    public static void main(String[] args) {
        System.out.println("Prime numbers:");
        int count = 1;
        for (int i=1;count<=50;i++) {
            int flag = 0;
            for (int j=1; j<=i; j++) {
                if (i%j==0) {
                    flag++;
                }
            }
            if (flag==2) {
                System.out.print(i+" ");
                count++;
            }
