Java map replace one-ot-one

Question

For example, I have a String "PARAMS @ FOO @ BAR @" and String array {"one", "two", "three"}.

How would you map the array values one-to-one to the string (replace the markers), so that in the end I would get: "PARAMS one, FOO two, BAR three".

Thank you

You could just do

String str =  "PARAMS @ FOO @ BAR @";
String[] arr = {"one", "two", "three"};

for (String s : arr)
    str = str.replaceFirst("@", s);

After this, str would hold "PARAMS one FOO two BAR three". Of course, to include the commas you could just replace with s + ",".
