This is the third solution to check whether a given number is Armstrong number or not. This program uses the map() and reduce() methods of java streams.
-
This is the third solution to find sum of integers in a given alphanumeric string. This program uses the filter(), map() and reduce() methods of java streams.
-
This is the third solution to find sum of integers in an array list. This program uses the reduce() method of java streams.
-
This is the third solution to find the ‘nth terms’ in the fibonacci series using BigInteger data type. This program uses the Multithreads concept to find the more than one ‘nth terms’ in the fibonacci series in parallel to save the time.
-
This is the fourth solution to find the factorial from the ArrayList of big integers using Multithreads. This program uses the Multithreads concept to find the factorial of given big integers in parallel to save the time.
-
This is the fourth solution to list all the subsets or substrings of a given strings from the ArrayList of Strings, using Multithreads. This program uses the Multithreads concept, and uses the String’s class substring method for intermediate processing of all sized sub strings.
-
This is the first solution to find the missing prime numbers from any given sequence of integers. This solution uses the Lambda expression with single abstract method. The solution is finding all the missing prime numbers between every pair for consecutive numbers from the given sequence till end. The logic for prime check is the
-
This is the third solution to reverse each word in the given input sentence. This program uses the Single Abstract method, which implemented by using Lambda expression.
-
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.
-
This is the third solution to check whether the given integer number is prime or not. This solution uses the Lambda expression with single abstract method. The implementation is to check the divisibility of the given number, from 2 to till the square root of the given number.
