There is a public final class Objects in Java 7 that extendes the java.lang.Object base class.

Will this by default be the base class like or do we need to call the method on "Objects" class and call the corresponding methods?

No. Nothing changes. The Objects class is simply an utility class. It has only static methods, it's in the util package, and does what ObjectUtils from commons-lang is doing.

Objects is final and it extends Object giving you null safe utilities.
