Java generating Strings with placeholders

Question

I\'m looking for something to achieve the following:

String s = \"hello {}!\";
s = generate(s, new Object[]{ \"world\" });
assertEquals(s, \"hello world!\");

You won't need a library; if you are using a recent version of Java, have a look at String.format:

String.format("Hello %s!", "world");
