But this logic can be further optimized to only loop through the square root of the number instead of the number itself, as shown in the below example. This will make the Java program fast for checking large prime numbers. Here is a list of all prime numbers between 1 and 100: ...

To check prime numbers, we declare a functionisPrime()that will return 1, if number is prime and return 0 if number is not prime. Then, inmain()function – we are using a loop with 0 tolen-1(total number of array elements) and callingisPrime()by passing array elements one by one ...
