Java Vector clone() Method

The clone() method of Java Vector class is used to get a clone of the vector which is in use.

Syntax:

Following is the declaration of clone() method:

Parameter:

This method does not accept any parameter.

Returns:

This method returns a clone of the vector which is in use.

Exceptions:

Compatibility Version:

Java 1.2 and above

Example 1:

  import java.util.Vector;  public class VectorCloneExample1 {    public static void main(String arg[]) {  //Create an empty vector object  Vector<String> vc = new Vector<String>();              //Adding elements to the vector              vc.add(“Tiger”);              vc.add(“Deer”);              vc.add(“Dog”);              vc.add(“Camel”);              System.out.println(“Original vector: “+vc);                    System.out.println(“Cloned vector: “+vc.clone());              }  }  

Test it Now

Output:

Original vector: [Tiger, Deer, Dog, Camel]  Cloned vector: [Tiger, Deer, Dog, Camel]

Example 2:

  import java.util.Vector;  public class VectorCloneExample2 {    public static void main(String arg[]) {  //Create an empty Vector vec with an initial capacity of 4              Vector<Integer> vc = new Vector<Integer>(4);        Vector<Integer> vecclone = new Vector<Integer>(4);        //Add elements in the vector        vc.add(4);        vc.add(3);        vc.add(2);        vc.add(1);        //Print all the elements available in vector        System.out.println(“Elements in vector are: “);               for (Integer num : vc) {                    System.out.println(“Number= ” +num);        }                 //clone the vector vec        vecclone = (Vector) vc.clone();        //Print all the elements available in vecclone        System.out.println(“Elements in vecclone vector are: “);                     for (Integer num : vecclone) {                    System.out.println(“Number = ” + num);        }  }              }  

Test it Now

Output:

Elements in vector are:   Number = 4  Number = 3  Number = 2  Number = 1  Elements in vecclone vector are:   Number = 4  Number = 3  Number = 2  Number = 1
