Description:

Below example shows how to create exactly same object as available vector object. You can use clone() method to create similar copy of vector.


Code:
package com.java2novice.vector;

import java.util.Vector;

public class MyVectorClone {
	public static void main(String a[]){
		Vector<String> vct = new Vector<String>();
		//adding elements to the end
		vct.add("First");
		vct.add("Second");
		vct.add("Third");
		vct.add("Random");
		System.out.println("Actual vector:"+vct);
		Vector<String> copy = (Vector<String>) vct.clone();
		System.out.println("Cloned vector:"+copy);
	}
}

Output:
Actual vector:[First, Second, Third, Random]
Cloned vector:[First, Second, Third, Random]
