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