Declaring Global Variables in Java

If you are coming from C or C++ background, you must miss declaring Global variables in Java.

You can get the same functionality in Java by declaring a class and making variables public and static. Here is the Code:

 public class GlobalDataStore {public static long globalData = 0;}

Other classes can access variables as GlobalDataStore.globalData. There will be only one value of globalData as it is declared static.
