Java is a high-demand programming language. With its platform independence and multiplatform support, many organizations have turned to Java to get work done more efficiently. If you’re just starting with Java as a programming language, our advice is to try your hand at some real-world projects. Learning Java has never been easier.
Simple mini project in java with source code for 12th Students
Software development careers are much easier to secure when you have hands-on experience. When you’re working on your projects, it will be invaluable for you to work with Java since it is the most popular platform that people use in this industry.
Java is simple enough to get into, but hard to master which means that when you’re working on a project of your own you can learn so much more than what would be possible through classroom training alone.
Here is a list of some java projects for Students:-

Java projects using the oops concept
Java Projects on Object-Oriented Programing Concepts – Java is an Object Oriented Programming (OOP) language and is used to develop applications in various fields like computer programming, mobile application development, network security management, instant messaging, java web development, and so on.
OOP is a methodology to decompose the program into smaller modules called objects to make the program easy to maintain and enhance. OOP supports features like data hiding, inheritance, and polymorphism. Object-Oriented Programming Concepts.
How to Java projects with database connectivity with source code
Before establishing a connection between the front end and the back end i.e. your Java program and a database backend, you need to establish how that connection creates in the first place. As it happens, there’s already a technology for this called JDBC or Java Database Connectivity.
It should be noted that JDBC does have its roots in object-oriented programming as you may have guessed from its class name (using Java here but it works with other OOP languages as well). So let’s take a closer look at what exactly JDBC is and why it came into existence.
What is JDBC?
JDBC stands for Java Database connectivity. JDBC is an acronym for Java Database Connectivity. It’s essentially an updation to ODBC (Open Database Connectivity). JDBC is a developing set of class specifications that provides a way for Java customers to interact using their particular programs with the essential relational databases like MySQL, Oracle, etc.
A JDBC API performs the function of linking between Java and the database i.e it helps establish a connection between Java programs as well as databases so that customers could send data from their code and store it in the database for future use.
Steps to java projects connect with database:-
- The signification of database.
- Pack the drivers using the forName() process.
- Record the drivers using DriverManager.
- Select a connection using the Connection class object.
- Complete a comment.
- Run the query.
- Complete the connections.
Let’s talk about these steps before we get into writing code. We’ll go over what each one entails, then we’ll be able to write the code that will enable connectivity between our program as well as our database.
Step 1: The Signification of the database:-
In other to start with, you are first required to load the drive or signup it before using the program. Enrollment is to accomplish once in your program.
Step 2: Loading the Derivers:-
You can signup a drive in one of two types mentioned below as follows:
- Class.forName():- In this step, we can discuss Class.forName, firstly we can load the drive class file into memory at the compile time. There is no requirement of using new or create objects.
- DriveManager.registerDriver():- It is a Java inbuilt class with a static member register. Here we call the constructor of the drive class at run time.
Step 3: Select a connection using the Connection class object.
Once you can load a driver, establish connections as shown below as follows:-
- User:- username from which your SQL command prompt can allow.
- Password:- From which the SQL command prompt can allow.
- con:- con is a reference to the connection of the interface.
- URL:- URL stand for uniform resource locator,
You must know what type of database you’ll be communicating to so (Oracle in this case), as well as the driver that’ll use for the connection. It goes without mentioning your IP Address needs to be specified beforehand, along with the port number as well as the application service provider, in that order.
Step 4: Complete a Comment
Once you can connect the database with the project. The JDBC statement, callablestatement, as well as PreparedStatement interface, define the methods that enable you to send SQL commands as well as receive data from your database.
Step 5: Run the query
It is a significant portion of database connectivity i.e. running the query. Here a query is an SQL query. We know we can have multiple types of queries are:
- The query for updating/inserting a table in a database.
- The query for recovering data.
The executeQuery() method of the Statement interface is used to execute queries for retrieving values from the database. This method returns the object of ResultSet that can be used to retrieve all the records of a table. The executeUpdate(SQL query) method of the Statement interface is used to execute queries for updating or inserting data into a database table.
Step 6: Complete the connections
Once we have sent the data to the specified destination and are done using it, for the time being, we may close the connection. To do so, we must implement either Statement or ResultSet. If a Connection object is used in more than one place at a time, then automatically it means that you are making use of its thread-safety features. Close() is required whenever iterating through your connection or anytime there is no longer an immediate requirement to work with it.
