Insert all elements of other Collection to Specified Index of Java Vector 

import java.util.ArrayList;

import java.util.Vector;

public class InsertAllElementsOfOtherCollectionToVectorExample

{

 public static void main(String[] args)

{

 Vector v = new Vector();

v.add("1");

v.add("2");

v.add("3");

ArrayList arrayList = new ArrayList();

arrayList.add("4");

arrayList.add("5");

v.addAll(1,arrayList);

System.out.println("After inserting all elements of ArrayList at index 1,

Vector contains..");

for(int i=0; i

System.out.println(v.get(i));

    }

}

Iterate through elements Java Vector using Iterator

import java.util.Vector;

import java.util.Iterator;

public class IterateThroughVectorUsingIteratorExample

{

public static void main(String[] args)

{

Vector v = new Vector();

v.add("1");

v.add("2");

v.add("3");

v.add("4");

v.add("5");

Iterator itr = v.iterator();

System.out.println("Iterating through Vector elements...");

while(itr.hasNext())

System.out.println(itr.next());

   }

}

Iterate through elements Java Vector using List Iterator

import java.util.Vector;

import java.util.ListIterator;

public class IterateThroughVectorUsingListIteratorExample

{ 

public static void main(String[] args)

{

Vector v = new Vector();

v.add("1");

v.add("2");

v.add("3");

v.add("4");

v.add("5");

ListIterator itr = v.listIterator();

System.out.println("Iterating through Vector elements in forward direction...");

while(itr.hasNext())

System.out.println(itr.next());

System.out.println("Iterating through Vector elements in backward direction...");

while(itr.hasPrevious())

System.out.println(itr.previous());

   }

}

Remove all elements from Java Vector

import java.util.Vector; 

public class RemoveAllElementsOfVectorExample

{

public static void main(String[] args)

 {

Vector v = new Vector();

v.add("1");

v.add("2");

v.add("3");

System.out.println("Size of Vector before removing elements : " + v.size());

v.clear();  System.out.println("Size of Vector after removing elements : " + v.size());

   }

}

Remove an element from specified index of Java Vector

import java.util.Vector;

public class RemoveElementFromVectorByIndexExample

{   

public static void main(String[] args)

{

Vector v = new Vector();

v.add("1");

v.add("2");

v.add("3");

v.add("4");

v.add("5");

Object obj = v.remove(1);

System.out.println(obj + " is removed from Vector");

System.out.println("Vector contents after remove call...");

for(int index=0; index < v.size(); index++)

System.out.println(v.get(index));

v.removeElementAt(2);

System.out.println("Vector contents after removeElementAt call...");

for(int index=0; index < v.size(); index++)

System.out.println(v.get(index));

   }

}
