Overloading->
1) Same name, different parameter list or types of parameters.
2) Sub class method can overload a superclass method.
3) Method be different access specifier.
4) It doesn't need inheritance.
5) All method should be in same class.
6) data types can be different.
7) Return type can be different.
ex:
int add(int a, int b)
int add(float a , float b)
are overloaded methods
overriding->
1) Method should be public.
2) It needs inheritance and virtual keyword
3) It needs virtual keyword before it declaration.
4) Method must have same name with same parameter in
different class.
5) It requires non-static method.
6) Method should have same data type.

Answer / kundan kumar
OverLoading : All the method will share the same name but
it differes based on the parameter, type of parameter and
number of parameter
OVERRIDING:-
it just in inheritance and the overriding
method must hold the same name and the same signatures .
the change maybe just in behavior .
The Dog class in the following example is the subclass and
the Animal class is the superclass. The Cat class overrides
eat() method inherited from Animal class.
public class Animal {
public void eat() {
System.out.println("Eat for Animal");
}
}
public class Dog extends Animal {
public void eat() {
System.out.println("Eat for Dog");
}
}

Answer / syed
OVERLOADING: When we add a new method with the same namein
a same class/derived classbut with differentnumber/types of
parameters.
OVERRIDING: When we need to provide different
implementation in a child class than the one provided by
base class,we define the same method with same signatures
in child class.

Answer / sudesh sangwan
overriding:in overriding is done in inheritance,we having same method name as in base class and having same signature.
it is resolved at run time.
overloading:
in overloading we have many method with same name but different parameter.
it is resolved at compile time.
eg:
int add(int a,int b)
int add(float a,float b)
int add (string a,string b)
