Analyze this code, and identify areas where Unchecked Exceptions can be added to improve stability. Determine $57$ relevant Unchecked Exceptions and decide whether they should be handled locally or propagated to the caller based on context. Implement these exceptions using Java's specific built$-$in types, avoiding general exceptions like java.lang.Exception. Ensure catch and finally blocks print relevant information for debugging. Gather information on exception handling from reliable sources and create an APA$-$formatted reference list!! Develop a hypothesis on which Unchecked Exceptions to add and justify their inclusion and handling method. Analyze the rationale for these choices, evaluate their effectiveness in improving code stability, and conclude with reflections on the process and outcomes.
