, and the duplicate char is stored in ArrayList. We use the Collections.sort () function to sort the characters in the ArrayList, so the same characters must be contiguous. It then loops through the elements in the TreeSet collection, looking for the first and last occurrence of the element in ArrayList, the number of occurrences = The last occurrence-the number of occurrences of the first occurrence of +1.Second, the source codeProgram 1:Operation Result:Program 2:Operation Result:Program 3: O
