3. School Management System

 

school management system

 

This is a project heavily focused on the school management systems.

 

This project manages to keep a track of activities like count students, teachers, and funds.

 

But it does not cover up the topics like attendance, bus tracking, timetable, etc. In other words, this project does take care of the financial aspects of the school. Like proper track and management of funds. 

 

Working with this project you will encounter the concepts like :

  • Collection methods in Java.
  • OOP concepts etc.

4. Temperature Converter Tool 

 

Temperature Converter Tool

 

The temperature Converter tool is another simple JAVA project. It is similar to a currency converter and is built on the same platform. 

This project requires some basic concepts of JAVA and mathematical logic to solve this problem.

The interface can be built by using the useful classes of the JavaFX package.

 

Working of the project is as follows  :

  • The user needs to enter the value of the temperature he wants to be converted.
  • Then by these values entered the program will return the converted values to the user from Celsius to Fahrenheit or vice-versa. 
 
Source Code of the project :
import java.util.Scanner;
class FahrenheittoCelsius
{
	public static void main(String arg[])	
	{
	    double a,c;
             	    Scanner sc=new Scanner(System.in);	   	 
	    System.out.println("Enter  Fahrenheit temperature");
                   a=sc.nextDouble(); 
	    System.out.println("Celsius temperature is = "+celsius(a));		  	  	     
	} 
	static double celsius(double f)
	{	
	return  (f-32)*5/9;
	}
}

7.  Number Guessing Game :

 

number guessing game

 

This is a simple and basic game developed in JAVA. The game uses basic JAVA concepts for development.

This is a great projects for beginners entering the development area.

 

As this projects use many concepts in JAVA but in very simple way and uses limited JAVA libraries for execution.

 

Here some of the general rule that are to followed in the game:

  • The program is developed such that it will generate random number from 1 to 100.
  • A box is appeared in front of the user where he can enter the number they guess.
  • The computer checks the entered number is correct or high/low then informs the user.
  • The game continues till the correct number is guessed.

 

Source Code of the project :
import java.util.Scanner;
  
public class GFG {
    public static void
    guessingNumberGame()
    {
        Scanner sc = new Scanner(System.in);
  
        int number = 1 + (int)(100
                               * Math.random());
        int K = 5;
  
        int i, guess;
  
        System.out.println(
            "A number is chosen"
            + " between 1 to 100."
            + "Guess the number"
            + " within 5 trials.");
  
        for (i = 0; i < K; i++) {
  
            System.out.println(
                "Guess the number:");
            guess = sc.nextInt();
            if (number == guess) {
                System.out.println(
                    "Congratulations!"
                    + " You guessed the number.");
                break;
            }
            else if (number > guess
                     && i != K - 1) {
                System.out.println(
                    "The number is "
                    + "greater than " + guess);
            }
            else if (number < guess
                     && i != K - 1) {
                System.out.println(
                    "The number is"
                    + " less than " + guess);
            }
        }
  
        if (i == K) {
            System.out.println(
                "You have exhausted"
                + " K trials.");
  
            System.out.println(
                "The number was " + number);
        }
    }

10.  Online Cab Booking System

 

online cab booking

 

Online Cab Booking is one the most awesome and cool projects in this list.

Many huge companies are built around this space. Some examples of companies are Uber, Lyft, Gett and many more.

 

The applications provides the booking of the cabs from one place to the another. 

 

The application functions like the user logs in or signs up through the account and then the user shares the location of his/her to the driver. Then they book the cab by any payment gateway methods.

Then the driver receives the location and the route of the passenger. In this way the cab booking application works.

 

The project is a bit too heavy for beginners but they can definitely try the smaller versions and can experiment and add some new and exciting features to it.

 

Projects for Intermediate and Advanced Level JAVA programmers.

 

Here are some projects for intermediate and advanced-level programmers.

 

  • Intelligent Hospital System in Java
  • Sports Event Management System.
  • Online Book Reading Platform 
  •  Social Networking Site
  • Time Conversion by Country
  • College Voting System
  • Online Doctor Appointment

 

Conclusion :

So from the above, we come to understand that there are many implementations of the JAVA language.

Projects develop the logic to solve problems and make practical use of the theoretical knowledge we have.
