How to copy vector to array

package com.java2novice.vector;

import java.util.Vector;

public class MyVectorArrayCopy

{

public static void main(String a[])

{

        Vector vct = new Vector();

        vct.add("First");

        vct.add("Second");

        vct.add("Third");

        vct.add("Random");

        System.out.println("Actual vector:"+vct);

        String[] copyArr = new String[vct.size()];

        vct.copyInto(copyArr);

        System.out.println("Copied Array content:");

        for(String str:copyArr)

       {

            System.out.println(str);

        }

    }

}

How to get sub list from vector

package com.java2novice.vector;

import java.util.List;

import java.util.Vector;

public class MyVectorSubRange

{

public static void main(String a[])

{

        Vector vct = new Vector();

        vct.add("First");

        vct.add("Second");

        vct.add("Third");

        vct.add("Random");

        vct.add("Click");

        System.out.println("Actual vector:"+vct);

        List list = vct.subList(2, 4);

        System.out.println("Sub List: "+list);

    }

}

Basic Linked List Operations

package com.java2novice.linkedlist;

import java.util.LinkedList;

public class MyBasicOperations

{

public static void main(String a[])

{

        LinkedList ll = new LinkedList();

        ll.add("Orange");

        ll.add("Apple");

        ll.add("Grape");

        ll.add("Banana");

        System.out.println(ll);

        System.out.println("Size of the linked list: "+ll.size());

        System.out.println("Is LinkedList empty? "+ll.isEmpty());

        System.out.println("Does LinkedList contains 'Grape'? "+ll.contains("Grape"));

    }

}

How to read all elements in Linked List by using iterator

package com.java2novice.linkedlist;

import java.util.Iterator;

import java.util.LinkedList;

public class MyLinkedListIterate

{

 public static void main(String a[])

{

        LinkedList arrl = new LinkedList();

        arrl.add("First");

        arrl.add("Second");

        arrl.add("Third");

        arrl.add("Random");

        Iterator itr = arrl.iterator();

        while(itr.hasNext())

         {

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

        }

    }

}

How to add all elements of a list to Linked List

package com.java2novice.linkedlist;

import java.util.ArrayList;

import java.util.LinkedList;

import java.util.List;

public class MyLinkedListNewCollection

{

public static void main(String a[])

{

        LinkedList arrl = new LinkedList();

        arrl.add("First");

        arrl.add("Second");

        arrl.add("Third");

        arrl.add("Random");

        System.out.println("Actual LinkedList:"+arrl);

        List list = new ArrayList();

        list.add("one");

        list.add("two");

        arrl.addAll(list);

        System.out.println("After Copy: "+arrl);

    }
