Hello Everyone!
I am having problems trying to pass data through streams.
The Output streams I do not think are letting me pass data that is not of primitive type. I was trying to pass a byte[] and it was coming up null everytime on the other end. My idea is to pass in a loop a bunch of bytes and then put them into a bytearray on the other side. To me it makes sense. I have had some issues trying to perform this conversion.

It is possible to convert several bytes into a byte[] array, correct?

Thanks a lot,

Of course you can, and the problem must be something else.

Which stream class did you use and which method of that class did you call?

Thanks for your reply,

I have a few classes that I am working with. Basically troubleshooting the first problem that I come across I am faced with a Java.lang.NullPointerException.

static byte pDatabyte[];
static char charTest = 'a';
static byte test2;

for (int index = 0; index < dataLength; index++) {

test2= (byte) charTest;
//s.setTestByte(test2) I will use once I get everything else working
pDatabyte[index] = test2;

}

This is my first problem that I came across. The compiler hits a NullPointerException
error and points to my line 54 which is the only error line it hits
pDatabyte[index] = test2; line

For simplicity I just show those first few lines.
Thanks a lot!

After a few minutes working on it I see what I did wrong. I have to initialize the byte array first instead of just declaring it. Simple problem but I thank you for your reply as well.

static byte[] pDatabyte = new pDatabyte[100];


Thanks

Glad that you resolved this. Yes, you have to initialize it first, one big source of null pointer is this.
