How to convert Arrays to List

1. Arrays.asList() method makes the original array available as a list. 

Example code

public class Main{
    public static void main(String[] args) {
        String[] fruit_array = new String[]{"apple","banana","mango"};
        List<String> fruit_list = Arrays.asList(fruit_array);

        //returned List is fixed size
        fruit_list.add("melon"); //Error
        fruit_list.remove(0); //Error

        fruit_list.set(1,"kiwi");
        System.out.println(fruit_list); //[apple, kiwi, mango]
    }
}

2. Using List Constructor enables some kind of operations to change the List.

Example code

public class Main{
    public static void main(String[] args) {
        String[] fruit_array = new String[]{"apple","banana","mango"};
        //Constructor
        List<String> fruit_list = new ArrayList<>(Arrays.asList(fruit_array));

        //you can do every operations on the List
        fruit_list.add("melon");
        fruit_list.remove(0);

        fruit_list.set(1,"kiwi");
        System.out.println(fruit_list); //[banana, kiwi, melon]
    }
}

3. Collection API

Example code I

public class Main{
    public static void main(String[] args) {
        String[] fruit_array = new String[]{"apple","banana","mango"};

        List<String> fruit_list = new ArrayList<>(fruit_array.length);
        Collections.addAll(fruit_list,fruit_array);

        System.out.println(fruit_list); //[apple, banana, mango]
    }
}

Example code II

public class Main{
    public static void main(String[] args) {
        String[] fruit_array = new String[]{"apple","banana","mango"};

        List<String> fruit_list = new ArrayList<>(Arrays.asList(fruit_array));
        String[] another_array = new String[]{"add1","add2"};
        Collections.addAll(fruit_list,another_array);

        System.out.println(fruit_list); //[apple, banana, mango, add1, add2]
    }
}
