Question

Which of the following statements about try blocks is true?

a. The try block must be followed by at least one catch block.
b. The try block must be followed by a finally block.
c. The try block should contain statements that may process an exception.
d. The try block should contain statements that may throw an exception.

Answer 1

A try block should contain code that may throw an exception. It is not mandatory to have a catch or finally block, but it is common practice to include at least one to handle exceptions or perform cleanup.

Step-by-step explanation:

The correct answer to the question about try blocks is that the try block should contain statements that may throw an exception. When a block of code within the try is executed, and if an exception arises, the control is passed to the corresponding catch block, if it exists, to handle the exception. It is not a requirement that a try block must be followed by a catch or a finally block, though it is typically accompanied by at least one of these.

A catch block is used to handle specific types of exceptions, which allows for graceful recovery or management of an error condition. The finally block is optional and provides a mechanism to execute code regardless of whether an exception was thrown or caught, typically for resource cleanup.
