Class TextBlockPreviewExamples

java.lang.Object
net.jrodolfo.java_evolution.java13.TextBlockPreviewExamples
public class TextBlockPreviewExamples extends Object
Demonstrates text blocks as a Java 13 preview feature.

Before text blocks, multi-line strings required repeated quotes, newline escapes, concatenation, and manual indentation. That made embedded JSON, SQL, HTML, and XML harder to read.

Java 13 previewed text blocks to solve that readability problem. Text blocks became final later, in Java 15. This project compiles on JDK 25, so the example uses final syntax while documenting the Java 13 preview origin.
