java classes

  Asked By: Trupti    Date: Dec 03    Category: Java    Views: 535
  

I am learning Java.
Could anyone pls let me know the following:

I find that the appropriate package should be selected for a
particular class to be used in a program and also choose the
appropriate class as a superclass.

I want to know how is it possible to know that a particular belongs
to the package and also how to know that any superclass can be used
in my program.

if u r using any popular ide for ur development that will solve ur problem

ex. if u r using any class  without importing its package  it will raise u an
alert with the package name to import. is it ok?

(best ide for java  development is Intellij from jetbrains, using lower ram)

take a look at Reflection, maybe you can resolve your problem with that:
java.sun.com/.../index.html
