How do I use JDBC in my Java application?

How do I use JDBC in my Java application?

To use JDBC, you need to include the JDBC driver in your project, establish a connection, and execute SQL queries.

What are the steps to connect to a MySQL database using JDBC?

First, load the MySQL driver, then use DriverManager to establish a connection with the database URL, username, and password.

Can you show me a code example for connecting to a database?

Sure! Here's a simple example:

import java.sql.*;

public class DatabaseConnection {
    public static void main(String[] args) {
        try {
            Class.forName("com.mysql.cj.jdbc.Driver");
            Connection conn = DriverManager.getConnection("jdbc:mysql://localhost:3306/mydb", "user", "password");
            System.out.println("Connected to the database!");
            conn.close();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

What are some common exceptions I should handle when using JDBC?

Common exceptions include SQLException, ClassNotFoundException, and NullPointerException. Always handle these to ensure your application runs smoothly.
