Enhance the Student Grade Tracker application by integrating a database to store and retrieve student data. You will create the necessary database, define the table structure, and establish a connection to it in Java using JDBC.

Activity 2 - Connecting to a Database

Step 1: Import Required Libraries

• Import the required JDBC library for your chosen database system. For example, if you're using MySQL, import the "mysql-connector-java" library.

Step 2: Create a Java Class

• Create a new Java class called "DatabaseConnection".

Step 3: Write the Code

• Inside the "DatabaseConnection" class, copy and paste the provided Java code for creating and connecting to the database.

Step 4: Modify Database Connection Details

• Modify the "DB_URL", "DB_USERNAME", and "DB_PASSWORD" variables in the code to match your database connection details.

Step 5: Run the Program

• Run the Java program.
• Check the console output for the success message "Database created and connection established successfully."

Step 6: Verify the Database

• Use your database management system to verify that the "students" table has been created in the database.
