A collection of Java programs I wrote while learning the fundamentals of Java programming. This repo covers everything from basic syntax to object-oriented programming concepts.

• Basics — variables, data types, operators, input/output
• Control Flow — if-else, switch, ternary operator
• Loops — for, while, do-while, nested loops
• Arrays — 1D arrays, 2D arrays, array operations
• Strings — string methods, manipulation, palindrome, reverse
• Methods — user-defined methods, recursion
• OOP Concepts — classes, objects, constructors, inheritance, polymorphism, encapsulation, abstraction
• Exception Handling — try-catch, finally
• Collections — ArrayList, HashMap (basics)

1. Clone the repo

git clone https://github.com/aasthanandekar/basic-java.git
cd basic-java

2. Compile any file

javac HelloWorld.java

3. Run it

java HelloWorld

• How Java is structured — classes, main method, and compilation
• Difference between primitive and reference data types
• Writing clean loops and conditions
• Core OOP concepts — inheritance, polymorphism, encapsulation
• How exceptions work and how to handle errors gracefully
• Thinking in an object-oriented way
