Java Text Blocks: Making Multi-line Strings Easier to Read and Write

Java 13 introduced a new feature called “text blocks,” which makes it much easier to write and read multi-line strings in Java code. In this article, I’ll introduce the concept of text blocks, discuss their benefits, and provide some examples of how to use them in your own Java code.

A 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.

Traditionally, multi-line strings have been represented as a series of concatenated string literals, which can be cumbersome to write and difficult to read.

There are several benefits to using text blocks in your Java code. First, text blocks can make your code much easier to read and understand, especially when dealing with large or complex strings.

Example of useful use cases using Java text blocks
