New as of JDK 1.1
The Short class provides an object wrapper for a short value. This is useful when you need to treat a short value as an object. For example, there are a number of utility methods that take a reference to an Object as one of their arguments. You cannot specify a short value for one of these arguments, but you can provide a reference to a Short object that encapsulates the byte value. Furthermore, the Short class is necessary as of JDK 1.1 to support the Reflection API and class literals.
The Short class also provides a number of utility methods for converting short values to other primitive types and for converting short values to strings and vice-versa.
public final class java.lang.Short extends java.lang.Number {
// Constants
public static final short MAX_VALUE;
public static final short MIN_VALUE;
public static final Class TYPE;
// Constructors
public Short(short value);
public Short(String s);
// Class Methods
public static Short decode(String nm);
public static short parseShort(String s);
public static short parseShort(String s, int radix);
public static String toString(short s);
public static Short valueOf(String s, int radix);
public static Short valueOf(String s);
// Instance Methods
public byte byteValue();
public double doubleValue();
public boolean equals(Object obj);
public float floatValue();
public int hashCode();
public int intValue();
public long longValue();
public short shortValue();
public String toString();
}
The largest value that can be represented by a short.
The smallest value that can be represented by a short.
The Class object that represents the primitive type short. It is always true that Short.TYPE == short.class.
The short value to be encapsulated by this object.
Creates a Short object with the specified short value.
The string to be made into a Short object.
If the sequence of characters in the given String does not form a valid short literal.
Constructs a Short object with the value specified by the given string. The string should consist of one or more digit characters. The digit characters can be preceded by a single `-' character. If the string contains any other characters, the constructor throws a NumberFormatException.
A String representation of the value to be encapsulated by a Short object. If the string begins with # or 0x, it is a radix 16 representation of the value. If the string begins with 0, it is a radix 8 representation of the value. Otherwise, it is assumed to be a radix 10 representation of the value.
A Short object that encapsulates the given value.
If the String contains any non-digit characters other than a leading minus sign or the value represented by the String is less than Short.MIN_VALUE or greater than Short.MAX_VALUE.
This method returns a Short object that encapsulates the given value.
public static short parseShort(String s) throws NumberFormatException
The String to be converted to a short value.
The numeric value of the short represented by the String object.
If the String does not contain a valid representation of a short or the value represented by the String is less than Short.MIN_VALUE or greater than Short.MAX_VALUE.
This method returns the numeric value of the short represented by the contents of the given String object. The String must contain only decimal digits, except that the first character may be a minus sign.
public static short parseShort(String s, int radix) throws NumberFormatException
The String to be converted to a short value.
The radix used in interpreting the characters in the String as digits. This value must be in the range Character.MIN_RADIX to Character.MAX_RADIX. If radix is in the range 2 through 10, only characters for which the Character.isDigit() method returns true are considered to be valid digits. If radix is in the range 11 through 36, characters in the ranges `A' through `Z' and `a' through `z' are considered valid digits.
The numeric value of the short represented by the String object in the specified radix.
If the String does not contain a valid representation of a short, radix is not in the appropriate range, or the value represented by the String is less than Short.MIN_VALUE or greater than Short.MAX_VALUE.
This method returns the numeric value of the short represented by the contents of the given String object in the specified radix. The String must contain only valid digits of the specified radix, except that the first character may be a minus sign. The digits are parsed in the specified radix to produce the numeric value.
The short value to be converted to a string.
The string representation of the given value.
This method returns a String object that contains the decimal representation of the given value.
This method returns a string that begins with `-' if the given value is negative. The rest of the string is a sequence of one or more of the characters `0', `1', `2', `3', `4', `5', `6', `7', `8', and `9'. This method returns "0" if its argument is 0. Otherwise, the string returned by this method does not begin with "0" or "-0".
The string to be made into a Short object.
The Short object constructed from the string.
If the String does not contain a valid representation of a short or the value represented by the String is less than Short.MIN_VALUE or greater than Short.MAX_VALUE.
Constructs a Short object with the value specified by the given string. The string should consist of one or more digit characters. The digit characters can be preceded by a single `-'. If the string contains any other characters, the method throws a NumberFormatException.
public static Short valueOf(String s, int radix) throws NumberFormatException
The string to be made into a Short object.
The radix used in converting the string to a value. This value must be in the range Character.MIN_RADIX to Character.MAX_RADIX.
The Short object constructed from the string.
If the String does not contain a valid representation of a short, radix is not in the appropriate range, or the value represented by the String is less than Short.MIN_VALUE or greater than Short.MAX_VALUE.
Constructs a Short object with the value specified by the given string in the specified radix. The string should consist of one or more digit characters or characters in the range `A' to `Z' or `a' to `z' that are considered digits in the given radix. The digit characters can be preceded by a single `-' character. If the string contains any other characters, the method throws a NumberFormatException.
The value of this object as a byte. The high order bits of the value are discarded.
Number.byteValue()
This method returns the value of this object as a byte.
The value of this object as a double.
Number.doubleValue()
This method returns the value of this object as a double.
The object to be compared with this object.
true if the objects are equal; false if they are not.
Object.equals()
This method returns true if obj is an instance of Short and it contains the same value as the object this method is associated with.
The value of this object as a float.
Number.floatValue()
This method returns the value of this object as a float.
A hashcode based on the short value of the object.
Object.hashCode()
This method returns a hash code computed from the value of this object.
The value of this object as an int.
Number.intValue()
This method returns the value of this object as an int.
The value of this object as a long.
Number.longValue()
This method returns the value of this object as a long.
The value of this object as a short.
Number.shortValue()
This method returns the value of this object as a short.
The string representation of the value of this object.
Object.toString()
This method returns a String object that contains the decimal representation of the value of this object.
This method returns a string that begins with `-' if the value is negative. The rest of the string is a sequence of one or more of the characters `0', `1', `2', `3', `4', `5', `6', `7', `8', and `9'. This method returns "0" if the value of the object is 0. Otherwise, the string returned by this method does not begin with "0" or "-0".
