```
    Returns the index of the first appearance of the value target in array.
    
    Parameters:
    array - an array of short values, possibly empty
    target - a primitive short value
    
    Returns:
    the least index i for which array[i] == target, or -1 if no such index exists.
  - indexOf
```
public static int indexOf(short[] array,
          short[] target)
```

    More formally, returns the lowest index i such that java.util.Arrays.copyOfRange(array, i, i + target.length) contains exactly the same elements as target.
    
    Parameters:
    array - the array to search for the sequence target
    target - the array to search for as a sub-sequence of array
  - lastIndexOf
```
public static int lastIndexOf(short[] array,
              short target)
```

    Parameters:
    array - an array of short values, possibly empty
    target - a primitive short value
    
    Returns:
    the greatest index i for which array[i] == target, or -1 if no such index exists.
  - min
```
public static short min(short... array)
```
    Returns the least value present in array.
    
    Parameters:
    array - a nonempty array of short values
    
    Returns:
    the value present in array that is less than or equal to every other value in the array
    
    Throws:
    
    IllegalArgumentException - if array is empty
  - max
```
public static short max(short... array)
```
    Returns the greatest value present in array.
    
    Parameters:
    array - a nonempty array of short values
    
    Returns:
    the value present in array that is greater than or equal to every other value in the array
    
    Throws:
    
    IllegalArgumentException - if array is empty
  - concat
```
public static short[] concat(short[]... arrays)
```
    Returns the values from each provided array combined into a single array. For example, concat(new short[] {a, b}, new short[] {}, new short[] {c} returns the array {a, b, c}.
    
    Parameters:
    arrays - zero or more short arrays
    
    Returns:
    a single array containing all the values from the source arrays, in order
  - toByteArray
```
@GwtIncompatible(value="doesn\'t work")
public static byte[] toByteArray(short value)
```
    Returns a big-endian representation of value in a 2-element byte array; equivalent to ByteBuffer.allocate(2).putShort(value).array(). For example, the input value (short) 0x1234 would yield the byte array {0x12, 0x34}.
    If you need to convert and concatenate several values (possibly even of different types), use a shared ByteBuffer instance, or use ByteStreams.newDataOutput() to get a growable buffer.
  - fromByteArray
```
@GwtIncompatible(value="doesn\'t work")
public static short fromByteArray(byte[] bytes)
```
    Returns the short value whose big-endian representation is stored in the first 2 bytes of bytes; equivalent to ByteBuffer.wrap(bytes).getShort(). For example, the input byte array {0x54, 0x32} would yield the short value 0x5432.
    Arguably, it's preferable to use ByteBuffer; that library exposes much more flexibility at little cost in readability.
    
    Throws:
    
    IllegalArgumentException - if bytes has fewer than 2 elements
  - fromBytes
```
@GwtIncompatible(value="doesn\'t work")
public static short fromBytes(byte b1,
                                   byte b2)
```
    Returns the short value whose byte representation is the given 2 bytes, in big-endian order; equivalent to Shorts.fromByteArray(new byte[] {b1, b2}).
    
    Since:
    
    7.0
  - ensureCapacity
```
public static short[] ensureCapacity(short[] array,
                     int minLength,
                     int padding)
```
    Returns an array containing the same values as array, but guaranteed to be of a specified minimum length. If array already has a length of at least minLength, it is returned directly. Otherwise, a new array of size minLength + padding is returned, containing the values of array, and zeroes in the remaining places.
    
    Parameters:
    array - the source array
    minLength - the minimum length the returned array must guarantee
    padding - an extra amount to "grow" the array by if growth is necessary
    
    Returns:
    an array containing the values of array, with guaranteed minimum length minLength
    
    Throws:
    
    IllegalArgumentException - if minLength or padding is negative
  - join
```
public static String join(String separator,
          short... array)
```
    Returns a string containing the supplied short values separated by separator. For example, join("-", (short) 1, (short) 2, (short) 3) returns the string "1-2-3".
    
    Parameters:
    separator - the text that should appear between consecutive values in the resulting string (but not at the start or end)
    array - an array of short values, possibly empty
  - lexicographicalComparator
```
public static Comparator<short[]> lexicographicalComparator()
```
    Returns a comparator that compares two short arrays lexicographically. That is, it compares, using compare(short, short)), the first pair of values that follow any common prefix, or when one array is a prefix of the other, treats the shorter array as the lesser. For example, [] < [(short) 1] < [(short) 1, (short) 2] < [(short) 2].
    The returned comparator is inconsistent with Object.equals(Object) (since arrays support only identity equality), but it is consistent with Arrays.equals(short[], short[]).
    
    Since:
    
    2.0

  - toArray
```
public static short[] toArray(Collection<? extends Number> collection)
```
    Returns an array containing each value of collection, converted to a short value in the manner of Number.shortValue().
    Elements are copied from the argument collection as if by collection.toArray(). Calling this method is as thread-safe as calling that method.
    
    Parameters:
    collection - a collection of Number instances
    
    Returns:
    an array containing the same values as collection, in the same order, converted to primitives
    
    Throws:
    
    NullPointerException - if collection or any of its elements is null
    Since:
    
    1.0 (parameter was Collection<Short> before 12.0)
  - asList
```
public static List<Short> asList(short... backingArray)
```
    Returns a fixed-size list backed by the specified array, similar to Arrays.asList(Object[]). The list supports List.set(int, Object), but any attempt to set a value to null will result in a NullPointerException.
    The returned list maintains the values, but not the identities, of Short objects written to or read from it. For example, whether list.get(0) == list.get(0) is true for the returned list is unspecified.
    
    Parameters:
    backingArray - the array to back the list
    
    Returns:
    a list view of the array
