String index out of range with replace all

Question

How can I replace mapDir surrounded by <> to a certain string?

  String mapDir = "D:\\mapping\\specialists\\ts_gpc\\";
  String test = "foo: <mapDir> -bar";
  println(test.replaceAll("<mapDir>", mapDir));

The above gives me a StringIndexOutOfBoundsException.

This code below for me, but I think pure java has to work as well.

static String replaceWord(String original, String find, String replacement) {
    int i = original.indexOf(find);
    if (i < 0) {
        return original;  // return original if 'find' is not in it.
    }

    String partBefore = original.substring(0, i);
    String partAfter  = original.substring(i + find.length());

    return partBefore + replacement + partAfter;
}

You dont need replaceAll method as you are not using regex. Instead you could work with replace api like below:

String mapDir = "D:\\mapping\\specialists\\ts_gpc\\";
String test = "foo: <mapDir> -bar";
System.out.println(test.replace("<mapDir>", mapDir));
