Good day,
I have a small issue, that despite finding a couple of solutions online, I wasn't able to apply the proper outcome to my project.
This is my code:
package RandomKeyGenerator;
import java.util.Random;
import java.util.Scanner;
public class start {
public static void main(String[] args) {
GenerateKey();
}
public static void GenerateKey() {
Scanner scanner = new Scanner (System.in);
String key;
int i, k, j = 0, sub;
Random random = new Random();
char[] characters = {'A', 'B', 'C', 'D', 'E'};
System.out.println("How many keys?");
int keys = scanner.nextInt();
do{
key = "";
i = 0;
do{
k = 0;
do{
sub = random.nextInt(characters.length);
k++;
key += characters[sub];
}while (k < 4);
if (i<3) key += "-";
i++;
}while (i < 4);
System.out.println(key);
j++;
}while (j < keys);
scanner.close();
}
}
This should generate me some strings, but I receive this error, indicating some paths are not present:
Error: Could not find or load main class RandomKeyGenerator.start
Caused by: java.lang.ClassNotFoundException: RandomKeyGenerator.start
Looking forward for the solution.
I figured it out. The code itself is correct, but the issue was, that I created this project in an old directory with JRE System Library [JavaSE-1.8]. After creating a completely new directory, now with JRE System Library [JavaSE-12] and again with the option "Build Automatically", I copied exactly the same .java file there and now it works fine!
Lesson learned. I hope this would be of any help to somebody.
