printing out prime numbers from array

Question

I\'d like to print out all prime numbers from an array with method. I can do it with one int but don\'t know how to return certain numbers from array. Thanks for help!

Answer 1

I would suggest you separate this into two methods:

• One method to determine whether a single number is prime
• One method to iterate through an array, call the first method with each number, and print out the values for which the method returns true.

That separates out the two concerns neatly. If you're stuck on exactly how to do this, please give details of which bit you find hard. (I'm assuming this is homework, which is why I haven't just included the code.)
