Both dqName and tbName intern to the same string Continuing with dqName and tbName from the examples above, // Both dqName and tbName are strings of equal value This includes object representation and interning.

#JAVA 13 TEXT BLOCKS CODE#
Text blocks eliminate most of these obstructions, allowing you to embed code snippets and text sequences more or less as-is.Ī text block is an alternative form of Java string representation that can be used anywhere a traditional double quoted string literal can be used. In earlier releases of the JDK, embedding multi-line code snippets required a tangled mess of explicit line terminators, string concatenations, and delimiters. IntroductionĪ text block's principalis munus is to provide clarity by way of minimizing the Java syntax required to render a string that spans multiple lines.
This guide assembles practical usage advice for text blocks, along with some style guidelines. While the JEP explains the feature in great detail, it's not always apparent how the feature can and should be used.
JEP 378 adds the language feature text blocks to Java SE 15 and later. Detecting Potential Issues with White Space.
