Program: How to copy or clone a vector?


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]

Interface and its usage
Interface is similar to a class which may contain method's signature only but not bodies and it is a formal set of method and constant declarations that must be defined by the class that implements it. Interfaces are useful for declaring methods that one or more classes are expected to implement, capturing similarities between unrelated classes without forcing a class relationship and determining an object's programming interface without revealing the actual body of the class.
