    Default implement interface

    I am creating an application in core java where i am using database. I need to create a database configuration file & include it all other files. So, how can i do that ?

    Java Code:
    Connection con = DriverManager.getConnection("jdbc:odbc:MYDSN","system","tiger");
    I cannot do this in an interface since only abstract methods exist there. I tried to create an another class file to extend it but my program is already extending other class i.e. javax.swing.JFrame

    How can i implement this ? just by creating the object of that class in main method ?

    Default Re: implement interface

    I'm not sure if I completely understand your question, but assuming you're trying to use the above 2 lines of code in an interface, then you're right that you cannot put them into the interface. They are to be placed into a concrete class. The concrete class does not need to extend anything to be able to use the above code. They only need to go into a method. See MySQL and Java JDBC - Tutorial. (Note the import statements to import the relevant classes.)
