If you writestatic public voidinstead ofpublic static voidthen it is perfectly OK. Your Java program will compile and run successfully. It doesn't really make any difference as long as method name comes last and return type of method comes second last. It is generally a co...

(except default and static methods), and all fields are public , static , and final . we can achieve abstraction, multiple inheritances, and loose coupling in java using interfaces. abstraction: the interface reveals only the essential information needed to invoke the method, whereas the ...

and define methods that every subclass should implement and then if there are some methods that only certain subclass should implement, we can extend the base interface and create a new interface with those methods. The subclasses will have the option to chose between the base interface or the ...
