809N/A * There are six methods in java.lang.Short which transform strings
809N/A * into a short or Short value:
809N/A *
809N/A * public Short(String s)
809N/A * public static Short decode(String nm)
809N/A * public static short parseShort(String s, int radix)
809N/A * public static short parseShort(String s)
809N/A * public static Short valueOf(String s, int radix)
809N/A * public static Short valueOf(String s)
809N/A *
809N/A * However, of these only decode has a nontrivial implementation
809N/A * in that class.
