Vector

Convert Vector to Object array example

With this example we are going to demonstrate how to convert a Vector to an Object array. In order to convert a Vector to Object array we need to fill the array with all the elements in the vector in the correct order. In short, to convert a Vector to an object array you should:

  • Create a new Vector.
  • Populate the vector with elements, with add(E e) API method of Vector.
  • Invoke toArray() API method of Vector. The method returns a new Object array that contains all the elements in the vector in correct order.

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

package com.javacodegeeks.snippets.core;
 
import java.util.Vector;
 
public class ConvertVectorToObjectArray {
 
  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");
 
    // toArray() returns an array containing all of the elements in this vector in the correct order
    Object[] objArray = vector.toArray();
 
    System.out.println("Elements in Array :");
    for(int i=0; i < objArray.length ; i++)

System.out.println(objArray[i]);

  }
}

Output:

Elements in Array :
element_1
element_2
element_3
element_4
element_5

 
This was an example of how to convert a Vector to an Object array in Java.
