What is _init_?
__init__

The __init__ method is similar to constructors in C++ and Java. Constructors are used to initialize the object’s state. The task of constructors is to initialize(assign values) to the data members of the class when an object of class is created. Like methods, a constructor also contains collection of statements(i.e. instructions) that are executed at time of Object creation. It is run as soon as an object of a class is instantiated. The method is useful to do any initialization you want to do with your object.

What is method overloading. ?
In other words, we can say that Method overloading is a concept of Java in which we can create multiple methods of the same name in the same class, and all methods work in different ways. When more than one method of the same name is created in a Class, this type of method is called Overloaded Methods.
Comment down the difference between method overloading and method overriding...

Method declaration in java
Like a class, a method definition has two major parts: the method declaration and the method body. The method declaration defines all the method's attributes, such as access level, return type, name, and arguments, as shown in the following figure. The method body is where all the action takes place.

Inheritance allows us to define a class that inherits all the methods and properties from another class. Parent class is the class being inherited from, also called base class. Child class is the class that inherits from another class, also called derived class.

What is single inheritance?
Single inheritance can be defined as a derived class to inherit the basic methods (data members and variables) and behavior from a superclass. ... Basically, java only uses a single inheritance as a subclass cannot extend more superclass. Inheritance is the basic properties of object-oriented programming.

Multilevel inheritance in java?
When a class extends a class, which extends anther class then this is called multilevel inheritance. So in this case class C is implicitly inheriting the properties and methods of class A along with class B that's what is called multilevel inheritance. ...
