Question
Difference between ArrayList and vector.
Answers
- ArrayList is not thread-safe whereas Vector is thread-safe.
- In Vector class each method is surrounded with a synchronized block and thus making Vector class thread-safe.
- Both the ArrayList and Vector hold onto their contents using an Array.
- When an element is inserted into an ArrayList or a Vector, the object will need to expand its internal array if it runs out of room.
- A Vector defaults to doubling the size of its array, while the ArrayList increases its array size by 50 percent.   Your Comment
