Questions tagged [java-text-blocks]

A text block is a multi-line string literal feature in Java 15 and later. 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.

The Text Blocks feature is built into Java 15, after having been previewed in Java 12, 13, & 14.

See the specifications:
