Examples of Checked Exceptions: SQLException, IOException, FileNotFoundException

Quick Answer

The correct answer is FileNotFoundException, along with SQLException and IOException, as these are all checked exceptions in Java. A checked exception is any class that extends Exception but not RuntimeException, meaning the compiler forces you to handle it with a try-catch block or declare it in the method signature using the throws clause. On the Oracle Java Foundations 1Z0-811 exam, you will often see checked exceptions examples like these to test your understanding of compile-time error handling versus runtime exceptions. A common trap is confusing SQLException with an unchecked exception because it involves database errors, but since it directly extends Exception, it is checked. Similarly, FileNotFoundException and IOException are thrown during file operations and must be handled explicitly. To remember, think of the acronym SIF: SQLException, IOException, FileNotFoundException—all three force you to write handling code before your program will compile.
