Answer 1

class ReplaceLastOccurrenceOfSubstringInAString_Java {
    public static String replaceLastOccurrence(String s, String subs, String replace) {
        int pos = s.lastIndexOf(subs);

        if (pos == -1)
            return s;

        s = s.substring(0, pos) + replace + s.substring(pos + subs.length());
