public class Connect
{
public static void main (String[] args)
{
Connection conn = null;
try
{
String url = "jdbc:mysql://localhost:3306/mydb";
Class.forName ("com.mysql.jdbc.Driver");
conn = DriverManager.getConnection (url,"root"," ");
System.out.println ("Database connection established");
}
catch (Exception e)
{
e.printStackTrace();
}
finally
{
if (conn != null)
{
try
{
conn.close ();
System.out.println ("Database connection terminated");
}
catch (Exception e) { /* ignore close errors */ }
}
}
}
}
