Java – string index using replace all is out of range

How to 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 a string index out of boundary exception

The following code is for me, but I think pure Java must also work properly

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;
}

Solution

You don't need the replaceall method because you don't use regular expressions Instead, you can use the following alternative API:

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