What is the purpose of the 'try-catch' block?

To document the code structure for future reference To handle exceptions during runtime by separating error-prone code from error handling To improve code readability by organizing it into distinct sections To automatically optimize code execution for better performance

Correct Answer:

To handle exceptions during runtime by separating error-prone code from error handling

Explanation:

The 'try-catch' block is primarily utilized to handle exceptions during runtime, which is vital for building robust applications. By encapsulating potentially error-prone code within the 'try' portion, any exceptions that occur can be managed gracefully in the 'catch' section. This separation allows developers to anticipate and respond to errors without causing the program to crash. Instead, they can define specific actions to take when an error arises, such as logging the error, displaying a user-friendly message, or attempting a recovery process. This structured approach enhances the reliability of applications by ensuring that unexpected issues do not lead to complete failures, allowing for smoother user experiences and easier maintenance of the code.
