What would happen if we do not use encapsulation in java program? Ans: If we don’t use encapsulation in a program, fields will not be private and could be accessed by anyone from outside the class. For more encapsulation interview questions, go to this tutorial: Ja...

that contain data and methods. The primary purpose of object-oriented programming is to increase the flexibility and maintainability of programs. Object oriented programming brings together data and its behaviour(methods) in a single location(object) makes it easier to understand how a program works....

In the above program, it is not clear whether class A’s variable has been called or class B’s variable a has been called. In that case, JVM will throw an error. To solve this problem, concept of Interface was introduced. In Java, multiple interface is allowed but multiple inheritance...
- Functions that operate on data of an object bind together in data structures. - Objects communicate with each other by sending and receiving information through functions. - Easy addition of new data and functions whenever mandatory. - It follows a bottom-up design approach in program design....
2. Why is the static keyword important in Java OOP? The static keyword signifies that a field or method belongs to the class rather than any individual object. This allows shared access to the field or method across all instances of the class. ...
