DataPool in servlet 4a

[Peter Gragert]

Dear Marily
I do not understand your 'remark':
======my code==========
> static DataPool passwordInfo = new DataPool();
=========== Marilyns remark=====
Why do you instantiate DataPool? What instance method are you using?
======= end ===========
I just want to have a DataPool only once and it can be created already in the very first beginning such that I can use it without bothering about it in dependent classes (inheritance).

DataPool has static methods. You don't need to instantiate it to use them. Integer.parseInt() is a static method of the Integer class. You don't need to instantiate an Integer to use the method.

Integer theInt = new Integer() ;
theInt.parseInt( args[0] ) ;

is possible, but not necessary.

Thank you for immediate reply.
I now know what you mean and where to look at.
Have a nice weekend!
