Consider the following method:
public void printPrimeNumbers(int n) {
for (int i = 2; i <= n; i++) {
boolean isPrime = true;
for (int j = 2; j <= Math.sqrt(i); j++) {
if (i % j == 0) {
isPrime = false;
break;
}
}
if (isPrime) {
System.out.print(i + " ");
}
}
}
Assume that the method printPrimeNumbers(20) appears in a method in the same class. What is printed as a result of the method call?
