Overloading.java

// Understanding Overloading
// Overloading is a concept in Java where a class can have multiple methods with the same name but different parameters.
// Method or Constructor overloading is a static/compile-time polymorphism.
// The methods must have the same name but different parameters.
// The return type of the methods can be different.

// The methods can be overloaded in the same class or in a subclass.
// The methods can have different access modifiers.
// The methods can throw different exceptions.
// The methods can have different return types.
// The methods can have different number of parameters.
