Java provides Arrays class in java.util package. Arrays class has a

method asList() that accepts an Array as input and returns a List as

output.

public static List asList(T... a)

String[] myArray = {"George" , "Jack" , "Ryan"};

List myList = Arrays.asList(myArray);

public class Tester {
   public static void main(String args[]) {
      String[] array = {"a", "b", "c", "d", "e"};

      //Method 1
      List<String> list = Arrays.asList(array);          
      System.out.println(list);

      //Method 2
      List<String> list1 = new ArrayList<String>();
      Collections.addAll(list1, array);
      System.out.println(list1);

      //Method 3
      List<String> list2 = new ArrayList<String>();
      for(String text:array) {
         list2.add(text);
      }
      System.out.println(list2);
   }  
}
