Hi Lakshmi,
From the JLS Spec:
2.8.2 Class Modifiers
A class declaration may include class modifiers. A class may be declared coderanch, as discussed in �2.7.4.
An abstract class is a class that is incomplete, or considered incomplete. Only abstract classes may have abstract methods (�2.10.3),that is, methods that are declared but not yet implemented.
A class can be declared final if its definition is complete and no subclasses are desired or required. Because a final class never has any subclasses, the methods of a final class cannot be overridden in a subclass. A class cannot be both final and abstract, because the implementation of such a class could never be completed.
A class can be declared strictfp to indicate that all expressions in the methods of the class are FP-strict (�2.18), whether or not the methods themselves are declared FP-strict.
A class is declared public to make its type available to packages other than the one in which it is declared. A public class is accessible from other packages, using either its fully qualified name or a shorter name created by an import declaration (�2.7.2), whenever the host permits access to its package. If a class lacks the public modifier, access to the class declaration is limited to the package in which it is
declared.
Regards,
Manfred.
