Without text blocks, we would have to have written: String address = "25 Main Street\n" + In this simple example, the variable address will contain a two-line string, with line terminators after each line. A text block looks like: String address = """ Text blocks are string literals that can comprise multiple lines of text. It was subsequently refined in a second preview, with minor changes, and is scheduled to become a permanent feature of the Java Language in Java SE 15(Sept 2020). Java SE 13 (Sept 2019) introduced text blocks as a preview feature, aimed at reducing the pain of declaring and using multi-line string literals in Java. In this article, he dives into Text Blocks. In Java Futures at QCon New York, Java Language Architect Brian Goetz took us on a whirlwind tour of some of the recent and future features in the Java Language. To ensure adequate time for experimentation and feedback under the newer rapid release cadence, new language features will go through one or more rounds of preview, where they are part of the platform, but must be separately opted into, and which are not yet permanent - so that in the event they need to be adjusted based on feedback from developers, this is possible without breaking mission-critical code. When Java had multi-year release cycles, there was plenty of time for experimentation and feedback. The ultimate proving ground for language features is actual use feedback from developers who have actually tried them out on real codebases is essential to ensure that the feature is working as intended. In the context of a language misfeature, the commitment to compatibility not only means it is very difficult to remove or significantly change the feature, but existing features also constrain what future features can do - today's shiny new features are tomorrow's compatibility constraints. Given the global reach and high compatibility commitments of the Java platform, the cost of a design mistake in a language feature is very high.
