FileInputStream question.

[Norm]

Why are you reading the file? Do you want to see its contents?
Where should read() put the data it reads?

[fatabass]

Norm,

There is nothing specific I want to do except learning JAVA.
Why are you answering my questions with questions?

As I was going through the API,

I have seen this method,
and my question is:

Why would I create an array and put it into read method as an argument which belongs to a FileInputStreamer object that is referencing to a file ?

and Fuburable's answer, altough not very clear to my as I am a beginner, has at least shown me a way.

Thank you for sparing your time, and trying to help.

If you want an InputStream that reads from a byte array (not a file), have a look at the ByteArrayInputStream class. (it is also mentioned in the API documentation as a sub class of the InputStream class).

kind regards,

Jos

My questions are to make you think. What is your answer to the last question?

[fatabass]

Why are you reading the file? Do you want to see its contents?
Where should read() put the data it reads?

I am not reading anyfile.. I do not want to see its contents.
If I were reading it, I guess it would have put it in an byte array.

What is your answer to my question?:

Why would I create an array and put it into read method as an argument which belongs to a FileInputStreamer object that is referencing to a file ?

or I can put it this way:

Why would I ever use this method:
public int read(byte[] b)
that is found in a FileInputStream class ?

[Norm]

Why would I ever use this method:

To read bytes from a file.

[fatabass]

To read bytes from a file.

This method does not serve that purpose.

[Norm]

Are you telling me how the read method works?
What is the purpose of the read() method?

[fatabass]

not the read() method,

public int read(byte[] b) method..

[Norm]

read(byte[] b)

That is the method I'm talking about. The one you mentioned in post#25 and I answered in post #26

[fatabass]

That is the method I'm talking about.

Can you give an example then ? Maybe a few lines of code ?
How would you read bytes from a file using this method ? ( with the byte[] b argument )

[Norm]

There must be some examples here. Use Search to find them.
Or use Google.

Better yet, write you own code to read a few bytes into an array and use the Arrays class's toString() method to format that array for printing in a println statement.

[fatabass]

There is an answer to everything somewhere in the world.
No one should ask questions to anyone then.. ( Except it is something personal to a specific person.. Like where his wallet is or what his plans are.. )

And if you weren't going to help at the first time, why bother ?

[Norm]

You are going to have a hard time finding people to help you.

[fatabass]

It would have been so much easier if you could have provided a few lines of code.

Obviously I am struggling here, defining myself and understanding this method.

Anyway, difficult is done at once, impossible takes time..

I will find people to help me, believing is everything.. :)

Thanks for your efforts.

[Norm]

I'm surprised that Search or Google did not return samples.

[fatabass]

I did not try.

I really like personal connection.

I will just wait until I make some friends who knows JAVA.

Here's some lines of code. Hope it helps.

public static void main(String[] args) {

   doNotHelpList.add(fatabass);

   if (fatabass.senseOfEntitlement() <= REALISTIC_EXPECTATIONS) {
      doNotHelpList.remove(fatabass);
   }
}
