public final class Short
`` extends [Number](/reference/java/lang/Number) implements[Comparable](/reference/java/lang/Comparable)<[Short](/reference/java/lang/Short)>

The Short class wraps a value of primitive type short in an object. An object of type Short contains a single field whose type is short.

In addition, this class provides several methods for converting a short to a String and a String to ashort, as well as other constants and methods useful when dealing with a short.

Public constructors

Short

public Short (String s)

This constructor is deprecated.
It is rarely appropriate to use this constructor. Use [parseShort(java.lang.String)](/reference/java/lang/Short#parseShort%28java.lang.String%29) to convert a string to ashort primitive, or use [valueOf(java.lang.String)](/reference/java/lang/Short#valueOf%28java.lang.String%29) to convert a string to a Short object.

Constructs a newly allocated Short object that represents the short value indicated by theString parameter. The string is converted to ashort value in exactly the manner used by theparseShort method for radix 10.

Short

public Short (short value)

This constructor is deprecated.
It is rarely appropriate to use this constructor. The static factory[valueOf(short)](/reference/java/lang/Short#valueOf%28short%29) is generally a better choice, as it is likely to yield significantly better space and time performance.

Constructs a newly allocated Short object that represents the specified short value.

Public methods

byteValue

public byte byteValue ()

Returns the value of this Short as a byte after a narrowing primitive conversion.

compare

public static int compare (short x, short y)

Compares two short values numerically. The value returned is identical to what would be returned by:

Short.valueOf(x).compareTo(Short.valueOf(y))

compareTo

public int compareTo (Short anotherShort)

Compares two Short objects numerically.

compareUnsigned

public static int compareUnsigned (short x, short y)

Compares two short values numerically treating the values as unsigned.

decode

public static Short decode (String nm)

Decodes a String into a Short. Accepts decimal, hexadecimal, and octal numbers given by the following grammar:

DecodableString:

Signopt DecimalNumeral

Signopt 0x HexDigits

Signopt 0X HexDigits

Signopt # HexDigits

Signopt 0 OctalDigits

Sign:

-

+

DecimalNumeral, HexDigits, and OctalDigits are as defined in section {@jls 3.10.1} ofThe Java Language Specification, except that underscores are not accepted between digits.

The sequence of characters following an optional sign and/or radix specifier ("0x", "0X", "#", or leading zero) is parsed as by the Short.parseShort method with the indicated radix (10, 16, or 8). This sequence of characters must represent a positive value or a [NumberFormatException](/reference/java/lang/NumberFormatException) will be thrown. The result is negated if first character of the specified String is the minus sign. No whitespace characters are permitted in the String.

doubleValue

public double doubleValue ()

Returns the value of this Short as a double after a widening primitive conversion.

equals

public boolean equals (Object obj)

Compares this object to the specified object. The result istrue if and only if the argument is notnull and is a Short object that contains the same short value as this object.

floatValue

public float floatValue ()

Returns the value of this Short as a float after a widening primitive conversion.

hashCode

public static int hashCode (short value)

Returns a hash code for a short value; compatible withShort.hashCode().

hashCode

public int hashCode ()

Returns a hash code for this Short; equal to the result of invoking intValue().

intValue

public int intValue ()

Returns the value of this Short as an int after a widening primitive conversion.

longValue

public long longValue ()

Returns the value of this Short as a long after a widening primitive conversion.

parseShort

public static short parseShort (String s)

Parses the string argument as a signed decimal short. The characters in the string must all be decimal digits, except that the first character may be an ASCII minus sign '-' ('\u002D') to indicate a negative value or an ASCII plus sign '+' ('\u002B') to indicate a positive value. The resulting short value is returned, exactly as if the argument and the radix 10 were given as arguments to the [parseShort(java.lang.String, int)](/reference/java/lang/Short#parseShort%28java.lang.String,%20int%29) method.

parseShort

public static short parseShort (String s, int radix)

Parses the string argument as a signed short in the radix specified by the second argument. The characters in the string must all be digits, of the specified radix (as determined by whether [Character.digit(char, int)](/reference/java/lang/Character#digit%28char,%20int%29) returns a nonnegative value) except that the first character may be an ASCII minus sign '-' ('\u002D') to indicate a negative value or an ASCII plus sign '+' ('\u002B') to indicate a positive value. The resulting short value is returned.

An exception of type NumberFormatException is thrown if any of the following situations occurs:

• The first argument is null or is a string of length zero.
• The radix is either smaller than [Character.MIN_RADIX](/reference/java/lang/Character#MIN%5FRADIX) or larger than [Character.MAX_RADIX](/reference/java/lang/Character#MAX%5FRADIX).
• Any character of the string is not a digit of the specified radix, except that the first character may be a minus sign '-' ('\u002D') or plus sign'+' ('\u002B') provided that the string is longer than length 1.
• The value represented by the string is not a value of typeshort.

reverseBytes

public static short reverseBytes (short i)

Returns the value obtained by reversing the order of the bytes in the two's complement representation of the specified short value.

shortValue

public short shortValue ()

Returns the value of this Short as ashort.

toString

public static String toString (short s)

Returns a new String object representing the specified short. The radix is assumed to be 10.

toString

public String toString ()

Returns a String object representing thisShort's value. The value is converted to signed decimal representation and returned as a string, exactly as if the short value were given as an argument to the[toString(short)](/reference/java/lang/Short#toString%28short%29) method.

toUnsignedInt

public static int toUnsignedInt (short x)

Converts the argument to an int by an unsigned conversion. In an unsigned conversion to an int, the high-order 16 bits of the int are zero and the low-order 16 bits are equal to the bits of the short argument. Consequently, zero and positive short values are mapped to a numerically equal int value and negative short values are mapped to an int value equal to the input plus 216.

toUnsignedLong

public static long toUnsignedLong (short x)

Converts the argument to a long by an unsigned conversion. In an unsigned conversion to a long, the high-order 48 bits of the long are zero and the low-order 16 bits are equal to the bits of the short argument. Consequently, zero and positive short values are mapped to a numerically equal long value and negative short values are mapped to a long value equal to the input plus 216.

valueOf

public static Short valueOf (String s)

Returns a Short object holding the value given by the specified String. The argument is interpreted as representing a signed decimalshort, exactly as if the argument were given to the [parseShort(java.lang.String)](/reference/java/lang/Short#parseShort%28java.lang.String%29) method. The result is a Short object that represents theshort value specified by the string.

In other words, this method returns a Short object equal to the value of:

new Short(Short.parseShort(s))

valueOf

public static Short valueOf (short s)

Returns a Short instance representing the specifiedshort value. If a new Short instance is not required, this method should generally be used in preference to the constructor[Short(short)](/reference/java/lang/Short#Short%28short%29), as this method is likely to yield significantly better space and time performance by caching frequently requested values. This method will always cache values in the range -128 to 127, inclusive, and may cache other values outside of this range.

valueOf

public static Short valueOf (String s, int radix)

Returns a Short object holding the value extracted from the specified String when parsed with the radix given by the second argument. The first argument is interpreted as representing a signed short in the radix specified by the second argument, exactly as if the argument were given to the [parseShort(java.lang.String, int)](/reference/java/lang/Short#parseShort%28java.lang.String,%20int%29) method. The result is a Short object that represents the short value specified by the string.

In other words, this method returns a Short object equal to the value of:

new Short(Short.parseShort(s, radix))
