Assert Exceptions

What is assert exception in Java?

• a) A feature that allows testing program assumptions and throws AssertionError if false.
• b) A method used to handle exceptions in Java programs.
• c) An error thrown by the JVM when an assertion fails.
• d) A keyword used to define custom exceptions in Java.

Can you assert an exception?

• a) No, assertions can only be used for testing boolean expressions.
• b) Yes, assertThrows() method enables asserting the occurrence of expected exceptions.
• c) No, assertions are only used for handling programming errors.
• d) Yes, assert keyword is used to throw custom exceptions.

How to assert if an exception is thrown in Java?

• a) By using the assertThrows() method in JUnit 5 tests.
• b) By catching the exception using try-catch block.
• c) By using the assert keyword with the expected exception type.
• d) By using the assertTrue() method in test classes.

How do you assert exceptions in a test class?

• a) By using assertNotEquals to compare exception objects.
• b) By using System.assert() to verify specific conditions.
• c) By using the assertThrows() method in JUnit 5 tests.
• d) By using assertTrue() to check if an exception is thrown.

Why use assert in Java?

• a) To handle runtime exceptions thrown by the program.
• b) To check if the control flow of the program is correct.
• c) To validate logical assumptions and verify return values.
• d) To handle exceptions caused by external influences.

Is assert an exception or error?

• a) Assert is an exception thrown by the JVM.
• b) Assert is an error thrown by the JVM.
• c) Assert is used to handle exceptions in Java programs.
• d) Assert is used to detect programming errors.

What is assert method in Java?

• a) A method to handle assertions in Java programs.
• b) A method to define custom exceptions in Java.
• c) A method to verify logical assumptions in Java programs.
• d) A method to catch and handle runtime exceptions.

Does assert throw an exception?

• a) No, assert does not throw any exception.
• b) Yes, assert throws AssertionError if the condition is false.
• c) No, assert only prints an error message without throwing any exception.
• d) Yes, assert throws a custom exception specified by the programmer.

What is the difference between an exception and an assertion?

• a) Assertions are used to handle runtime exceptions, while exceptions detect programming errors.
• b) Assertions are used to validate logical assumptions, while exceptions handle exceptional conditions.
• c) Assertions are custom exceptions, while exceptions are thrown by the JVM.
• d) Assertions are used for input validation, while exceptions handle control flow errors.

Why do we need assertions?

• a) To share information, coordinate actions, defend arguments, and communicate beliefs.
• b) To execute specific program statements based on certain conditions.
• c) To terminate the execution of a program when an error is encountered.
• d) To validate user input and handle exceptional situations.
