VectorDemo.java

import java.util.Random;

import java.util.Vector;

public class VectorDemo {

public static void main(String[] args) {

//Creating a random Class object

Random r = new Random();

Vector<Object> vector=new Vector<Object>();

int primitiveInt=241;

Integer wrapperInt=new Integer(1234);

String str="Kane";

vector.add(primitiveInt);

vector.add(wrapperInt);

vector.add(str);

vector.add(2,new Integer(2318));

System.out.println("The Elements of vector:"+vector);

System.out.println("The size of vector is :"+vector.size());

System.out.println("The Element at position 2 is :"+vector.elementAt(2));

System.out.println("The first Elementof vector is :"+vector.firstElement());

System.out.println("The first Elementof vector is :"+vector.firstElement());

System.out.println("The last Elementof vector is :"+vector.lastElement());

//Inserting 3 random Numbers Between 10 and 30 into the vector

for(int i=0;i<3;i++)

{

vector.add(r.nextInt((20) + 1) + 10);

}

System.out.println("The Elements of vector:"+vector);

System.out.println("The size of vector is :"+vector.size());

//Removing all elements in the odd index

for(int i=1;i<vector.size();i++)

{

vector.removeElementAt(i);

}

//After Removing the odd indexed elements in the vector

System.out.println("The Elements of vector:"+vector);

System.out.println("The size of vector is :"+vector.size());

}

}
