Description: TimezoneDateTime class has one method as createFormattedDateTime that uses two parameters to give Date, Time, or Both for specific location on Earth to the user in stylized format. I coded 26 different Date and Time formats and you may add much more by following my structured coding. First Parameter must be a Java Timezone ID such as
Australia/Melbourne
America/Los_Angeles
and second parameter is a number that gives you the selected formatted output from 1 to 26. You may see all available Java Timezone id by using this code

How to Run: I tested all codes on Windows 7 Command Prompt with Java(TM) SE Runtime Environment 6 on my computer. ( you may download it by visiting this link )
You need to create all files and save it in a folder in your computer such as C:\javacodes and compile and run at command prompt as follows. I assumed you saved all files at C:\javacodes
C:\javacodes> javac TimezoneDateTime.java -d c:\javacodes "this statement compiles the class and creates TimezoneDateTimePKG package"
C:\javacodes> javac Timezone.java "compiles the Main class"
C:\javacodes> Java Timezone "and this statement runs the Timezone.java"
and the result will be

 * Parameter 2 is the Date and Time format style that should be a number from 1 to 26.
 * eg: if I run this method through a for loop with "Australia/Melbourne" Timezone Id,
 * as below
 * 
        for (int counter = 1; counter <= 26; counter++) {
            System.out.println(counter + ") " + tz.createFormattedDateTime("Australia/Melbourne", counter));
        }
