Monolithic vs Microservices Architecture

In software development, Monolithic and Microservices are two popular architectural styles used to build applications, and they differ in how the application is structured and managed.

Java connects to MySQL using JDBC (Java Database Connectivity), a standard API that allows Java applications to interact with relational databases.

JPA stands for Java Persistence API. It is a Java specification used for managing relational data in Java applications.

Java Full Stack Development involves building both the frontend (client-side) and backend (server-side) of web applications. To streamline development, testing, deployment, and collaboration, developers use a variety of tools and technologies

Java connects to MySQL using JDBC (Java Database Connectivity), which is a standard API for interacting with relational databases.

Steps to connect Java to MySQL:

1. Add MySQL JDBC Driver

   • Include the MySQL Connector/J library in your project (JAR file or Maven dependency).

2. Load the Driver (optional in newer versions)

Class.forName("com.mysql.cj.jdbc.Driver");

3. Establish a Connection

String url = "jdbc:mysql://localhost:3306/database_name";
String user = "root";
String password = "password";

Connection conn = DriverManager.getConnection(url, user, password);

4. Create a Statement and Execute Queries

Statement stmt = conn.createStatement();
ResultSet rs = stmt.executeQuery("SELECT * FROM students");

while(rs.next()){
    System.out.println(rs.getString("name") + " - " + rs.getInt("age"));
}

5. Close the Connection

rs.close();
stmt.close();
conn.close();

⚡ Summary:

• JDBC is the bridge between Java and MySQL.

• Use Connection, Statement/PreparedStatement, and ResultSet to interact with the database.

If you want, I can also show a full Java example with PreparedStatement to prevent SQL injection, which is best practice.
