Multi-Line Strings (Text Blocks)

This lesson covers writing a multi-line string with Java's text blocks, so you can build a readable message. It's for anyone searching "Java text block usage."

Wrapping text in three double quotes lets you write a multi-line string (a text block) that includes line breaks directly. It's a relatively recent Java feature, handy for writing something like an email body or a long explanation readably.

The example includes a %s placeholder inside a text block, filling it in with a variable using .formatted(name). It builds a 3-line message — a greeting, a thank-you, and a closing — with the line breaks included directly.

A common early mistake is how text blocks handle indentation. The leading whitespace at the start gets automatically stripped, which behaves differently from a regular string and takes some getting used to.

In real projects, this is used a lot for building readable text like SQL statements or JSON — anywhere you're constructing a long piece of text.
