Difference between overloading and overridding?
Answers were Sorted based on User's Feedback
Overloading is the concept where there are many methods
with the same name in a class but the arguments passed
differ.Consider the example of method called
addition.Addition can be between integers,floating point
numbers etc., so same name addition is used for the various
methods of class but the parameters passed differ, it may
be integer or floating point.When the jvm checks for the
methods, the method is choosen depending upon the argument
passed.
Overriding is the concept where the method name is
same,arguments passed are also same and the return type is
also same.but the method implemented depends upon where its
defined and called

Answer / ravikiran
compile time polymorhism is named as overloading,and takes
place in the same class.Should have same method name but
must have different argument list.
Runtime polymorphism is named as overriding,and takes place
in diferent classes.Must have the same signature and
argument list including the order defined in the super
class.
