Document variable

[captain alge]

Just a quick and probably silly question, how do I set a document variable? I imagine it's is something like :

Document myDoc = new Document("C:/folder/file");

but that doesn't seem to work...
(I get an error saying javax.swing.text.Document is abstract, can not be instantiated)

cheers!

Would File work?

Plus, remember that "/" is the escape character. For a literal forward slash, use "//".

Document is abstract as the error suggests. Go to the document API and find a concrete implementation( I think DefaultStyledDocument) is one type.

[captain alge]

No, apparently I need a document

[sunde887]

Good luck instantiating an interface. If we are thinking of the same thing, a document is an interface. You can't create an instance of it, instead you create an instance of a class that implements the document interface. Google java 6 document.

Nope, it's the backslash that's the escape character; also Document is an interface, you can't instantiate it. You have to find a non-abstract class that implements the interface (the API documentation will help you) and instantiate that.

how do I set a document variable?

Without adequate background information, nobody is going to be able to answer that. What exactly are you aiming to do? (note, 'what', not 'how')

forget it, I found an alternative way of doing what I wanted

[sunde887]

Alright, what were you trying to do exacty? If you are done please mark your thread solved with the thread tools at the top.

Good show! I'm sure many here will remember that and quickly forget about any future questions you might have.

I was trying to set the content of a text area to be the contents of a file

used:

FileReader input = new FileReader(new File(locationoffile));
myTextArea.read(input, evt);

instead

@Darryl.Burke not sure what your problem is

[sunde887]

You seemed like you came here, ignored advice and then just said nevermind.

You weren't actually looking for a document.

[captain alge]

The advice wasn't particularly helpful, you think I hadn't already checked the API?

I didn't realise I didn't require a document, otherwise I wouldn't have posted

[sunde887]

Your original question was overly vague and that's why we weren't able to provide you with a solid answer.

[captain alge]

yes I realize that now, and I apologize for that.
But at the time I thought it was a perfectly reasonable statement, I just assumed a Document was a form of File, but obviously I was wrong...

When you post in the forums in the future please try to be as clear as possible, people jere are very literal.
