Putting Bytes into a ByteBuffer


 



import java.nio.ByteBuffer;



public class Main {

  public static void main(String[] argv) throws Exception {

    ByteBuffer bbuf = ByteBuffer.allocate(10);

    int capacity = bbuf.capacity(); // 10

    System.out.println(capacity);

    bbuf.put((byte) 0xFF); 

    bbuf.position(5);

    bbuf.put((byte) 0xFF);

    int pos = bbuf.position(); 

    int rem = bbuf.remaining();

    bbuf.limit(7); 

    bbuf.rewind();
