Can you please use loop to solve this question and add comment on each line please? Thank you.

2. Write down a program in Java, which accepts two string inputs (string1 and string2) from the user. If the second string (string2) is present in first string (string1) (1.e., if the second string is a substring of first string), find out the number of times this string appears in the first string. Print the output saying " occurs 'n' times in " and print its last occurrence index. If second string (string2) is not a substring of first string (string1), then print " Not present in " CSE114: Introduction to Object Oriented Programming Summer 2020 Example: Enter first string: "Roger Federer" Enter second string: "er" Output: "er" occurs 3 times in "Roger Federer". Last occurrence is 11. Enter first string: "Roger Federer" Enter second string: "kl" Output: "kl" Not present in "Roger Federer"
