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.
