Android Set <String> to array

Question

I am new to android programming. I have saved my data insharedPreference and get the data back and store as following

        Set <String> set = sharedPref.getStringSet(dayName, null);

This Set <String> set got 3 array stored in a row arrayOne, arrayTwo, arrayThree with a TAG. Is there any way to convert it into array and save individually.

Thanks for the help.

try this example

Set<String> set = new HashSet<String>();
set.add("object 1");
set.add("object 2");
set.add("object 3");
set.add("object 4");

String[] array = null;

array = set.toArray(new String[set.size()]);

for(String item:array){
    System.out.println(item);
}

You can convert Set<String> into Array of String as follows...

Set <String> set = sharedPref.getStringSet(dayName, null);
List<String> list = new ArrayList<String>(set);
String[] objects = list.toArray();
