Question

Is it possible to convert strongly-typed data to bytes using the ByteBuffer class? If not, what is its main purpose? If yes, I am looking at its documentation and can find nothing. The put methods require a byte and not an int fro example.

Answer 1

Erm, you mean like …

String foo = "My String";
ByteBuffer myBuffer = ByteBuffer.wrap(foo.getBytes());

EDIT: For an int you can do…

int i = 1234;
ByteBuffer b = ByteBuffer.allocate(4);
b.putInt(i);
