To Retrieve a Particular Object From an ArrayList

In this section you will learn to retrieve an ArrayList object (that contains multiple elements) using the get() method. Here is an example that provides the usage of the get() method in more detail.

Create a class "Get" with an ArrayList .Populate it with the integer objects. Now retrieve an object( that is contained in the arraylist) using the get() method.

Here is the Code of the Example :Get.java:


import java.util.*;

public class Get{

    public static void main(String argv[]){

    List v = new ArrayList
    ();

    v.addAll(Arrays.asList(new Integer[]{1,2,3,4}));

     

 //cast the int value to an Integer object

Integer iw =(Integer)v.get(2); System.out.println(iw); } }

Here is the Output of the Example :

C:\roseindia>javac get.java

C:\roseindia>java get
