Does Java have a using statement?

Question

Does Java have a using statement that can be used when opening a session in hibernate?

In C# it is something like:

using (var session = new Session()         


        

Answer 1

Before Java 7, there was no such feature in Java (for Java 7 and up see Asaph's answer regarding ARM).

You needed to do it manually and it was a pain:

AwesomeClass hooray = null;
try {
  hooray = new AwesomeClass();
  // Great code
} finally {
  if (hooray!=null) {
    hooray.close();
  }
}

And that's just the code when neither // Great code nor hooray.close() can throw any exceptions.

If you really only want to limit the scope of a variable, then a simple code block does the job:

{
  AwesomeClass hooray = new AwesomeClass();
  // Great code
}

But that's probably not what you meant.
