Unit 1: Basic Java Programming and Syntax

Covers core syntax, variables, data types, operators, and control structures (if-else, loops). Solutions include:

• Question 1: Write a Java program to calculate the factorial of a number using recursion. Solution: Includes recursive method definition, input validation, and output formatting.
• Question 2: Demonstrate the use of arrays and loops to find the sum of even and odd numbers in an array. Solution: Uses for loops with conditional checks and array traversal.

Unit 2: Object-Oriented Programming (OOP) in Java

Focuses on classes, objects, inheritance, polymorphism, and encapsulation. Key solved questions:

• Question 3: Create a Java program to model a BankAccount class with methods for deposit, withdrawal, and balance check. Solution: Implements private fields, public methods, and exception handling for invalid transactions.
• Question 4: Demonstrate method overriding using a Vehicle hierarchy (e.g., Car, Bike). Solution: Includes superclass and subclass definitions with overridden displayDetails methods.

Unit 3: Exception Handling and File I/O

Explores exception handling mechanisms and file operations in Java. Sample solutions:

• Question 5: Write a program to read a text file and count the frequency of each word. Solution: Uses FileReader, BufferedReader, and a HashMap for word tracking.
• Question 6: Handle arithmetic exceptions and input mismatches in a calculator program. Solution: Implements try-catch blocks for division by zero and invalid inputs.

Unit 4: Collections Framework and Multithreading

Introduces Java Collections (List, Set, Map) and basic multithreading concepts. Key solved questions:

• Question 7: Implement a StudentManagementSystem using ArrayList and HashSet to store and retrieve student records. Solution: Includes CRUD operations with error handling.
• Question 8: Create a multithreaded program to print numbers from 1 to 10 using two threads (one for even, one for odd). Solution: Uses Thread class and synchronized blocks.

Unit 5: GUI Programming with Java Swing

Focuses on creating simple graphical user interfaces using Java Swing. Example solutions:

• Question 9: Design a login form with username/password fields and a submit button. Solution: Includes JFrame, JTextField, and event handling for validation.
