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
