}
}

The interface is a reference type in Java, similar to the class but its collection of abstract methods. A class can implement multiple interfaces.
24.Difference between class and interface?
Answer:
Below are the difference between Interface and class:-
The interface cannot be instantiated.
An interface doesn’t have any constructors.
Interface only have abstract methods.
A class implements an interface and extends a class.
An interface can extend multiple interfaces.
25. What is an abstract class?
Answer:
A class which contains the abstract keyword in a declaration is called abstract class. The properties of the abstract class are as follows:-
Abstract classes may or may not contain abstract methods but, if a class has at least one abstract method, then it must be declared abstract.
The abstract class cannot be instantiated.
To use an abstract class, we have to inherit it from another class.
If we inherit an abstract class, then we have to provide implementations to all the abstract methods in it.IBPS SO IT Officer Questions with answers
