    You are essentially asking how to write an IDE (Integrated Development Environment). This is a big question. You might start by looking at existing IDE's (JBuilder, Forte...) and see how they do it. If you want source, there is probably an open source IDE you can lift most of your code from.

    While duffymo is correct in regard to most major database products, it's my understanding (warning! wild-ass guess coming) that the Hypersonic DB is more "application-centric" and the dynamic creation of databases is part of its design. It's pure Java database software, and therefore is not appropriate for all database projects, in particular those that require extremely high-performance.
    See http://hsqldb.org/
    I've not used it yet (but soon though), and I can't really advise anyone about it.
    However, I'm wondering if you phrased you question in a way that is confusing us. To most of us in casual conversation, a "database" is both (1) a large organized collection of data and (2) the software that is used to organize and access it. However, the phrase "create a database" usually means creating a (1) database (a collection of data) using an already created (2) database software, such as Oracle, MySQL, DB2, HSQDB, etc., etc. If you'r question is, how do a create some new database software using Java, the answer is that this is a very very big and hard thing to do for the general case and probably not something you want to be doing.

    File reldir=new File("NewDir");//relatively where your program runs
    reldir.mkdir();
    File absdir=new File("C:/NewDir");//absolute path

  • How to Create Symbolic link using pure Java code?

    Hi,
    I would appreciate if someone can tell me how to create symbolic link using JAVA API. I have looked into many forums but couldn't get a better answer.

    Java is likely not the tool to use here, as symlinks are not present in Windows while "pure" Java attempts to be platform independent. You could use Runtime.exec to execute the ln -s command
