What are the differences between Array and ArrayList in Java?
An example of an AI chatbot conversation about Java Array vs ArrayList differences.
What are the differences between Array and ArrayList in Java?
Arrays are fixed in size and can hold primitive types, while ArrayLists are resizable and can only hold objects.
Can you give me an example of when to use an Array instead of an ArrayList?
Use an Array when you know the number of elements in advance and need better performance for primitive types.
What are the performance implications of using ArrayList?
ArrayLists have overhead due to resizing and boxing/unboxing for primitives, but they offer more flexibility.
Are there any limitations to using ArrayLists?
Yes, ArrayLists cannot store primitive types directly and may lead to increased memory usage due to object wrappers.
