| Package | Description | 
|---|---|
| java.nio | Defines buffers, which are containers for data, and provides an overview of the
other NIO packages. | 
| java.util | Contains the collections framework, legacy collection classes, event model,
date and time facilities, internationalization, and miscellaneous utility
classes (a string tokenizer, a random-number generator, and a bit array). | 
| Modifier and Type | Method and Description | 
|---|---|
| static LongBuffer | LongBuffer. allocate(int capacity)Allocates a new long buffer. | 
| abstract LongBuffer | ByteBuffer. asLongBuffer()Creates a view of this byte buffer as a long buffer. | 
| abstract LongBuffer | LongBuffer. asReadOnlyBuffer()Creates a new, read-only long buffer that shares this buffer's
 content. | 
| abstract LongBuffer | LongBuffer. compact()Compacts this buffer  (optional operation). | 
| abstract LongBuffer | LongBuffer. duplicate()Creates a new long buffer that shares this buffer's content. | 
| LongBuffer | LongBuffer. get(long[] dst)Relative bulk get method. | 
| LongBuffer | LongBuffer. get(long[] dst,
   int offset,
   int length)Relative bulk get method. | 
| abstract LongBuffer | LongBuffer. put(int index,
   long l)Absolute put method  (optional operation). | 
| abstract LongBuffer | LongBuffer. put(long l)Relative put method  (optional operation). | 
| LongBuffer | LongBuffer. put(long[] src)Relative bulk put method  (optional operation). |

   int length)Relative bulk put method  (optional operation). | 
| LongBuffer | LongBuffer. put(LongBuffer src)Relative bulk put method  (optional operation). | 
| abstract LongBuffer | LongBuffer. slice()Creates a new long buffer whose content is a shared subsequence of
 this buffer's content. | 
| static LongBuffer | LongBuffer. wrap(long[] array)Wraps a long array into a buffer. | 
| static LongBuffer | LongBuffer. wrap(long[] array,
    int offset,
    int length)Wraps a long array into a buffer. | 
| Modifier and Type | Method and Description | 
|---|---|
| int | LongBuffer. compareTo(LongBuffer that)Compares this buffer to another. | 
| LongBuffer | LongBuffer. put(LongBuffer src)Relative bulk put method  (optional operation). | 
| Modifier and Type | Method and Description | 
|---|---|
| static BitSet | BitSet. valueOf(LongBuffer lb)Returns a new bit set containing all the bits in the given long
 buffer between its position and limit. |
