JDBCis an acronym for Java Database Connectivity. It’s an advancement for ODBC ( Open Database Connectivity ). JDBC is a standard API specification developed in order to move data from the front end to the back end. This API consists of classes and interfaces written in Java. It basically acts as an interface (not the one we use in Java) or channel...
Below are the steps that explains how to connect to Database in Java: Step 1– Import the Packages Step 2– Load the drivers using the forName() method Step 3– Register the drivers using DriverManager Step 4– Establish a connectionusing the Connection class object Step 5– Create a statement Step 6– Execute the query Step 7– Close the connections
Let us discuss these steps in brief before implementing by writing suitable code to illustrate connectivity steps for JDBC.
