Vector in java collection

 Program of vector in java collection framework

Vector class implements a growable array of object means vector can increase their size.

Program//code

package com.vector;


import java.util.Vector;


//The Vector class implements a growable array of objects.

public class Vector1 {

public static void main(String[] args) {

//creating vector

Vector<Integer> v = new Vector<>();

//add element

v.addElement(34);

v.addElement(33);

v.addElement(31);

System.out.println(v);

//insert element at index 1

v.insertElementAt(12, 2);

System.out.println("adding 12 at index 2:"+v);

//remove element

v.removeElementAt(1);

System.out.println("Remove element from index 1:"+v);

//print all with for loop

for(int j : v) {

System.out.print(j+" ");

}


}

}





//Output

[34, 33, 31]

adding 12 at index 2:[34, 33, 12, 31]

Remove element from index 1:[34, 12, 31]

34 12 31
