Remove all elements from Vector example

With this example we are going to demonstrate how to remove all elements from a Vector. We are using clear() API method of Vector. In short, to remove all elements from a Vector you should:

  • Create a new Vector.
  • Populate the vector with elements, with add(E e) API method of Vector.
  • Invoke clear() API method of Vector. The method removes all of the elements from this Vector. The Vector will be empty after this call returns.

Let’s take a look at the code snippet that follows:

package com.javacodegeeks.snippets.core;
import java.util.Vector;
public class ClearVectorExample {
  public static void main(String[] args) {
    // Create a Vector and populate it with elements
    Vector vector = new Vector();
    System.out.println("Vector size before removing elements : " + vector.size());

    // Vector clear() operation removes all elements

    System.out.println("Vector size after removing elements : " + vector.size());


Vector size before removing elements : 3
Vector size after removing elements : 0

This was an example of how to remove all elements from a Vector in Java.
