如何使用Java与MySQL交互？

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.Statement;

public class JavaMySQLExample {
    public static void main(String[] args) {
        String url = "jdbc:mysql://localhost:3306/your_database_name";
        String user = "your_username";
        String password = "your_password";

        try {
            // Load the JDBC driver
            Class.forName("com.mysql.jdbc.Driver");

            // Establish a connection to the database
            Connection connection = DriverManager.getConnection(url, user, password);

            // Execute a query
            Statement statement = connection.createStatement();
            ResultSet resultSet = statement.executeQuery("SELECT * FROM your_table_name");

            // Process the result set
            while (resultSet.next()) {
                int id = resultSet.getInt("id");
                String name = resultSet.getString("name");
                System.out.println("ID: " + id + ", Name: " + name);
            }

            // Close the connection
            connection.close();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}
