Class OctalUtil


  • public final class OctalUtil
    extends Object

    The OctalUtil class is a final class that provides static methods for converting octal values in string representation as bits to a Java's Primitive Data Type.

    Currently this class supports converting octal values in string representation to integer int values and integer long values.

    This class treats octal strings as bit values represented by octal digits and not real numbers. Thus, octal strings parse by this class will be converted to the suppored data types as if they were real bit values represented by octal digits.

    To treats octal values as signed or unsigned real base 8 numbers use Base8Util.

      • toInt

        public static int toInt​(String input)
        Parse the input string as bits represented by octal digits to an integer int value.
        Parameters:
        input - A string to be parsed as octal digits to an interger int value.
        Returns:
        An integer int value of the octal input string.
        Throws:
        NumberFormatException - If the input string contains invalid octal digits, or if the input string contains a value that is beyond 32 bits. Leading zeroes do not count.
        EmptyStringException - If the input string is empty.

      • toLong

        public static long toLong​(String input)
        Parse the input string as bits represented by octal digits to an integer long value.
        Parameters:
        input - A string to be parsed as octal digits to an interger long value.
        Returns:
        An integer long value of the octal input string.
        Throws:
        NumberFormatException - If the input string contains invalid octal digits, or if the input string contains a value that is beyond 64 bits. Leading zeroes do not count.
        EmptyStringException - If the input string is empty.
