Class HexFormatExamples

java.lang.Object
net.jrodolfo.java_evolution.java17.HexFormatExamples
public class HexFormatExamples extends Object
Demonstrates HexFormat, introduced in Java 17.

Before Java 17, converting bytes to hexadecimal text and parsing hexadecimal text back into bytes often required custom utility code or an external library.

HexFormat solves this small but common problem with a standard API that supports parsing, formatting, delimiters, prefixes, and suffixes.
