Practical assignments can involve student records, inventory data, employee information, and customer management systems.

Exception Handling in Core Java

Errors can occur during file operations, user input processing, database access, and other application activities. Consequently, developers need exception handling techniques to manage failures appropriately.

Exception Handling in Java teaches students how to identify exceptional conditions and respond without hiding important errors.

Topics Covered

• Exception hierarchy
• Checked exceptions
• Unchecked exceptions
• Try and catch blocks
• Finally block
• Throw and throws

Core Java Interview Questions for Freshers

Students preparing for Java developer interviews should revise both programming concepts and practical coding problems.

1. What is Java?

Java is a general-purpose programming language used to develop many types of applications. Its platform model allows compiled Java bytecode to run on compatible Java Virtual Machines.

2. What is the difference between JDK and JVM?

The JDK provides tools for developing Java applications, including the compiler. Meanwhile, the JVM executes Java bytecode.

3. What are the main OOP concepts in Java?

The main object-oriented concepts are encapsulation, inheritance, polymorphism, and abstraction. Together, they support structured and reusable application design.

4. What is the difference between method overloading and overriding?

Method overloading uses the same method name with different parameter lists. In contrast, overriding allows a subclass to provide a different implementation of an inherited method.

5. Why is String immutable in Java?

A String object’s value cannot be changed after creation. Consequently, operations that appear to modify a String produce a different String value.

6. What is the difference between ArrayList and HashSet?

ArrayList maintains an ordered list and permits duplicate elements. HashSet stores unique elements and does not guarantee iteration order.

7. What is exception handling?

Exception handling provides mechanisms for managing exceptional conditions during program execution. Therefore, developers can respond to failures appropriately.

8. What is multithreading?

Multithreading allows multiple threads to execute within an application. However, shared data may require synchronisation to avoid concurrency problems.

9. What is the Stream API?

The Stream API supports operations on sequences of elements, including filtering, mapping, and aggregation. Additionally, it can make certain data-processing operations more expressive.

10. What is JDBC?

JDBC is a Java API used to communicate with relational databases. It supports executing SQL statements, retrieving results, and managing transactions.
