How does JDBC connect to Java program?

The steps for connecting to a database with JDBC are as follows:

1. Install or locate the database you want to access.
2. Include the JDBC library.
3. Ensure the JDBC driver you need is on your classpath.
4. Use the JDBC library to obtain a connection to the database.
5. Use the connection to issue SQL commands.

How do you call a connection class in Java?

Steps For Connectivity Between Java Program and Database

1. Import the database.
2. Load the drivers using the forName() method.
3. Register the drivers using DriverManager.
4. Establish a connection using the Connection class object.
5. Create a statement.
6. Execute the query.
7. CLose the connections.

How is JDBC connection established?

Step1: Register the driver: To develop a basic JDBC application, first of all, you need to register the driver with the DriverManager. You can register a driver in two ways, one is using registerDriver() method of the DriverManager class and, using forName() method of the class named Class. Driver myDriver = new com.

What is the key difference between JDBC and ODBC?

The most basic difference between JDBC and ODBC is that JDBC is language and platform dependent. On the other hand, the ODBC is language and platform independent. Java Database Connectivity is an acronym for JDBC, and on the other hand, Open Database Connectivity is an acronym for ODBC. The code for ODBC is complex and is hard to learn.
