SIMPLE EXAMPLE: String name = "Dave"; System.out.println("Hello, {name}!");

It shoud be noted that Groovy uses

 "Hello, ${name}!"

and Fan uses

 "Hello, $name!"

For Java, I'd always thought of going down the route of:

 <span class="katex"><span class="katex-mathml"><math xmlns="http://www.w3.org/1998/Math/MathML"><semantics><mrow><mi mathvariant="normal">&quot;</mi><mi>H</mi><mi>e</mi><mi>l</mi><mi>l</mi><mi>o</mi><mo separator="true">,</mo></mrow><annotation encoding="application/x-tex">&quot;Hello, </annotation></semantics></math></span><span class="katex-html" aria-hidden="true"><span class="base"><span class="strut" style="height:0.8889em;vertical-align:-0.1944em;"></span><span class="mord">&quot;</span><span class="mord mathnormal">He</span><span class="mord mathnormal" style="margin-right:0.01968em;">ll</span><span class="mord mathnormal">o</span><span class="mpunct">,</span></span></span></span>{name}!"

ie. a $ prefix to the string.

I know why the { notation is used, I ust think that staying in line with other close relative languages is important too.

IMO, its a lot more readable.
