Which action will raise an exception? MCQ

Understanding “Which Action Will Raise an Exception MCQ”

An important part of programming includes handling errors and dealing with exceptional cases. That's where the concept of “Exceptions” comes in. One frequently discussed question when learning about exceptions has the keyword “Which action will raise an exception mcq”. This query refers to multiple-choice questions (MCQs) related to actions in programming languages that can cause exceptions.

Exceptions commonly arise during run time due to incorrect code sequences. They occur as a result of assigning a string such as “Hi” to an integer variable, for instance. Expanding one's knowledge and understanding how to prevent or handle these exceptions increases one's efficiency as a programmer.

Table Summary

What are Exceptions?

Exceptions refer to particular conditions that occur during the execution of a program. These are unusual or extraordinary conditions that the code in a program cannot handle.

When Do Exceptions Arise?

Exceptions primarily arise during runtime, especially when the code sequence is incorrect. This includes scenarios where you assign a string (like “Hi”) to an integer variable. Such an action will raise an exception.

Exception Handling and Its Importance

Exception handling refers to the process of responding to the occurrence of these exceptions. It is crucial in programming to ensure that the program can continue to function in the face of unforeseeable errors, without terminating abruptly.

Checked Vs. Unchecked Exception

In Java, exceptions are categorized as checked or unchecked. A checked exception involves conditions that a well-written application should anticipate and recover from. On the other hand, unchecked exceptions represent defects in the code which the application usually cannot recover from.

Which Keyword is Used to Raise an Exception

In Python, the 'raise' keyword is used explicitly to throw an exception, enabling programmers to create their custom exceptions and error messages, thus contributing to robust and stable code.

In conclusion, understanding “which action will raise an exception mcq” is crucial for any programmer, as it enhances proficiency and helps produce more efficient codes.
