Chapter 16: Problem 2

The ____________ block should enclose code that directly or indirectly might cause an exception to be thrown.

Short Answer

Expert verified
Answer: The block is named the "try" block. Its purpose is to enclose code that might cause an exception to be thrown, allowing the program to continue running and handling the exception using associated "catch" blocks without crashing.

Step by step solution

01

Identify the block

The correct name of the block that should enclose code that directly or indirectly might cause an exception to be thrown is the "try" block.
02

Explain the purpose of the try block

When writing code that could potentially generate an exception, we use a try block. The try block is used to enclose the code that might cause an exception. If an exception is thrown within the try block, it won't crash the program; instead, it will be caught and handled by an associated "catch" block.
03

Describe the use of catch blocks

Catch blocks are used to handle exceptions thrown within the try block. When an exception occurs, the appropriate catch block is executed, and the program continues to run after the catch block's end. Generally, a try block should be followed by at least one catch block or a finally block. Catch blocks should be written to handle different types of exceptions that can be thrown by the code within the try block.
04

Mention the finally block (optional)

A finally block can also follow a try block. The finally block is used to perform any necessary clean-up actions that should be executed regardless of whether an exception occurred or not. This block is executed after the try block completes its execution, whether an exception was thrown or not. It is important to note that a try block can have one or more catch blocks and an optional finally block, but should have at least one of them.
