Writing Classes in AP Computer Science A

To ensure compatibility across different programming languages, as recursion is universally supported.

To express complex problems more simply when there are clear base cases and recursive steps.

To minimize execution time, regardless of the nature of the problem being solved.

To reduce memory usage since recursion requires less storage space than iteration.

void performCriticalOperation(); // No declared exceptions for either class

void performCriticalOperation() throws Exception {} // For both classes

void performFileParsing() throws FileNotFoundException {}; void establishConnection() throws SocketException {};

void performCriticalOperation() throws IOException, NetworkFailureException {} // For both classes

set(index, element)

get(index)

Using different classes that implement a common interface and calling methods defined by that interface

3. Casting from one class type into another within a hierarchy

2. Adding elements of different but related types into a standard java.util.ArrayList

1. Answering calls with multiple parameters through method overloading
