Cash register java using a random number generator and queue structure -

im trying make simulation of random number of customers going cash register. each cash register can hold 10 customers. during each random wave customer attended maximum of 5 lines.

random rand = new random(20041995);  (int j = 0; j < 10; j++) {     int pick = rand.nextint(10);     system.out.println(pick); } 

this rng i'm using , i'm trying integrate standard queue structure adds , deletes items in list.

this might point in right direction:

public static void main(string[] args) {      random randomcustomer = new random();      list<integer> generatedcustomers = new arraylist<integer>();      //counter went 50 because each register holds 10 people      for(int counter=1; counter<=50;counter++) {         int customer = randomcustomer.nextint(20041995);             //the random generated customers added         generatedcustomers.add(customer);     }         //used sublist method once got size of array , split 5 parts     (int start =0; start < generatedcustomers.size(); start += 10) {         int end = math.min(start + 10, generatedcustomers.size());          list<integer> sublist = generatedcustomers.sublist(start, end);          system.out.println("cash register" + " " + sublist);      } } 

}

my output generated this:
