Programming Fundamentals in Java

This repository contains my complete journey through Programming Fundamentals, covering core Java concepts through hands-on coding.

Concepts Covered

Conditional Statements

• if-else statements with multiple logic-building examples
• switch statements written in different styles for flexibility

Loops

• Mastery of for, while, and do-while loops
• Looping through primitive types, strings, and arrays

Methods

• Simple reusable methods
• Method Overloading
• pass by value explained through examples

1D Arrays

• Array creation, access, and manipulation
• Passing arrays to methods and returning them
• Looping through arrays with different data types

2D Arrays

• Nested loop mastery
• Row-wise and column-wise operations
• Matrix-based logic problems

Jagged Arrays

• Dynamic array structures
• Sum, product, and flattening operations
• Fully user-driven input and structured output

Error/Exception Handling

• Simple codes for error handling
• try , catch , throws and finally
• Make your code error free and functioning without crashing

File I/O Handling

• Writing in the .txt files.
• Reading from the .txt files.
• Avoiding Exceptions and handling errors.

Notes

• Some commits may have shifted due to restructuring — check filenames and descriptions accordingly.
• Each .java file in this repo represents a small, focused concept or challenge.
• All code is written with clarity and output in mind for better understanding.

Practice Habit

By building small programs every day, I'm sharpening logic, mastering Java syntax, and preparing for real-world problem solving.
