Prerequisites: Basic computer fundamentals, knowledge of C / C++ programming.

Sessional Marks: 60 · End Exam: 40 · Internal Tests: 2 (T1 after CO1 & CO2, T2 after CO3 & CO4)

Course Outcomes

CO-1

Develop classes for real time applications and establish the connectivity among the classes using inheritance and usage of strings.

CO-2

Modularize the application using packages, Interfaces and use of file concepts.

🔬 Lab Manual

Java Programming Practices Lab · 23CM9201 · Academic Year 2026–27 · CSE (AI & ML)

Lab Objectives: Understand OOP concepts and apply them in problem solving using Java; learn Java console programming.
Software Required: JDK 8+, Eclipse / NetBeans / IntelliJ IDEA / VS Code with Java Extension, Windows 10/11 or Ubuntu Linux.

List of Experiments

#	Week	Experiment Title & Description	CO
Exp 1	1 & 2	Bank Account Management System OOP: Classes, Encapsulation, Inheritance, Polymorphism, Dynamic Binding. Classes: Account, SavingsAccount, CurrentAccount.	CO1
Exp 2	3	Java Basics – Prime Palindrome Check Check whether a given number is a prime palindrome.	CO1
Exp 3	3	Java Basics – Command Line Arguments Read marks of five subjects via command line; print total and average.	CO1
Exp 4	4 & 5	Classes and Objects – Farm Animals Application Design a farm animals app: where they stay, what they eat, the sound they make.	CO1
Exp 5	4 & 5	Class Diagram – Customer, Order, SpecialOrder, NormalOrder Implement a class diagram with Customer, Order, SpecialOrder, and NormalOrder.	CO1
Exp 6	4 & 5	Constructor Overloading – Employee Data by Cadre Maintain employee data (name, id, designation, salary, promotion status) using constructor overloading.	CO1
Exp 7	6	String Handling – Longest Substring Without Repeating Characters "abcabcbb" → 3 ("abc"), "pwwkew" → 3 ("wke").	CO1
Exp 8	7	Method Overriding – Banking System (RBI, SBI, HDFC) Dynamic polymorphism: RBI 4%, SBI 7%, HDFC rate via overriding.	CO1
Exp 9	8	Interfaces – Employee Categories Monthly salary for Regular, Contract, and Vendor employees using interfaces.	CO2
Exp 10	9	Packages – Roman to Integer Conversion Define package `number` with `Roman` class; implement `romanToInteger()`. "LVIII" → 58.	CO2
Exp 11	10	File Handling – Pattern Frequency Count Count occurrences of 'pe' and 'pi' in sample.txt. Expected: 'pe'=20, 'pi'=12.	CO2
Exp 12	11	Exception Handling – Mobile Number Validator Validate 10-digit mobile; raise ArrayIndexOutOfBoundsException, LengthNotSufficientException, or NumberFormatException.	CO3
Exp 13	12	Multithreading – Seat Reservation System Reserve seats from 100 using synchronized threads; only one person thread accesses reserve at a time.	CO3
Exp 14	13	Collection Framework – Letter Combinations of Phone Number Given digits 2–9, return all letter combinations (T9 keypad). "23" → ["ad","ae","af","bd","be","bf","cd","ce","cf"].	CO4
Exp 15	14	Collection Classes – Valid Parentheses Check if a string of '()', '{}', '[]' is valid using Stack and TreeSet.	CO4

💡 Tips to Score Well

✅ Submit writeups before each lab session

✅ Run programs without errors — execution marks are easy

✅ Prepare viva answers for every experiment

✅ Keep your lab record neat and up-to-date

✅ Don't miss this subject's lab sessions — attendance here (not total) gives you 5 marks

📌 About Mid Exams

Both Mid-1 and Mid-2 are out of 15 marks each. Your final mid score is calculated as:

🏆 Better mid score — ¾ (75%) of those marks are counted
📉 Lower mid score — ⅓ (33%) of those marks are counted So always aim to do well in both mids — but even if one goes badly, a strong performance in the other limits the damage.
