Answer / anjani kumar jha
public is used because from anywhere u r able to call ur
main method
static-static is the entry point of main function which is
executing by jvm(at run time) in other word signature of
the main function.

Answer / psreddy
public access modifier we declared then that class visible
to every where and access to any where
bcoz if we write any number business logic classes but
we have to write only one execution logic class for all
these business logic classes
that is why always execution logic class as public
and also there is need of writing static key word
bcoz the execution logic executes only once
other wise we will get runtime exeption

Answer / aravinda reddy
1) Public access modifier specifies class declared can be
accesses from anywhere
2) where as static refers with out creating instance of the
class JVM should access the main class while executing.
3) void specified main function should not return any value

Answer / suresh
Main method is called by jvm...
jvm is out side the class
so main method must be pulic
then only jvm can access.
No instance of the class is needed to
execute the static method.
