You need to close connection in finally block. Following is the Java code to close connection in JDBC and MySQL −
import java.sql.Connection; import java.sql.DriverManager; import java.sql.PreparedStatement; import java.sql.SQLException; public class CloseConnectionDemoInFinallyBlock { public static void main(String[] args) { String JDBCURL = "jdbc:mysql://localhost:3306/web?useSSL=false"; Connection con = null; try { con = DriverManager.getConnection(JDBCURL, "root", "123456"); System.out.println("connection is open"); } catch (Exception e) { e.printStackTrace(); } finally { try { con.close(); } catch (SQLException sqlException) { sqlException.printStackTrace(); } } } }
This will produce the following output −
connection is open
Here is the screenshot of the output −
