Core Concepts

A collection of introductory programs focusing on the fundamentals of the Java language.

• FunctionsPrintMyName.java: Demonstrates basic function creation and usage with String arguments.
• FunctionsPrintTheSum.java: A simple function to calculate and return the sum of two integers.
• averageof3.java: Calculates the average of three numbers.
• Homework1Calc.java: A basic calculator that performs arithmetic operations based on user input.
• UserinputCount.java: A program that counts positive, negative, and zero inputs from a user in a loop.
• numComparison.java / GreaterOfTwo.java: Examples of using conditional statements (if-else) to compare numbers.
• Infiniteloop.java: An example of creating and controlling loops.

Algorithms

Implementations of common and fundamental algorithms.

• FunctionsPrintTheFactorial.java: A function to calculate the factorial of a number using a loop.
• Exponential.java: A custom function to calculate exponents without using Math.pow().
• GCDCalculator.java: Implements the Euclidean algorithm to find the Greatest Common Divisor of two numbers.

How to Compile and Run

All programs in this repository can be compiled and run from the command line.
