Java Vector lastElement() Method

The lastElement() method of Java Vector class is used to get the last component of the vector.

Syntax

Following is the declaration of lastElement() method:

Parameter

This method does not accept any parameter.

Return

The lastElement() method returns the last element of the vector i.e. the component at index size()-1.

Exceptions

NoSuchElementException– This method has thrown an exception if the vector is empty.

Compatibility Version

Java 1.2 and above

Example 1

  //Program to illustrate the lastElement() method  import java.util.*;  public class VectorLastElementExample1 {    public static void main(String arg[]) {  //Create an empty vector           Vector<String> vec = new Vector<>(4);         //Add elements in the vector              vec.add(“Java”);        vec.add(“JavaScript”);        vec.add(“Android”);        vec.add(“Python”);              //Obtain the last element of this vector  System.out.println(“The last element of a vector is: ” +vec.lastElement());        }              }  

Test it Now

Output:

The last element of a vector is: Python

Example 2

  //Program to illustrate the lastElement() method  import java.util.*;  public class VectorLastElementExample2 {    public static void main(String arg[]) {  //Create an empty vector  Vector<Integer> vectorObject = new Vector<Integer>(4);  //Add elements to the vector  vectorObject.add(11);  vectorObject.add(22);  vectorObject.add(33);  vectorObject.add(44);  //Displaying the vector list  System.out.println(“Element of a vector is: ” +vectorObject);  //Obtain the last element of this vector  System.out.println(“The last element of a vector is: ” +vectorObject.lastElement());        }              }  

Test it Now

Output:

Element of a vector is: [11, 22, 33, 44]  The last element of a vector is: 44

Example 3

  //Program to illustrate the lastElement() method  import java.util.*;  public class VectorLastElementExample3 {    public static void main(String arg[]) {      //Create an empty vector      Vector<Integer> vecObj = new Vector<Integer>(4);      //Add elements to the vector      vecObj.add(101);      vecObj.add(202);      vecObj.add(303);      vecObj.add(404);      //Obtain the last element of this vector      System.out.println(“Last element of vector is: ” +vecObj.lastElement());      //Use clear() method to remove all element of this vector      vecObj.clear();      //Again obtain the last element of this vector after clear method      System.out.println(“The last element of a vector is: ” +vecObj.lastElement());      }              }  

Test it Now

Output:

The last element of a vector is: 404  Exception in thread "main" java.util.NoSuchElementException  at java.base/java.util.Vector.lastElement(Vector.java:525)  at myPackage.VectorLastElementExample3.main(VectorLastElementExample3.java:17)
