Given a list of integers and we have to access/retrieve element/object from given index from the list in Java.

To get the element from given index - we use List.get() method, it is a library method of the List, which returns object/element from given index.

Syntax:

    List.get(index);

Program:

import java.util.*;
public class ListExample {
	public static void main (String[] args) 
	{
		// creating a list of integers
		List<Integer> int_list = new ArrayList<Integer> ();

		//adding some of the elements
		int_list.add (10);
		int_list.add (20);
		int_list.add (30);
		int_list.add (40);
		int_list.add (50);

		//printing the empty list 
		System.out.println ("Element at " + 0 + " index = " + int_list.get (0)) ;
		System.out.println ("Element at " + 1 + " index = " + int_list.get (1)) ;
		System.out.println ("Element at " + 2 + " index = " + int_list.get (2)) ;
		System.out.println ("Element at " + 3 + " index = " + int_list.get (3)) ;
		System.out.println ("Element at " + 4 + " index = " + int_list.get (4)) ;
	}
};

Output

Element at 0 index = 10
Element at 1 index = 20
Element at 2 index = 30
Element at 3 index = 40
Element at 4 index = 50
