June 29, 2021 - The last code example demonstrates how the first ‘n’ prime numbers can be calculated where ‘n’ is any number. For instance, if the user specifies ‘n’ as 5, the first five prime numbers starting from 2 and ending at 11 would be displayed. This is because the first five numbers are 2,3, 5, 7, and 11. ... import java.util.Scanner; public class MyClass { public boolean numberIsPrime(int n) { for (int i = 2; i < n; i++) { if (n % i == 0) return false; } return true; } public static void main(String[] args) { MyClass test = new MyClass(); Scanner userInput = new Scanner(System.in); System.out.print("Enter the number of primes to be displayed: "); int num = userInput.nextInt(); int count = 0; for (int i = 2; count < num; i++) { if (test.numberIsPrime(i)) { System.out.print(i + " "); count++; } } } }

For better understanding an example is given in the next section. ... Above code snippet instantiates 2 arrays of double type names list1 and list2.
