Q2. What is inheritance in java

Q2. What is oops,java
Ans. 
OOPs (Object-Oriented Programming) is a programming paradigm based on the concept of objects, which can contain data and code.
• OOPs focuses on creating reusable code by organizing data into objects and defining their behavior through methods.

• Java is a popular programming language that supports OOPs principles such as encapsulation, inheritance, polymorphism, and abstraction.

Q3. Explain the process of execption handling
Ans. 
Exception handling is the process of handling errors and unexpected events in a program.
• Exceptions are thrown when an error occurs in the program.

• The try-catch block is used to handle exceptions.

Q5. How multiple inheritance is made possible in java
Ans. 
Java does not support multiple inheritance, but it can be achieved through interfaces.
• Java does not allow multiple inheritance of classes due to the diamond problem.

• However, multiple inheritance can be achieved through interfaces.

• A class can implement multiple interfaces, which can have their own default implementations.

• Example: class A implements Interface1, Interface2 { }
