How to read data from MySQL and process it using Java

In Java, we can use JDBC (Java Database Connectivity) to connect and operate the MySQL database. Below is a detailed guide explaining the steps on how to read data from a MySQL database and process it.

Step 1: Import the necessary libraries
First, you need to import the libraries related to database connection and operation in Java. In this example, we will use the MySQL Connector/J library to connect and operate the MySQL database. You can download and install the library on the official MySQL website.

import java.sql.*;

Step 2: Connect to the MySQL database
Before you start reading data, you need to connect to the MySQL database. You need to provide the database connection URL, username and password. Here is an example:

String url = "jdbc:mysql://localhost:3306/mydatabase";
