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())
{


}

So the object goes out of scope and closes automatically.

Answer 1

Sorry. No. Java does not have an equivalent to the using statement.

Not exactly the same but somewhat related, Java 7 (coming soon) will include Automatic Resource Block Management.

Answer 2

No, Java has no using statement equivalent.

Answer 3

Technically:

DisposableObject d = null;
try {
    d = new DisposableObject(); 
}
finally {
    if (d != null) {
        d.Dispose();
    }
}

Answer 4

As of now, no.

However there is a proposal of ARM for Java 7.

Answer 5

Any code inside a code block in Java will go out of scope outside of the code block - so for example you could use

{
    Session session = new Session();

    // session is in scope here.
}
// session is now out of scope and will be cleaned up by the GC at some point.
