11. 42. ByteBuffer
11. 42. 1. A ByteBuffer is a fixed-capacity buffer that holds byte values.
11. 42. 2. Create a ByteBuffer using a byte array
11. 42. 3. Create a non-direct ByteBuffer with a 10 byte capacity
11. 42. 4. Create a direct (memory-mapped) ByteBuffer with a 10 byte capacity.
11. 42. 5. Allocation automatically zeroes the ByteBuffer
11. 42. 6. Store and read a char array
11. 42. 7. Store and read a short
11. 42. 8. Rewind a ByteBuffer
11. 42. 9. Store and read an int
11. 42. 10. Store and read a long
11. 42. 11. Store and read a float
11. 42. 12. Store and read a double
11. 42. 13. ByteBuffer.hasRemaining()
11. 42. 14. Use while loop to read a ByteBuffer
11. 42. 15. Retrieve all bytes in the buffer
11. 42. 16. Retrieve bytes between the position and limit
11. 42. 17. Converting text to and from ByteBuffers with UTF-16BE
11. 42. 18. Converting text to and from ByteBuffers
11. 42. 19. Get the ByteBuffer's capacity
11. 42. 20. Use the absolute get().
11. 42. 21. Set the position
11. 42. 22. Use the relative get()
11. 42. 23. Get remaining byte count in a ByteBuffer
11. 42. 24. Set the limit for ByteBuffer
11. 42. 25. This convenience method sets the position to 0
11. 42. 26. Converting Between a ByteBuffer an a Byte Array
11. 42. 27. Putting Bytes into a ByteBuffer
11. 42. 28. Endian differences and data storage
11. 42. 29. Use FileChannel and ByteBuffer to Copy File
11. 42. 30. Read from a channel with a ByteBuffer
