如何使数组列表的get方法更简单？[副本]

Question

import java.util.*;

public class ChristmasParty
{
    private Scanner input = new Scanner(System.in);

    public static void main(String[] args)
    {
        ChristmasParty cp = new ChristmasParty();
        cp.run();
    }

    public void run()
    {
        menu();
        addName();
    }

    public void menu()
    {
        System.out.println("Welcome to the guests lists program");
        System.out.println("Enter a name or enter X to quit");
    }

    public void addName()
    {
        String nameAdded = "";
        ArrayList<String> guestsLists = new ArrayList<String>();
        do
        {
            System.out.print("Enter a name: ");
            nameAdded = input.nextLine();

            guestsLists.add(nameAdded);
            System.out.println("-----------------------------------------------");
            System.out.println(nameAdded + " has been added to the guests list.");

        }while(!nameAdded.equals("X"));
        System.out.println("Guests lists:");
        System.out.println("========================");
        System.out.println(guestsLists.get(0));
        System.out.println(guestsLists.get(1));
        System.out.println(guestsLists.get(2));
        System.out.println(guestsLists.get(3));
        System.out.println(guestsLists.get(4));
        System.out.println(guestsLists.get(5));
        System.out.println(guestsLists.get(6));
        System.out.println(guestsLists.get(7));
        System.out.println(guestsLists.get(8));
        System.out.println(guestsLists.get(9));
        System.out.println(guestsLists.get(10));
        System.out.println(guestsLists.get(11));
        System.out.println(guestsLists.get(12));
        System.out.println(guestsLists.get(13));
        System.out.println(guestsLists.get(14));
        System.out.println(guestsLists.get(15));
    }
}  

Answer 1

放入此代码：

}while(!nameAdded.equals("X"));

System.out.println("Guests lists:");
System.out.println("========================");

for(int i = 0; i < guestsLists.size(); i++)
{
    System.out.println(guestsLists.get(i));
}

或

for(String s : guestsLists)
{
    System.out.println(s);
}

然后删除所有sysouts
