12.7. Multiple Catch Blocks

Try these first

1. 1.

   What is the purpose of using multiple catch blocks?

   Hint

   Think about the diversity of errors.

2. 2.

   Explain why it is important to catch specific exceptions before generic exceptions.

   Hint

   What happens if a general exception is caught first?

3. 3.

   What happens if a generic exception catch block is placed before a specific catch block?

   • The specific catch block will execute.
   • The generic catch block will execute.
   • Both blocks will execute.

   Hint

   Think about which catch block handles the exception.

4. 4.

   True or False: You can have multiple catch blocks handling the same type of exception.

   • True
   • False

   Hint

   Consider exception uniqueness.

5. 5.

   You are developing a file processing application. Write a Java method that reads a file and handles potential IOException, FileNotFoundException, and a hypothetical CustomFileException. Discuss how you will structure your catch blocks and why.

   Hint

   Think about how you'd handle missing files versus custom processing errors.

6. 6.

   Consider an application where users can divide numbers. Write the code to handle Division by Zero, and invalid format exceptions. Explain the importance of each catch block.

   Hint

   Reflect on the types of inputs a user might provide.
