Description

This repository contains multiple Core Java programs for practice and learning.
It includes programs on arrays, patterns, recursion, functions, operators, keywords, loops, control statements, strings, StringBuilder, sorting algorithms, bit manipulation, mathematical operations, odd/even checks, prime number checks, multiplication tables, and more.

Technologies

• Java SE
• Core Java concepts (OOP, loops, arrays, recursion, functions, operators, strings)
• Optional: Any IDE like VS Code
