This unit introduces important methods and fields for working with arrays in Java. These tools simplify common operations like accessing the size of an array, converting it to a readable format, sorting it, resizing it, or filling it with specific values. These concepts are crucial for the AP exam, especially for Free Response Question #3, where you will need to use multiple of these methods to work with Arrays.
