🎯 Exam Strategy

Guaranteed Marks Plan

How to approach each part of the Core Java exam for maximum marks.

Part A
25 MCQs × 1 = 25 marks
Target: 20–23 / 25
  • OOP concepts: Encapsulation, Polymorphism, Abstraction 8/8
  • "Predict the Output" — static, this, super keywords 8/8
  • String vs StringBuilder vs StringBuffer 7/8
  • Exception hierarchy: checked vs unchecked 7/8
  • Thread lifecycle: NEW → RUNNABLE → BLOCKED → DEAD 7/8
  • ArrayList vs LinkedList vs HashMap 7/8
  • Interface vs Abstract class 6/8
  • Constructor chaining with this() and super() 6/8
  • Java 8: Lambda expressions and Stream API basics 5/8
  • final, finally, finalize differences 6/8
Part B
5 Questions × 8 = 40 marks
Target: 32–40 / 40
QUnitExpected Topic
21U1/U2OOP Pillars or Inheritance with code
22U2Interface + Abstract Class comparison with program
23U3Multithreading — Runnable/Thread with sync 🔥
24U3/U4Exception Handling OR Collections (ArrayList/HashMap) 🔥
25U4/U5Generics OR File I/O OR Lambda Expressions
Part C
1 Question × 10 = 10 marks
Target: 8–10 / 10

Choose 1 of 2 questions. Typical options:

Q.26
Multithreading with Producer-Consumer / synchronization 🔥 OR Design a class hierarchy using Inheritance + Polymorphism
Q.27
Collections Framework — implement using ArrayList + HashMap with output OR Java 8 — Streams + Lambda expressions program
💡 Java Exam Secret: Always show the OUTPUT after your code. Examiners award marks for correct output traces even when code has minor errors. Write // Output: ... as comments.
