如何使用java连接到mysql？

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

public class MySQLConnectionExample {
    public static void main(String[] args) {
        // MySQL数据库连接信息
        String url = "jdbc:mysql://localhost:3306/mydatabase";
        String username = "your-username";
        String password = "your-password";

        // 建立数据库连接
        try (Connection connection = DriverManager.getConnection(url, username, password)) {
            // 创建Statement对象
            Statement statement = connection.createStatement();

            // 执行SQL查询
            String sql = "SELECT * FROM mytable";
            ResultSet resultSet = statement.executeQuery(sql);

            // 处理查询结果
            while (resultSet.next()) {
                String column1 = resultSet.getString("column1");
                int column2 = resultSet.getInt("column2");
                // 处理查询结果...
            }

            // 关闭结果集和Statement对象
            resultSet.close();
            statement.close();
        } catch (SQLException e) {
            e.printStackTrace();
        }
    }
}
