This week we will further understand how to use arrays to implement an ADT bag in Java. Define array and give a simple code example demonstrating your understanding. How can you determine if you would need to utilize a fixed$-$size array or a dynamically$-$resizable array?

In your answer, specifically think of and give a real$-$life scenario where:

The array data structure can be used

The array list data structure can be used
