Java 21 does have interpolated strings thanks to JEP 430. In [[JShell|jshell]] you could use the constant STR of [https://docs.oracle.com/en/java/javase/21/docs/api/java.base/java/lang/StringTemplate.html java.lang.StringTemplate] directly.<syntaxhighlight lang="java" line="1">

{{as of|2022}}, Java does not have interpolated strings, and instead uses format functions, notably the <code>MessageFormat</code> class (Java version 1.1 and above) and the static method <code>String.format</code> (Java version 5 and above).

This proposal aims at doing safe string interpolation, making it easier to prevent injection attacks.

enum Stage{test,qa,prod}

record Deploy(UUID image, Stage stage){}

var deploy=new Deploy(UUID.randomUUID(), Stage.test)

STR."Installing \{deploy.image()} on Stage \{deploy.stage()} ..."

var deploy=new Deploy(UUID.randomUUID(), Stage.prod)

STR."Installing \{deploy.image()} on Stage \{deploy.stage()} ..."
