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
