How to find sum of digits in an integer value
This is the second solution to find the sum of digits of an integer value[s]. This solution defines a functional interface with single abstract method with lambda expression. The internal core logic converts an integer value to String, then parse each character to digit, and sums up each digit.

How to find subsets of a given string
This is the third solution to list all the subsets or substrings of a given string. This approach uses functional interface with single abstract method implementation using lambda expression, the internal logic utilizes the String’s class substring method for intermediate processing of all sized sub strings.

How to find length of alpha numeric value or string
This is the second solution to find the length of an alpha numeric or string value, using functional interface and lambda expression without return statement. This approach uses direct String class length method.
-
How to find length of long integer value using String class
This is the second solution to find the length of a given long integer value with help of functional interface and lambda expression. The internal logic is same that is converting long to string, and apply length method.
