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
