To check prime numbers, we declare a function isPrime() that will return 1, if number is prime and return 0 if number is not prime. Then, in main() function – we are using a loop with 0 to len-1 (total number of array elements) and calling isPrime() by passing array elements on...

Find the first number greater thanpin the list that is not marked. If there was no such number, stop. Otherwise, letpnow equal this number (which is the next prime), and repeat from step 3. When the algorithm terminates, all the numbers in the list that are not marked are prime. ...

Java Example to print alternate prime numbers In the following example we have two user defined methods:checkPrime()andprintAltPrime(). ThecheckPrime()method checks whether the number passed as an argument is prime or not, if the number is prime, this method returns 1 else it returns false...
