Java Console Applications

This repository contains two Java console applications: a Modern Periodic Table and a Random Number Generator. Both applications demonstrate different aspects of Java programming and provide interactive user experiences through the command line interface.

1. Modern Periodic Table (PeriodicTable.java)

Overview

The Modern Periodic Table application is a comprehensive program that provides detailed information about chemical elements. It uses object-oriented programming principles to organize and display element data.

Structure

Element Class

class Element {
    String name;
    String symbol;
    int atomicNumber;
    String electronicConfiguration;
    String discoveredBy;
    String charge;
}

• The Element class serves as a blueprint for chemical elements
• Each element instance stores six key properties: name, symbol, atomic number, electronic configuration, discoverer, and charge
• Contains a displayDetails() method to print element information in a formatted manner

Main Class (PeriodicTable)

• Contains a database of all 118 elements in the periodic table
• Elements are stored in an array where the index position corresponds to (atomic number - 1)
• Implements an interactive menu system for user interaction

Features

1. Element Database: Contains complete information for all 118 elements
2. Search Functionality: Allows users to search for elements by atomic number
3. Detailed Information Display: Shows comprehensive details about each element
4. User-Friendly Interface: Simple menu system with clear options
5. Input Validation: Ensures atomic numbers are within valid range (1-118)

Program Flow

1. Displays welcome message and menu options
2. User can choose to:
   • Search for an element (Option 1)
   • Exit the application (Option 2)
3. When searching:
   • Enter atomic number
   • View detailed element information
4. When exiting:
   • Confirm exit choice
   • Receive appropriate closing message

2. Random Number Generator (RandomNumberGenerator.java)

Overview

A versatile random number generator that allows users to generate multiple random numbers within a specified range. The application demonstrates the use of Java's Random class and implements a loop-based menu system.

Structure

The application is contained in a single class that handles:

• User input processing
• Random number generation
• Result display
• Program flow control

Features

1. Customizable Range: Users can specify minimum and maximum values
2. Multiple Number Generation: Generate any quantity of random numbers in one go
3. Input Validation: Ensures valid ranges and counts
4. Continuous Operation: Users can generate multiple sets without restarting
5. User-Friendly Interface: Clear prompts and formatted output

Program Flow

1. Welcome message displayed
2. Main program loop begins:
   • User inputs minimum value
   • User inputs maximum value
   • Range validation occurs
   • User specifies quantity of numbers
   • Numbers are generated and displayed
3. After generation:
   • Option to generate more numbers
   • Option to exit program
4. Program continues until user chooses to exit

Error Handling

The application includes validation for:

• Invalid ranges (minimum ≥ maximum)
• Invalid counts (less than or equal to 0)

Technical Requirements

Dependencies

• Java Development Kit (JDK) 8 or higher
• Command line interface or terminal

How to Run

1. Compile the Java files:

javac PeriodicTable.java
javac RandomNumberGenerator.java

2. Run the desired program:

java PeriodicTable
# or
java RandomNumberGenerator

Implementation Notes

Modern Periodic Table

• Uses an array-based data structure for element storage
• Implements object-oriented principles through the Element class
• Memory efficient as elements are only created once during initialization

Random Number Generator

• Utilizes Java's Random class for number generation
• Implements a while loop for continuous operation
• Uses Scanner class for user input handling

Future Enhancements

1. Modern Periodic Table:

   • Add search by element name/symbol
   • Include more element properties
   • Add periodic table visualization

2. Random Number Generator:

   • Add option for different number distributions
   • Include duplicate number checking
   • Add file output capability
