To handle exceptions, use _____. A. try/catch B. the compiler C. methods D. common sense

Step 1: Break Down the Problem

The question asks for the mechanism used to handle exceptions in programming. We need to evaluate each of the given options to determine the correct answer.

Step 2: Relevant Concepts

1. Try/Catch: This is a programming construct that allows you to handle exceptions. Code that might throw an exception is placed in the 'try' block, and the 'catch' block is used to handle any exceptions that occur.
2. The Compiler: This is a tool that converts source code into executable code but does not directly handle exceptions.
3. Methods: Methods are functions defined within a class. While they can throw exceptions, they do not inherently handle them.
4. Common Sense: This is a general concept and does not relate directly to programming constructs.

Step 3: Analysis and Detail

• Option A (try/catch): This is the correct answer since it is a direct mechanism for exception handling in many programming languages, such as Java, C#, and JavaScript.
• Option B (the compiler): The compiler checks for syntax errors and compiles code but does not manage exceptions.
• Option C (methods): While methods may deal with exceptions if implemented, they are not a specific mechanism for handling exceptions.
• Option D (common sense): This is not a technical method for handling exceptions in programming.

Step 4: Verify and Summarize

By analyzing all the options, it's clear that the only one that directly deals with managing exceptions is the try/catch construct.

Final Answer

The correct answer is A. try/catch.
