What are the differences between arrays and lists in Java?

What are the differences between arrays and lists in Java?

In Java, arrays are fixed in size and can hold elements of the same type, while lists (like ArrayList) are dynamic and can grow or shrink.

Can you give me an example of when to use an array instead of a list?

Sure! Use an array when you know the number of elements in advance and need fast access, like storing the days of the week.

What about performance? Are there any differences?

Yes, arrays have better performance for accessing elements due to their fixed size, while lists have overhead for dynamic resizing.

Are there any limitations to using arrays?

Yes, arrays cannot change size once created, and they can only hold elements of a single type.

What about multi-dimensional arrays?

Multi-dimensional arrays are arrays of arrays, allowing you to create matrices or tables, but they also have fixed sizes.
