[Solved] Random Number generator in a range and then print length of the sequence [duplicate]

by


Consider using a while-loop:

import java.util.Random;

class Sequence {
    public static void main(String[] args) {
        Random r = new Random();
        int count = 0;
        int num = -1;
        System.out.println("The sequence is:");
        while (num != 0) {
            num = r.nextInt(10);
            System.out.print(num + " ");
            count++;
        }
        System.out.printf("%nThe length of the sequence is: %d%n", count);
    }
}

Example Output:

The sequence is:
3 9 3 9 4 0
The length of the sequence is: 6

Alternatively if you need to store the sequence in a collection:

import java.util.ArrayList;
import java.util.List;
import java.util.Random;

class Sequence {
    public static void main(String[] args) {
        Random r = new Random();
        List<Integer> result = new ArrayList<>();
        int num = -1;
        while (num != 0) {
            num = r.nextInt(10);
            result.add(num);
        }
        System.out.printf("The sequence is: %s%n", result);
        System.out.printf("The length of the sequence is: %d%n", result.size());
    }
}
