What is the Ideal Way to Convert an Integer to a String in Groovy

Question

In plain old Java, there are many ways to convert an integer to a string, such that 5 becomes "5". The answers in this post have several good suggestions, String.valueOf(number) being my favorite.

My question is does Groovy provide a different/better way to do this? Or is the Java method still the way to go.

Does toString() work for you? It looks pretty descriptive to me, and it beats out ''+5 performance-wise.

Integer x = 5;
System.out.println(x.toString());

Depending on your use case, you can do this very simply with a GString:

String str = "$number"
