difference between method overloading and method overriding in java code example
Example 1: what is method overloading and method overriding in Java?
Method overloading is providing two separate methods in a class with the same name but different arguments, while the method return type may or may not be different, which allows us to reuse the same method name.
Method overriding means defining a method in a child class that is already defined in the parent class with the same method signature, same name, arguments, and return type
Example 2: what is method overloading in java
Method overloading is providing
two separate methods in a class
with the same name but different arguments,
while the method return type
may or may not be different, which
allows us to reuse the same method name.
In my framework==
I use implicit wait in Selenium. Implicit wait
is an example of overloading. In Implicit wait
we use different time stamps such as SECONDS, MINUTES, HOURS etc.,
A class having multiple methods with
same name but different parameters
is called Method Overloading
Example 3: overloading and overriding in java
Method overloading is providing two separate methods in a class with the same name but different arguments, while the method return type may or may not be different, which allows us to reuse the same method name.
Method overriding means defining a method in a child class that is already defined in the parent class with the same method signature, same name, arguments, and return type
Example 4: overriding vs overloading
Method Overloading
Method overloading is providing two separate
methods in a class with the same name but
different arguments, while the method return type
may or may not be different,
which allows us to reuse the same method name.
1) Method Overloading occurs with in the same class
2) Since it involves with only one class inheritance
is not involved.
3)In overloading return type need not be the same
4) Parameters must be different when we do
overloading
5) Static polymorphism can be acheived using
method overloading
6) In overloading one method can’t hide the another
Method Overriding
Overriding means same method name and same parameter,
occur in different class that has inheritance relationship.
we use method overriding to implement
specific functionality to the method.
1) Method Overriding occurs between
two classes superclass and subclass
2) Since method overriding occurs between superclass
and subclass inheritance is involved.
3) In overriding return type must be same.
4) Parameters must be same.
5) Dynamic polymorphism can be acheived using
method overriding.
6) In overriding subclass method hides that of the
superclass method
