Class StringApiExamples

java.lang.Object
net.jrodolfo.java_evolution.java11.StringApiExamples
public class StringApiExamples extends Object
Demonstrates String API additions introduced in Java 11.

Before Java 11, common string operations such as checking for blank text, splitting into lines, stripping Unicode-aware whitespace, and repeating text often required helper code or less precise alternatives.

Java 11 added small but useful methods for those cases: String.isBlank(), String.lines(), String.strip(), and String.repeat(int).
