Method Detail isAlpha public static boolean isAlpha(int c)(Code) Returns true if the specified ASCII character is upper or lower case. isDigit public static boolean isDigit(int c)(Code) Returns true if the specified ASCII character is a digit. isLower public static boolean isLower(int c)(Code) Returns true if the specified ASCII character is lower case. isUpper public static boolean isUpper(int c)(Code) Returns true if the specified ASCII character is upper case. isWhite public static boolean isWhite(int c)(Code) Returns true if the specified ASCII character is white space. parseInt public static int parseInt(byte[] b, int off, int len) throws NumberFormatException(Code) Parses an unsigned integer from the specified subarray of bytes. Parameters:   b - the bytes to parse Parameters:   off - the start offset of the bytes Parameters:   len - the length of the bytes exception:   NumberFormatException - if the integer format was invalid parseInt public static int parseInt(char[] b, int off, int len) throws NumberFormatException(Code) parseLong public static long parseLong(byte[] b, int off, int len) throws NumberFormatException(Code) Parses an unsigned long from the specified subarray of bytes. Parameters:   b - the bytes to parse Parameters:   off - the start offset of the bytes Parameters:   len - the length of the bytes exception:   NumberFormatException - if the long format was invalid parseLong public static long parseLong(char[] b, int off, int len) throws NumberFormatException(Code) toLower public static int toLower(int c)(Code) Returns the lower case equivalent of the specified ASCII character. toUpper public static int toUpper(int c)(Code) Returns the upper case equivalent of the specified ASCII character.
