Answer» In Method Overloading, the names of the methods in the same class are same but the arguments (TYPE and/or number) are DIFFERENT.
In Method Overriding, the names and arguments of the methods are same but one of the methods is in the super class while the other is in the sub class. Basis

Arguments
| The methods in overloading have different arguments.
| The methods in overriding have similar arguments.
| Polymorphism
| Overloading is a part of compile time polymorphism
| Overriding is a part of run time polymorphism.
| Occurrence
| Happens at compile time.
The binding of the OVERLOADED function CALLS it definition during compile time.
| Happens at runtime. The binding of the overridden function calls its definition during runtime.
| Static Methods
| Static Methods can be overloaded.
| Static methods cannot be overridden.
| Class
| Overloading is done in the same class
| Overriding is done in the parent and child class.
| Type of binding
| Static binding is USED for overloaded methods
| Dynamic binding is used for overridden methods
| Performance
| Method Overloading gives better performance as the binding is done during compile time.
| Method Overriding gives less performance as the binding is done during runtime.
| private methods
| private methods can be overloaded.
| private methods cannot be overridden.
| final methods
| final methods can be overloaded
| final methods cannot be overridden.
| Application
| Method overloading is used to increase readability of the program
| Method overriding is used to provide specific
implementation of the method
| Return type
| Return type of the methods does not matter during method overloading.
| In method overriding, the method should have a specific return type.
