25.55 java.lang.Short (JDK 1.1)

This class provides an object wrapper around the short primitive type. It defines useful constants for the minimum and maximum values that can be stored by the short type, and also a Class object constant that represents the short type. It also provides various methods for converting Short values to and from strings and other numeric types.

Most of the static methods of this class are used to convert a String to a Short object or a short value: the four parseShort() and valueOf() methods parse a number from the specified string, using an optionally specified radix, and return it in one of these two forms. The decode() method parses a number specified in base 10, base 8, or base 16 and returns it as a Short. If the string begins with "0x" or "#", it is interpreted as a hexadecimal number, or if it begins with "0", it is interpreted as an octal number. Otherwise, it is interpreted as a decimal number.

Note that this class has two different toString() methods. One is static and converts a short primitive value to a String. The other is the usual toString() method that converts a Short object to a string. Most of the remaining methods convert a Short to various primitive numeric types.

            public Short(String s) throws NumberFormatException;
    // Constants

            public static final short MIN_VALUE;
            public static final Class TYPE;
    // Class Methods
            public static Short decode(String nm) throws NumberFormatException;
            public static short parseShort(String s) throws NumberFormatException;
            public static short parseShort(String s, int radix) throws NumberFormatException;
            public static String toString(short s);
            public static Short valueOf(String s, int radix) throws NumberFormatException;
            public static Short valueOf(String s) throws NumberFormatException;
    // Public Instance Methods
