AbstractList get() method in Java with Examples

Last Updated : 26 Nov, 2018

The get() method of java.util.AbstractList class is used to return the element at the specified position in this list.

Syntax:

public abstract E get(int index)

Parameters: This method takes index of the element as a parameter, the element at which is to be returned.

Returns Value: This method returns the element at the specified position in this list.

Exception: This method throws IndexOutOfBoundsException if the index is out of range (index = size()).

Below are the examples to illustrate the get() method.

Example 1:

   // Java program to demonstrate 
// get() method 
// for Integer value 
  
import java.util.*; 
  
public class GFG1 { 
    public static void main(String[] argv) 
        throws Exception 
    { 
  
        try { 
  
            // Creating object of AbstractList<Integer> 
            AbstractList<Integer> 
                arrlist1 = new ArrayList<Integer>(); 
  
            // Populating arrlist1 
            arrlist1.add(10); 
            arrlist1.add(20); 
            arrlist1.add(30); 
            arrlist1.add(40); 
            arrlist1.add(50); 
  
            // print arrlist1 
            System.out.println("ArrayListlist : "
                               + arrlist1); 
  
            // getting the value at the index 3 
            // using get() method 
            int value = arrlist1.get(3); 
  
            // print the value 
            System.out.println("Element at index 3 : "
                               + value); 
        } 
  
        catch (IndexOutOfBoundsException e) { 
            System.out.println("Exception thrown : " + e); 
        } 
    } 
} 
 
  

Output:

  ArrayListlist : [10, 20, 30, 40, 50]  Element at index 3 : 40

Example 2:

   // Java program to demonstrate 
// get() method 
// for IndexOutOfBoundsException 
  
import java.util.*; 
  
public class GFG1 { 
    public static void main(String[] argv) 
        throws Exception 
    { 
        try { 
  
            // Creating object of AbstractList<Integer> 
            AbstractList<Integer> 
                arrlist1 = new ArrayList<Integer>(); 
  
            // Populating arrlist1 
            arrlist1.add(10); 
            arrlist1.add(20); 
            arrlist1.add(30); 
            arrlist1.add(40); 
            arrlist1.add(50); 
  
            // print arrlist1 
            System.out.println("ArrayListlist : "
                               + arrlist1); 
  
            // getting the value at the index 7 
            // using get() method 
            System.out.println("\nTrying to get "
                               + "the element from out"
                               + " of range index "); 
            int value = arrlist1.get(7); 
  
            // print the value 
            System.out.println("Element at index 7 : "
                               + value); 
        } 
  
        catch (IndexOutOfBoundsException e) { 
            System.out.println("Exception thrown : " + e); 
        } 
    } 
} 
 
  

Output:

  ArrayListlist : [10, 20, 30, 40, 50]    Trying to get the element from out of range index   Exception thrown : java.lang.IndexOutOfBoundsException: Index: 7, Size: 5
