In this example we shall show you how to get the Vector size, that is the number of elements that a Vector contains. To get the Vector size one should perform the following steps:

Create a new Vector.
Populate the vector with elements, with add(E e) API method of Vector.
Get the Vector size, using size() API method of Vector. It returns the int number of components in this vector,

as described in the code snippet below.

package com.javacodegeeks.snippets.core;
 
import java.util.Vector;
 
public class VectorSizeExample {
 
  public static void main(String[] args) {

    // Create a Vector and populate it with elements
    Vector vector = new Vector();
    vector.add("element_1");
    vector.add("element_2");
    vector.add("element_3");
    vector.add("element_4");
    vector.add("element_5");
 
    int elementsCount = vector.size();
 
    System.out.println("Elements in Vector :");
    for(int i=0; i < elementsCount; i++)

System.out.println(vector.get(i));
 
  }
}

Output:

Elements in Vector :
element_1
element_2
element_3
element_4
element_5

This was an example of how to get the Vector size in Java.

Thank you!
