how to change string array to array. String[] to ArrayList<string> format conversion [duplicate]

Question

How do I convert String Array to Array List:

String[] to ArrayList<String>

Answer 1

Try this:

String [] strings = new String [] {"stack", "overflow" };
List<String> stringList = new ArrayList<String>(Arrays.asList(strings)); 

Answer 2

Try this one

private ArrayList<String> list = new ArrayList<String>();
list.clear();

for(int i=0;i<StringArray.length;i++)
{
    list.add(StringArray[i]);
}

Answer 3

Try this..

String[] arr = { "40", "50", "60", "70", "80", "90", "100", };

ArrayList<String> arr_list = new ArrayList<String>();

for (int i = 0; i < arr.length; i++)
    arr_list.add(arr[i]);

or

ArrayList<String> arr_list = new ArrayList<String>(Arrays.asList(arr)); 

Answer 4

You can do

• Use the Arrays.asList() method

  List<String> list = Arrays.asList(strings);
  

• Create a new ArrayList and copy the elements of the array (not recommended)

  List<String> list = new ArrayList<String>();
  
  for (String str : strings)
  {
      list.add(str);
  }
  

Hope this helps.

Try this:

String[] words = {"ace", "boom", "crew", "dog", "eon"};  

List<String> wordList = Arrays.asList(words);  

for (String e : wordList)  
{  
    System.out.println(e);  
}
