How to replace a word?

Question

Java

In general, there is a String str variable that can contain a word, for example "LOG", only one word can be contained in this variable, I need this word to change to the specified one, let's say if str is equal to the word "LOG", then the new variable newstr was assigned the desired to me the value is acceptable "OAK" , how to fix one word I know String strnew = str.replace("LOG", "OAK"); but what to do if str becomes WOOD rather than LOG and it is replaced by WOOD.

Answer 1

Map<String, String> replacements = new Map.of(
  "LOG", "ДУБ",
  "WOOD", "ДЕРЕВО"
);

String strnew = replacements.entrySet()
    .stream()
    .reduce(str, (acc, e) -> acc.replace(e.getKey(), e.getValue()));
