indexOf() returns the index of the first occurrence of the specified character within the current String object. The first occurrence of 'm' is at index 0, thus 0 is printed first.
lastIndexOf() returns the index of the last occurrence of the specified character within the String object. The last occurrence of 'm' is at index 8, thus 8 is printed next.
