Resource Management: Closeable File Logger

In this problem: You will create a FileLogger class that implements the Closeable interface, and use a try-with-resources statement to ensure the resource is properly closed.

Learning Objective: Understand resource management using the Closeable interface and try-with-resources statement

Overview

In Java, resources like files and DB connections must be closed after use. By implementing the Closeable interface and using try-with-resources, close() is guaranteed to be called automatically even when exceptions occur.

Specifications

• FileLogger class (implements Closeable)
  • Constructor: prints "FileLogger opened"
  • void write(String message): prints "Writing: " + message
  • void close(): prints "FileLogger closed"
• Main class
  • Creates FileLogger in a try-with-resources statement
  • Calls write("Hello")
  • Calls write("World")
  • Prints "Done" after the try-with-resources block ends

Output Format

FileLogger opened
Writing: Hello
Writing: World
FileLogger closed
Done
