What is Overloading, Overriding, Hiding, Shadowing and Obscuring in Java and Object-Oriented Programming?

Hello guys, today, I am going to explain a couple of fundamental object-oriented programming concepts in Java, like Overloading, Overriding, Hiding, Shadowing, and Obscuring. The first two are used in the context of a method in Java while the last three are used in the context of variables in Java. Two methods with the same name and same class but the different signature is known as overloading and the method is known as an overloaded method while a method with the same name and same signature but in parent and child class is known as overriding. On the other hand,  Hiding is related to overriding since the static and private method cannot be overridden, if you declare such methods with the same name and signature in parent and child class then the method in the child class will hide the method in the parent class.
