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

// 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

// 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
