Have you ever seen a Java File close() throw an exception?

Question

Has anyone ever seen an exception thrown when calling close method on any closable object?

Answer 1

Old post and long since answered but here's a real example:

The following code will except out when bufferedWriter.close() is called. This happens because the BufferedWriter's underlying Writer (the FileWriter) has already been closed and when a BufferedWriter closes, it first attempts to flush any data in its buffer to its underlying Writer.

File newFile = new File("newFile.txt");

FileWriter fileWriter = new FileWriter(newFile);
BufferedWriter bufferedWriter = new BufferedWriter(fileWriter);

bufferedWriter.write("Hello World");

fileWriter.close();
bufferedWriter.close();

Note: If there's no data in the buffer [comment out the write() line or add a flush() call] then no exception will be generated
