Explanation:

• We know that "Inheritance in Java" is a concept that obtains or acquires the properties from one class to another. The bond shared by a father and a son can be an apt instance in this regard.
• A class can easily inherit attributes as well as methods from another class in Java.
• The subclass is the class that will inherit the properties. It is also called the child class.
• On the other hand, the superclass is the class from which the methods and properties are inherited. It is also called the parent class.
• The methods and properties of the base class are obtained by the derived classes in inheritance.
