How can you store data from an array into a database in Java?

To store data from an array into a database in Java, we typically need to implement it through JDBC (Java Database Connectivity). Below is a simple example code to achieve this functionality:

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.sql.SQLException;

public class ArrayToDatabase {
    public static void main(String[] args) {
        String url = "jdbc:mysql://localhost:3306/mydatabase";
        String username = "root";
        String password = "password";

        Connection connection = null;
        PreparedStatement preparedStatement = null;

        try {
            connection = DriverManager.getConnection(url, username, password);
            String sql = "INSERT INTO mytable (column_name) VALUES (?)";
            preparedStatement = connection.prepareStatement(sql);

            int[] array = {1, 2, 3, 4, 5};
            for (int i = 0; i < array.length; i++) {
                preparedStatement.setInt(1, array[i]);
                preparedStatement.executeUpdate();
            }

            System.out.println("Data inserted successfully");

        } catch (SQLException e) {
            e.printStackTrace();
        } finally {
            try {
                if (preparedStatement != null) {
                    preparedStatement.close();
                }
                if (connection != null) {
                    connection.close();
                }
            } catch (SQLException e) {
                e.printStackTrace();
            }
        }
    }
}

In the code above, the first step is to establish a connection with the database, followed by preparing an INSERT statement for data insertion. Then, an integer array is defined, where each element is iterated through in a loop and inserted into the database. Finally, the connection and prepared statement are closed. This is just a simple example, adjustments may be needed based on specific requirements in real scenarios.
