Vector

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.
