Database Connection in Java with Source Code

Database Connection in Java; When developing a project, it is really helpful to have a database storage need for the data. Because it gives you the ability to choose, update, delete, and add new data to your database. In order to successfully complete this tutorial, sqlitejdbc-v056 or another version was utilized. In order to successfully finish this lesson, please be sure to follow all of the steps below.

Connecting to database in java : Code Logic

Install the database that you wish to access, or find it first.
Include the JDBC library in your document.
Check to see that the JDBC driver you require is included in your classpath.
To establish a connection to the database, the JDBC library should be utilized.
The SQL commands can be issued by using the connection.

import java.sql.*;  
public class CONNECTING_JAVA_TO_DATABASE {

    /**
     * @param args the command line arguments
     */
    public static void main(String[] args) {
        try {
            Class.forName("com.mysql.jdbc.Driver");
            Connection con = DriverManager.getConnection(
                    "jdbc:mysql://localhost:3306/javaConnection", "root", "root");
 
            Statement stmt = con.createStatement();
            ResultSet rs = stmt.executeQuery("select * from sample");
            while (rs.next()) {
                System.out.println(rs.getInt(1) + "  " + rs.getString(2) + "  " + rs.getString(3));
            }
            con.close();
        } catch (Exception e) {
            System.out.println(e);
        }
    }

Importance of connecting java to mysql database?

Importance of connecting java to MySQL database

MySQL supports connectivity for Java client applications through MySQL Connector/J, a driver that implements the Java Database Connectivity (JDBC) API. The API is the industry standard for database-independent communication between the Java programming language and a wide range of – SQL databases, spreadsheets etc.

Advantage of connecting java with database?

When opening and terminating database connections for each user, JDBC connection pooling saves time by reusing previously opened connections. Simple access to the database: JDBC low-level database access facilitates the efficient execution of sophisticated SQL queries.

About the Project

Java Database Connectivity, more commonly known as JDBC, is an application programming interface (API) that enables programmers to connect to and interact with databases. It offers techniques for querying and modifying data stored in the database by utilizing update statements such as CREATE, UPDATE, DELETE, and INSERT from SQL, as well as query statements such as SELECT.

This project is build using java alone The following java project covers all of the required and vital elements that can be used for college projects by first-year, second-year, and final-year IT students.
