WebWriting zeros and reading in fixed-length blocks is obviously not very interesting. We want to prepare our byte array with some actual content. A common way to prepare byte arrays is to use a ByteBuffer, filling it with data from various types. Let’s assume we want to write "strings" in the following format:

WebBuffering: if you grab 1024 bytes at a time and start a sequence at element 1022 you will hit the end of the buffer before you get 4 bytes. It's probably better to use some form of buffered input stream that does the buffered automatically so you can just use readByte () repeatedly and not worry about it otherwise; WebThe compiler hints are not necessary. They are just a clarification in this example.
