question: public static byte parseByte ( java . lang . String s , int radix ) throws java . lang . NumberFormatException { int intValue = Integer . parseInt ( s , radix ) ; byte result = ( byte ) intValue ; if ( result == intValue ) { return result ; } throw new NumberFormatException ( "Value out of range for byte: \"" + s + "\"" ) ; }
target:  Assuming the specified String represents a byte, returns that byte's value. Throws an exception if the String cannot be parsed as a byte.
