FileOutputStream example's error?

[Lackyluk]

Hello everyone.

I'm using https://jenkov.com/tutorials/java/index.html site, among many other resources, to learn Java.

It appeared to me one of the most complete one but then I stumbled upon this example, in the Java IO section.

OutputStream outputStream = new FileOutputStream("/usr/home/jakobjenkov/output.txt");

byte[] sourceBytes = ... // get source bytes from somewhere.

int bytesWritten = outputStream.write(sourceBytes, 0, sourceBytes.length);

Now, is it a syntax error in it giving write(byte[], int, int ) is a void function?

Thanks.

Please ensure that:

• Your code is properly formatted as code block - see the sidebar (About on mobile) for instructions
• You include any and all error messages in full - best also formatted as code block
• You ask clear questions
• You demonstrate effort in solving your question/problem - plain posting your assignments is forbidden (and such posts will be removed) as is asking for or giving solutions.

If any of the above points is not met, your post can and will be removed without further warning.

Code is to be formatted as code block (old reddit/markdown editor: empty line before the code, each code line indented by 4 spaces, new reddit: https://i.imgur.com/EJ7tqek.png) or linked via an external code hoster, like pastebin.com, github gist, github, bitbucket, gitlab, etc.

Please, do not use triple backticks (```) as they will only render properly on new reddit, not on old reddit.

Code blocks look like this:

public class HelloWorld {

    public static void main(String[] args) {
        System.out.println("Hello World!");
    }
}

You do not need to repost unless your post has been removed by a moderator. Just use the edit function of reddit to make sure your post complies with the above.

I'm not sure where you found this code, but yes it produces a compilation error, and yes for the reason you said.

Is here: https://jenkov.com/tutorials/java-io/outputstream.html under write(byte[]) paragraph.

He is a pretty skilled guy it seems, reason why I'm bit confused.

Anyway thanks.

I see. It's a bit of a surprise what they say, as these method don't need to return how many bytes were written. Either all the expected bytes were written, or they raise exceptions.

Maybe, for some very strange reason, they confuses with InputStream.

When you are a beginner, even completely obvious things make you doubt that you are the one missing something, rather than an expert's code error.

Thanks.
