If you create a static variable y, then you can surely also create another static variable x.

Can't seem to figure out what the error here is. Can you give more details about the error that you are getting?

[Mohan Patidar]

in My program i have declared two variables x and y.....x is a final static variable and y is only static in inner class.....in inner class we can declare a static final variable but we can not declare static variable why?

[AnujS Sharma]

You can declare both of them.

What is the error that you are getting?

[Campbell Ritchie]

It's in the Java Language Specification.

This is talking about Inheritance.

The code that you have provided does not use inheritance.
