Vector size example
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.
