The number which is only divisible by itself and 1 is known asprime number, for example 7 is a prime number because it is only divisible by itself and 1. This program takes the number (entered by user) and then checks whether the input number is prime or not. The program then displays...
IntStream.rangeClosed(3, (int) Math.sqrt(number)) .filter(n -> n %2!=0) .noneMatch(n -> (number % n ==0)); } 2. Program to find first N primes Given program uses Java 8 stream apis to find first N prime numbers in series. In this program, user is asked an input where...
