Java Vector lastElement() Method
Description
The Java Vector lastElement() method is used to return the last component of the vector.
Declaration
Following is the declaration for java.util.Vector.lastElement() method
public E lastElement()
Parameters
NA
Return Value
The method call returns the last component of the vector, i.e., the component at index size() - 1.
Exception
NoSuchElementException − This exception is thrown if this vector is empty
Getting Last Element of a Vector of Integer Example
The following example shows the usage of Java Vector lastElement() method to get an element at last position in this vector. We're creating a vector of Integer and added few elements to it using add() method. Then we've printed the element at last index using lastElement() method.
package com.tutorialspoint; import java.util.Vector; public class VectorDemo { public static void main(String[] args) { // create an empty Vector vec with an initial capacity of 4 Vector<Integer> vec = new Vector<>(4); // use add() method to add elements in the vector vec.add(4); vec.add(3); vec.add(2); vec.add(1); // let us print the last element in the vector System.out.println("Last element: "+vec.lastElement()); } }
Output
Let us compile and run the above program, this will produce the following result.
Last element: 1
Getting Last Element of a Vector of String Example
The following example shows the usage of Java Vector lastElement() method to get last element in this vector. We're creating a vector of String and added few elements to it using add() method. Then we've printed the last element using lastElement() method.
package com.tutorialspoint; import java.util.Vector; public class VectorDemo { public static void main(String[] args) { // create an empty Vector vec with an initial capacity of 4 Vector<String> vec = new Vector<>(4); // use add() method to add elements in the vector vec.add("D"); vec.add("C"); vec.add("B"); vec.add("A"); // let us print the last element in the vector System.out.println("Last element: "+vec.lastElement()); } }
Output
Let us compile and run the above program, this will produce the following result.
Last element: A
Getting Last Element of a Vector of Object Example
The following example shows the usage of Java Vector lastElement() method to get last element in this vector. We're creating a vector of Student and added few elements to it using add() method. Then we've printed the last element using lastElement() method.
package com.tutorialspoint; import java.util.Vector; public class VectorDemo { public static void main(String[] args) { // create an empty Vector vec with an initial capacity of 4 Vector<Student> vec = new Vector<>(4); // use add() method to add elements in the vector vec.add(new Student(1, "Julie")); vec.add(new Student(2, "Robert")); vec.add(new Student(3, "Adam")); vec.add(new Student(4, "Jane")); // let us print the last element in the vector System.out.println("Last element: "+vec.lastElement()); } } class Student { int rollNo; String name; Student(int rollNo, String name){ this.rollNo = rollNo; this.name = name; } @Override public String toString() { return "[ " + this.rollNo + ", " + this.name + " ]"; } @Override public boolean equals(Object obj) { Student s = (Student)obj; return this.rollNo == s.rollNo && this.name.equalsIgnoreCase(s.name); } }
Output
Let us compile and run the above program, this will produce the following result.
Last element: [ 4, Jane ]
