1.   Concept Mapping Assignment   (5 Marks)

Course: Core Java (Units 1–4)
Assessment Type: Internal 1 — Concept Mapping.
Total Marks: 5

Task:

Create a concept map that includes 10–15 key concepts from the Core Java syllabus. Focus on concepts that are fundamental to understanding Object-Oriented Programming (OOP) in Java.

Guidelines:

1.     Identify Key Concepts:
Select significant concepts from the Core Java syllabus (Units 1, 2, 3, and 4). Ensure a balance of foundational and advanced topics.

2.     Organize Hierarchically:
Begin with a central, overarching concept (e.g., Core Java or Object-Oriented Programming) and branch out to more specific concepts.

3.     Draw Connections:
Use lines to connect related concepts logically.

4.     Label Relationships:
On each connecting line, include a short phrase that explains the relationship (e.g., is a type of, uses, extends, implements).

5.     Add Cross-Links:
Where relevant, create links between different branches to show complex interdependencies. Cross-links often reflect deeper understanding.

6.     Ensure Clarity and Neatness:

o    Make your concept map visually clear and easy to follow.

o    Use neat handwriting or digital .

o    Keep the language concise and accurate.

Submission Format:

·         You may submit a hand-drawn map  .

·         Clearly mention your name, roll number, and class
