Question

I would like to know if there is, in Java, a function that can prefix a defined String to the beginning of every String of an array of Strings.

For example,

my_function({"apple", "orange", "ant"}, "eat an ")  would return {"eat an apple", "eat an orange", "eat an ant"}

Currently, I coded this function, but I wonder if it already exists.

Answer 1

Nope. Since it should be about a three-line function, you’re probably better of just sticking with the one you coded.

Update

With Java 8, the syntax is simple enough I’m not even sure if it’s worth creating a function for:

List<String> eatFoods = foodNames.stream()
    .map(s -> "eat an " + s)
    .collect(Collectors.toList());
