The вЂњenвЂќ is an enumeration, which helps to iterate through a vector. Therefore, when passing вЂњorangeвЂќ to the remove method, that specific element is removed from the vector. Similarly, the remove method helps to remove an element from the vector. The add method helps to insert new elements into the vector. In the above program, вЂњvecвЂќ is an object of Vector that can store strings. The programmer can use them in his program. Moreover, there are predefined methods available in ArrayList class. ArrayList maintains the element inserted order. Therefore, it is a flexible data structure. In other words, the programmer can add or remove elements dynamically. Using an ArrayList, it is possible to change the array size dynamically. Therefore, the programmer cannot add more elements than the defined array size. This ArrayList class further implements the List interface. вЂ“ Comparison of Key Differences Key TermsДЄrrayList is a data structure that is implemented using the ArrayListClass. What is the Difference Between ArrayList and Vector

On the other hand, vector is synchronized and contains many legacy methods. ArrayList is non-synchronized, which makes an ArrayList performs better than a Vector. Two such collections are ArrayList and Vector. Programming languages such as Java supports collections, which allows storing multiple objects as a single unit. The main difference between ArrayList and Vector is that the ArrayList is non-synchronized and allows multiple threads to work on an ArrayList at the same time while the Vector is synchronized and avoids multiple threads working on a vector at the same time.
