Java Small Projects Collection

Overview

This repository contains a collection of small Java projects designed for learning and practicing various Java concepts. Each project focuses on specific programming techniques, problem-solving skills, and real-world application scenarios.

Projects Overview

1. Calculator

A simple arithmetic calculator that supports basic operations such as:

-> Addition
-> Subtraction
-> Multiplication
-> Division

Concepts Practiced:

Through this project, I have learnt:

• Conditional statements (if, switch)
• User input handling
• Basic OOP (Encapsulation, Class Design)

2. Mark Evaluation (Grades)

A program to evaluate student grades based on their marks. Features include:

-> Determining the grade for a given mark
-> Classifying marks into specific ranges (A, B, C, D, E)

Concepts Practiced:

Through this project, I have learnt:

• Conditional statements (if, switch)
• User input error handling

3. Array Operations

A program that performs the following operations on an array of numbers:

-> Find the minimum and maximum values
-> Calculate the average of all elements
-> Sort the array

Concepts Practiced:

Through this project, I have learnt:

• Array manipulation
• Looping constructs (for, while)
• Sorting algorithms

4. String Operations

A program for basic string manipulations:

-> Reverse a string
-> Check if a string is a palindrome
-> Identify vowels and consonants in a string
-> Convert a string to uppercase

Concepts Practiced:

Through this project, I have learnt:

• String handling (charAt, toUpperCase)
• Iteration through strings
• Logical problem-solving

5. Employment Management

A mini-project to manage employee records:

-> Add, remove, and view employee details
-> Store employee details using ArrayList
-> Search for employees based on criteria (e.g., ID or name)

Concepts Practiced:

Through this project, I have learnt:

• Use of ArrayList for dynamic data storage
• Object-oriented principles (Encapsulation, Class Design)
• Comparator for sorting

Getting Started

Prerequisites

• Java Development Kit (JDK) installed
• An IDE or text editor (e.g., IntelliJ IDEA, Eclipse, or VS Code)

Running the Programs

Clone this repository:

git clone https://github.com/KABILANSRK/LearnJava.git

Navigate to the project folder:

cd Java-Projects

Compile and run the .java files:

javac ProgramName.java
java ProgramName

What I have Learnt

By exploring these projects, I have gained hands-on experience with:

• Java basics and intermediate programming techniques
• Working with arrays, strings, and collections (ArrayList)
• Error handling and debugging
• Real-world problem-solving using Java
