An int buffer.
 This class defines four categories of operations upon
int buffers:

   Absolute and relative get and put methods that read and write single ints; 
   Relative bulk get methods that transfer contiguous sequences of ints from this buffer into an array; and
   Relative bulk put methods that transfer contiguous sequences of ints from an int array or some other int buffer into this buffer; and 
   A method for compacting an int buffer. 

 Int buffers can be created either by allocation, which allocates space for the buffer's content, by wrapping an existing int array into a buffer, or by creating a view of an existing byte buffer.
 Like a byte buffer, an int buffer is either direct or non-direct. A int buffer created via the wrap methods of this class will be non-direct. An int buffer created as a view of a byte buffer will be direct if, and only if, the byte buffer itself is direct. Whether or not an int buffer is direct may be determined by invoking the isDirect method. 
 Methods in this class that do not otherwise have a value to return are
specified to return the buffer upon which they are invoked.  This allows
method invocations to be chained.

    Retrieves this buffer's byte order.
 The byte order of an int buffer created by allocation or by wrapping an existing int array is the native order of the underlying hardware. The byte order of an int buffer created as a view of a byte buffer is that of the
byte buffer at the moment that the view is created.  
Returns:  This buffer's byte order/**
