1. Number Guessing Game
The fun and easy project “Guess the Number” is a short Java project that allows the user to guess the number generated by the computer & involves the following steps:
- The system generates a random number from a given range, say 1 to 100.
- The user is prompted to enter their given number in a displayed dialogue box.
- The computer then tells if the entered number matches the guesses number or it is higher/lower than the generated number.
- The game continues under the user guessing the number.
You can also incorporate further details as:
- Limiting the number of attempts.
- Adding more rounds.
- Displaying score.
- Giving points based on the number of attempts.
The user interface includes an input value option where the player must enter the predicted value, as well as a display of the remaining guessing time. If the guessed number is correct after fulfilling the restrictions, the player wins; otherwise, the player loses. The number can be in the range of 1 to 100 or 1 to 1000. In addition, if the figure you’ve predicted is too high or too low in comparison to the actual value, the app will notify you with the message “Too High” or “Too Low.” The true value is revealed after the limited effort is completed.
2. Currency Converter
Different countries have different currencies and these currencies have daily variations relative to one another. People must be updated with the latest currency exchange rate while money transfer. As a result, the currency converter is a small Java project that provides a web-based interface for exchanging/converting money between different currencies. It is built with Ajax, Java servlets, and other web capabilities. Such applications have been applied in the fields of business, stocks, and finance.

When everything has come online, chatting is also performed online be it your online friends or anyone. Hence, this advanced chatting application has advanced features like smooth communication with video and audio call facilities, and many more.
We don’t have just one system; we have several systems that are linked together. Instead of using basic request-based communication, client and server communication is used. Sockets will be used to communicate with this program. On the same network, the server and client can run on different computers. Multiple clients can connect to a server and communicate with one another. These days, every app has a feature called ‘Help’ that allows you to talk with a bot, from transportation applications like Ola and Uber to food apps like Zomato and Swiggy.
Sockets are something new that one has to learn here in adhering to the advancement of the project because they will be used for networking, and TCP/IP protocols so communication can be built.
16. Email System
A great medium to conversate in an official way is through e-mails. Email system implemented using Java is of great value to organizations. So, advanced programmers can focus on the implementation of this project
The project functions something like this – the ISP’s (Internet Service Provider) mail server handles the emails sent from an ISP. All the sent emails first come to the mail server, after which they are processed and forwarded to the collector’s destination where another mail server is located.
On the collector side, the mail server receives incoming emails and sorts them into the inbox electronically. The receiver can now examine the emails that have been sent to them using their email application. The entire transaction takes place through the program’s direct connection to the mail server, making it far safer than traditional email client software.
This Email System is designed for sending and receiving emails in a correct format for official communication. To access emails, this system uses HTTP port 80, and the two primary protocols that can be utilized are SMTP (Simple Mail Transfer Protocol) and POP3. Data can be transferred using the Java mail API. The ISP mail server receives and processes every incoming mail before forwarding it to the intended receiver.
17. Simple Search Engine
You search for anything using a search engine so building a simple search engine can be one of the best projects. Applying a ranking algorithm can give better results.
Simple Search Engine is a Java application created with the help of Servlets, SQL Server, and the Oracle database. It may include features such as a search bar that displays the top 30 websites that are linked to the keyword typed in. The SOIF (Summary Object Interchange Format) format is used to express the database holding resource descriptions. The Java interface offered by classes in the Java SDK is used to interact with the search server in order to access the database. Your search engine keeps track of the pages you’ve looked for, the pages you’ve visited in the last few days, the accounts you’ve linked to it, and so on.
18. Flappy Bird Game
