I have an array of string defined as follows:

string[] items = { "Item 1", "Item 2", "Item 3", "Item 4"};

Then I have a model defined as :

public class ItemModel {

        public int Id { get; set; }

        public string ItemName { get; set; }

        public bool IsItem { get; set; }
}

I have defined a list as :

var listItems = new List<ItemModel>();

I want to add the items from the array items to the list of object of listItems. I want to add the items to ItemName

This can be achieved using a very simple Linq:

listItems  = items.Select(i => new ItemModel { ItemName = i}).ToList();

Java List, List<String> list = new ArrayList<>(); list.add("element 1"); list.add("element 3"); Object[] objects = list.toArray();. Java array to list to array conversions with inbuilt features. With Java, putting contents of an Array into a new List object or adding into an existing List object can be achieved easily using a for() loop; just by going through each and every element in array and adding to List one at a time. But that is not needed.

You could either use Select as:

  var result = items.Select(i => new ItemModel {ItemName = i}).ToList()

Or:

foreach(var item in items)
{
    listItems.Add(new ItemModel{ItemName = item});
}

Adding Elements to an ArrayList, This method returns a reference to an object in the list, which is of type E . Here is our example program, where the type in the list is String . ArrayList after three  Essentially, all objects extend the Object class. This means, all classes inherit the methods of the Object class, but not all Objects inherit your .info() method. You should avoid using Object generically, when possible Object s = "pi"; Object n = 3.1415; Object p = Math.PI; All 3 objects; very different outcomes. Hope this helps!

You can try this:

    listItems = items.Select(i => new ItemModel { Id = Array.IndexOf(items, i), ItemName = i, IsItem = true }).ToList();

Use Array Lists in Java, To create an array list in Java, you declare an ArrayList variable and call the ArrayList constructor to instantiate an ArrayList<String> friends = new ArrayList​<String>();. Adding elements. You use the add method to add objects to the array list: This often overlooked method uses an accumulator to reduce all items in an array to a single value. Great for calculating totals. The returned value can be of any type (i.e. object, array, string, integer). Add up the integers in an array. const numbers = [5, 10, 15]; const total = numbers.reduce ( (accumulator, currentValue) => accumulator

Java ArrayList - ArrayList methods, sorting, traversing, Single elements can be added to an ArrayList with the add() method. into an array list — a string, double, integer, object, and enumeration. 2) Items is an Array containing Data1,Data2 <–basically a csv, 1 string split with a comma 3) I create a new psobject and splat the properties, the key is the first item from the split and the value is the second item from the split. 4) After creating the new object, I tell Powershell to add it back into the Empty array. # [email protected] ()
