxxx-xxxxx-xxxxx-xxxxx - five sets of five letters and numbers.
Write this key code down exactly as the program displays it to you for use when reinstalling Windows Vista.
So you got the lost or forgotten product key, right? Keep it safe.
