Difference ArrayList Vector
Answer: Below are differences:
| ArrayList | Vector |
| ArrayList is not synchronized (Not thread safe) | Vector is synchronized (Thread safe) |
| ArrayList does not contains legacy methods | Vector class contains several legacy methods those are not part of Collections |
| Data growth: If internal array out of space then its increases size by 50 percent | Data growth: If internal array out of space then its size increases double the size of array |
Java example:
package com.javahonk.arraylistvector; import java.util.ArrayList; import java.util.List; import java.util.Vector; public class ArrayListVector { public static void main(String[] args) { Vector<String> vector = new Vector<String>(); vector.add("Java"); vector.add("Honk"); vector.add("Test"); vector.add(null); vector.add(null); System.out.println("Vector example\n"); for (String string : vector) { System.out.println(string); } System.out.println("\nArrayList example\n"); List<String> list = new ArrayList<String>(); list.add("Java"); list.add("Honk"); list.add("Test"); list.add(null); list.add(null); for (String string : list) { System.out.println(string); } } }
Output:
That’s it Difference ArrayList Vector
