Hi,

Here is the answer,

First, you need to establish a connection with the data source you want to use. A data source can be a DBMS, a legacy file system, or some other source of data with a corresponding JDBC driver. Typically, a JDBC application connects to a target data source using one of two classes:

DriverManager:

DataSource:

Thanks.

While making a JDBC connection we go through the following steps: Step 1 : Register the database driver by using : Class.forName (\" driver class for that specific database\â??); Step 2 : Now create a database connection using : Connection con = DriverManager.getConnection (URL, username, password); Step 3: Now create a query using: Statement stmt = Connection. Statement (\"select * from TABLE NAME\"); Step 4: Execute the query: stmt.exceuteUpdate ();
