Advantages of Java Arrays
Efficient Access: Accessing an element by its index is fast and has constant time complexity, O(1).
Memory Management: Arrays have fixed size, which makes memory management straightforward and predictable.
Data Organization: Arrays help organize data in a structured manner, making it easier to manage related elements.

Disadvantages of Java Arrays
Fixed Size: Once an array is created, its size cannot be changed, which can lead to memory waste if the size is overestimated or insufficient storage if underestimated.
Type Homogeneity: Arrays can only store elements of the same data type, which may require additional handling for mixed types of data.
Insertion and Deletion: Inserting or deleting elements, especially in the middle of an array, can be costly as it may require shifting elements.
