}

for(int i=0;i<tickets;i++){
System.out.println("Name:");
Scanner nom=new Scanner(System.in);
String name=nom.nextLine();
BookingList.add(name);

counter--;
}
}
}

t1.reservation();
}
}
This is my code and it works perfectly.The only problem I have is i need
to check the age of each and every person whether they are above 18 and
then book the ticket for that person else cancel it.I couldnt get a better
idea ,so i put it inside "if" chking for ticket availability and now i can
get only the age of one person.i need to iterate through each person and
print their age.shld i use a "while" loop instead?
Thank you.
