Insert an array list of objects with addAll(ArrayList) method

In this section you will learn to insert an array list of objects to another list.

Here is an example that provides the usage of the addAll(Arrayist) method in more detail.

 

Create a class "addAll" with an ArrayList . Populate it with the object using  the addAll(ArrayList) method.

 

Learn how to use the addAll method of the List interface. Example code discussed here will tell you how to do this.

Here is the Code of the Example :

 

 

 

 

AddAll.java:

import java.util.*;
public class addAll{
  public static void main(String argv[]){
  List v = new ArrayList();
  v.addAll(Arrays.asList(new Integer[]{1,2,3,4}));
  for(int i=0; i < v.size();i ++){
  Integer iw =(Integer) v.get(i);
  System.out.println(iw);
  }
  }
}

Here is the Output of the Example :
