hi I was wondering, how can I make a variable declared inside main function visible to all functions in Java ? (I dont want to take arguments) for example: public class example { public static void main (String arg[]) { double examp; function (); } public static void function (); { examp = 400.44; } } Thaaanks.

While you are explaining this, i have a question. What does transient mean? And I''m also not quite sure about protected.
Thanks..

Variables marked as transient are not saved when serialising a class, so are usually volatile or calculated from the other data (such as the length of a list).

Protected vars are only accessible to the owning class and any inherited classes.

99 times out of 100, when you think you "need" global access to a single variable, you should re-think your design methodology, not try to force it to happen.

The best advice for global OBJECTS would be to use Singletons.
