java.util.HexFormat utility: - Format and parse hexadecimal strings, with parameters for delimiter, prefix, suffix and upper/lowercase - Static factories and builder methods to create HexFormat copies with modified parameters. - Consistent naming of methods for conversion of byte arrays to formatted strings and back: formatHex and parseHex - Consistent naming of methods for conversion of primitive types: toHexDigits... and fromHexDigits... - Prefix and suffixes now apply to each formatted value, not the string as a whole - Using java.util.Appendable as a target for buffered conversions so output to Writers and PrintStreams like System.out are supported in addition to StringBuilder. (IOExceptions are converted to unchecked exceptions) - Immutable and thread safe, a "value-based" class
