Prior to text block you would write the same as shown below.
Java text blocks code#
Text Blocks are multi-line string literals that make our code easier to read and write, with more predictable formatting. Java Text Blocks are Java 15's solution to these problems. Example:Īssign a JSON to a string as a text block. Java Text Blocks are Java 15s solution to these problems. Prior to Java 13, you’d either use String concatenation or a StringBuilder in order to create a multiline String. However, it is most definitely not a pretty sight, nor is it a pleasure to read. Now let's explore why text blocks were added and what they can do. Since it's now an official part of the language, you can start using it in production code, and the feature is here to stay. Text blocks started out as a preview feature in the Java language, but it now has graduated to be part of the Java language specification. What are text blocks ?Ī text block is a multi-line string literal that avoids the need for most escape sequences, automatically formats the string in a predictable way, and gives the developer control over the format when desired. Let's dive into the text blocks language feature.
But how exactly is 'common white space prefix' defined in the case that lines are indented using mix of tabs. It allows to define multi-lined string literals without breaking code indentation, by stripping the common white space prefix from the lines. Text blocks were initially planned for Java 12 but this feature generated a lot of debates inside the Java Community and its introduction has been. It was a preview feature in Java 13, 14 and became final and permanent in Java 15. Java 15 introduced (non-preview) text blocks feature. Another interesting feature that was added to Java is the text blocks.
