Class TextBlockExamples

java.lang.Object
net.jrodolfo.java_evolution.java15.TextBlockExamples
public class TextBlockExamples extends Object
Demonstrates text blocks, finalized in Java 15.

Before text blocks, multi-line strings required newline escapes, concatenation, and careful indentation. That made embedded JSON, SQL, HTML, and other structured text hard to read in Java source code.

Text blocks solve this by making multi-line string literals readable and maintainable. Java 15 finalized the feature after previews in Java 13 and Java 14.
