Is there a way for me to randomly generate Strings from an array without duplicating one more than twice?

currently making a program that will generate a list of Strings from two different arrays, but right now all it does is repeatedly generate Strings the desired amount of times, sometimes with multiple duplicates.

    public class ListGenerator
    {
          public static void main(String[] args)
          { 
           //number generator to determine which string to print
           Random generator = new Random();
           int rand;

           //counter to determine number of printed lines
           int counter = 0;

           //coin flip to say which array the string will come from
           Random coinFlip = new Random();
           int coin;

           String[] list1;
           list1 = new String[5]
           list1[0] = "Alpha"
           list1[1] = "Beta"
           list1[2] = "Charlie"
           list1[3] = "Delta"
           list1[4] = "Echo"

           String[] list2;
           list2 = new String[5]
           list2[0] = "Apple"
           list2[0] = "Pear"
           list2[0] = "Grape"
           list2[0] = "Banana"
           list2[0] = "Orange"

           for(counter = 0; counter < 15; counter++)
           {
                coin = coinFlip.nextInt(2)+1;

                if(coin == 1)
                {
                      rand = generator.nextInt(list1.length);
                      System.out.println(list1[rand]);
                }
                else if(coin == 2)
                {
                      rand = generator.nextInt(list2.length);
                      System.out.println(list2[rand]);
                }
           }
           }
    }

Is there a way to make it so that I could generate a String like "Apple" or "Beta" no more than twice in the 15 lines generated?

Ex Desired Output:

    (1) Apple [printed first time]
    (2) Charlie [printed first time]
    (3) Pear [printed first time]
    (4) Beta [printed first time]
    (5) Apple [printed second time]
    (6) Echo [printed first time]
    (7) Banana [printed first time]
    (8) Banana [printed second time]
    (9) Echo [printed second time]
    (10) Alpha [printed first time]
    (11) Grape [printed first time]
    (12) Delta [printed first time]
    (13) Beta [printed second time]
    (14) Orange [printed first time]
    (15) Grape [printed second time]

Where 5 of those Strings were generated twice but not more than twice, but instead in my code it could generate any of those Strings 3, 4, 5, etc. times.

I know my code isn't organized the best or the most efficient I just need help on this duplication thing
