Java Programs
Learn Java programming with hands-on examples. Practice core syntax, OOP concepts, collections, multithreading, and more.
Topics & Solutions
Module 1: Basic Java Programs
Fundamental Java programs to get started with syntax, I/O, operators, and basic problem solving.
Module 2: Conditional Programs
Java programs that use if-else, nested if, and switch-case to make decisions based on conditions.
Module 3: Loop Programs
Java programs that practice loops (for, while, do-while) and iterative logic.
Module 4: String Programs
Java string manipulation programs covering reversal, searching, counting, validation, and transformations.
How to Practice Java Programs
Start with one topic at a time and solve all programs in sequence. Write code yourself first, then compare with the provided solution to understand cleaner logic and better edge-case handling.
Focus on pattern recognition: many interview and exam questions are variations of arrays, strings, loops, recursion, and object-oriented fundamentals. Build notes for each pattern with one reusable template.
For revision, re-solve previously completed problems without looking at code. This improves recall speed and confidence during coding rounds and timed assessments.
