Remove all elements from Vector in Java

This example shows how to remove all elements from Vector at once. You can call the method clear() to remove all values from Vector with a single call.

import java.util.Vector; 

public class Clear_vector {

 public static void main(String[] args) {
 Vector< String>  vct = new Vector< String> (); 
 //add elements
 vct.add("un"); 
 vct.add("two"); 
 vct.add("three"); 
 vct.add("four"); 
 
 System.out.println("Before deletion:"); 
 for(String e:vct)
 System.out.println(e); 

 System.out.println("\nAfter deletion:"); 
 vct.clear(); 
 for(String e:vct)
 System.out.println(e); 
 }
}

Runtime:

Before deletion:
one
two
three
