Good morning guys.
Following the Java course, I had to do an exercise to check if a number is prime or not. I wrote the following code. I used a scanner because I want the user to enter a number and then we analyse it and return whether it’s prime or not. I can’t get it to work. I’m using NetBeans and when I compile the file it gives me no error but it still doesn’t work.
Any help would be appreciated. Thanks in advance. The error I get is this one:
Error: Could not find or load main class PrimeDirective
package primedirective;
import java.util.Scanner;
public class PrimeDirective {
public boolean isPrime(int number){
Scanner sc = new Scanner(System.in);
System.out.println("Give me a number");
int a = sc.nextInt();
System.out.println("The number given by the user is " + a);
if (a / 1 !=0 && a / a !=0){
System.out.print("It's a prime number");
} else {
System.out.println("It's not a prime number");
}
return false;
}
public static void main(String[] args) {}
}
