Difference b/w Vector and an ArrayList

[Raj Kumar Bindal]

Please tell me all differences b/w a Vector and an ArrayList
**Plz also tell the situations in which each one of them should be used

[William Brogden]

Questions such as this are addressed in the JavaDocs for the java.util package. No-one should try to be a Java programmer without knowing how to navigate in the JavaDocs. If you have room on your hard drive why not download and install a copy.

Your one stop for clear understanding of differences between collection framework classes

You should be aware of old java collections and new java collections classes

Hi Raj,

Please download and install the JAVA DOC. It will solve most of your doubts.

There is only one fundamental difference between the Vector and ArrayList, even though both implement from same base interface.

The Vector is synchronized, means it is thread safe. Only one thread of your application can access a vector at a time.

Where as the ArrayList is not synchronized.

As you see, ArrayList gives more performance when you want to access elements from middle of the list and insert and delete in end positions only.

Thank you.
