Return Value

NA

Exception

  • NA

Example

The following example shows the usage of java.util.Vector.removeAllElements() method.

package com.tutorialspoint;

import java.util.Vector;

public class VectorDemo {
   public static void main(String[] args) {
      // create an empty Vector vec with an initial capacity of 4      
      Vector vec = new Vector(4);

      // use add() method to add elements in the vector
      vec.add(4);
      vec.add(3);
      vec.add(2);
      vec.add(1);

      // let us print all the elements available in vector
      System.out.println("Added numbers are :- "); 
      for (Integer number : vec) {         
         System.out.println("Number = " + number);
      }
      System.out.println("Size of the vector: "+vec.size());
      
      System.out.println("Removing all elements");
      // lets remove all the elements
      vec.removeAllElements();
      
      System.out.println("Now size of the vector: "+vec.size());      
   } 
}

Let us compile and run the above program, this will produce the following result.

Added numbers are :- 
Number = 4
Number = 3
Number = 2
Number = 1
Size of the vector: 4
Removing all elements
Now size of the vector: 0
