Class FilesApiExamples

java.lang.Object

net.jrodolfo.java_evolution.java11.FilesApiExamples

public class FilesApiExamples
extends Object

Demonstrates file convenience methods introduced in Java 11.

Before Java 11, reading or writing a whole text file often required byte arrays or extra charset-handling code. That was more ceremony than many simple text-file use cases needed.

Files.readString(Path) and Files.writeString(Path, CharSequence, java.nio.file.OpenOption...) solve the common whole-file text case directly.
