A text block is a multi-line string literal and the feature offers a clean way to format the string in a predictable way, without using most of the escape sequences. Java 12 introduces text blocks to handle multiline strings like JSON/XML/HTML etc and added new methods to String class to handle text blocks. The end of block quotes can end in the same line as the text of in a new line: String thisIsValid = """ This topic is about Java 13 Text Block Methods.

Text Blocks are a JDK Enhancement Proposal ( JEP 355) available as preview language feature in JDK 13 and 14. Lets quickly look at the different ways of creating multiline strings: String aBlock = """ Java 12 introduces text blocks to handle multiline strings like JSON/XML/HTML etc and added new methods to String class to handle text blocks. This allows writing multiline strings easily without the need for concatenation while splitting into different lines. 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. One of the new features is “text blocks”.

If we look underneath, we can see that this is effectively just a convenience for Java 1.5’s Formatter: public String formatted(Object.Home › Java › JEP 355 Text Blocks in JDK 13 ("Hello %s!".formatted("World")) // Hello World! This method allows us to conveniently format the provided String template with given arguments – think non-static String#format. This, in turn, creates demand for additional String methods that complement the new syntax.
