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);
}
}
