Lists are mutable and can change, while tuples are immutable and cannot be altered after creation.

• Mutability: Lists can be modified (e.g., list.append(1)), while tuples cannot (e.g., tuple[0] = 1 raises an error).

• Syntax: Lists use square brackets (e.g., myList = [1, 2, 3]), while tuples use parentheses (e.g., myTuple = (1, 2, 3)).

• Performance: Tuples are generally faster than lists due to their immutability, making...read more

Arrays are fixed-size, homogeneous collections; lists are dynamic, heterogeneous collections with flexible sizes.

• Arrays have a fixed size, e.g., `String[] colors = new String[5];`.

• Lists can grow or shrink dynamically, e.g., `List<String> colors = new ArrayList<>();`.

• Arrays store elements of the same type, while lists can store different types (in some languages).

• Accessing elements in arrays is faster d...read more
