Question

If I use int oneByte = dis.read(byteArray, 0, 1) does this mean I am reading only 1 byte and I am assigning its decimal value to integer oneByte?

If I want to check for | (pipe) character to break out of a loop can I do something like this:
while((oneByte = dis.read(byteArray, 0, 1)) != 124)

If I use int oneByte = dis.read(byteArray, 0, 1) does this mean I am
reading only 1 byte and I am assigning its decimal value to integer
oneByte?

Nope. You’re reading up to 1 bytes into byteArray and receiving the number of bytes read in oneByte. Perhaps you’d prefer:

int oneByte = dis.read();

Also be careful because you’ll get the integer value…not a decimal. Keep in mind that it will return -1 when you reach the end of the stream.

124)

You’ll need to also check for the end of stream (-1). Try something more like this:

while(true) {
    int oneByte = dis.read();
    if(oneByte == -1 || oneByte == '|') {
        break;
    }
}
