Random Number Generator and Sorter

Random Number Generator And Sorter Application

Requirement

The requirement is to generate random number based on the user input (count) and sort them in ascending order using a sorting algorithm. The GUI should be used to capture the user input and should display the below details.

• Generated Random Number
• Sorted Random Number
• No of position changed (swap count for sorting)
• Time taken to sort the random numbers

Also, the application should persist the data even after restart.

Solution Proposed

Below are the technology stack used to achieve the solution.

Java 8

For Lambda Expressions and Stream APIs

Spring boot

To configure Spring MVC, embedded Servlet Container (used Tomcat 8.5 for this application) and H2 Database

Spring-MVC

To create loosely coupled web application

Spring-Data-JPA

To use the in-build JpaRepository to persist and retrieve data through query methods

H2 Database

To persist the data even after restart, I have the in-memory database

Maven

To build and package the application to JAR

Steps to execute the Application

• Make sure Java 8 is installed on your PC
• Clone the source code from https://github.com/rajaasthana/RandomNumberGeneratorAndSorter
• Import as Maven Project in Eclipse or any supported IDE
• Locate Application.java under com.randomnumbersorter package and run it as Java Application
• Once the server is started, launch the application using http://localhost:8080/home/ in any browser
• You can now generate and sort random numbers
