Question

Q.21 What is an exception?
a) Problem arising during compile time
b) Problem arising during runtime
c) Problem in syntax
d) Problem in IDE​

Answer 1

Answer:

b

Explanation:

The problems that might occur during execution of a program are known as exceptions. The exceptions are unexpected sometimes and can be predicted. Also, the exceptions should be always considered for a better program.

Answer 2

Answer:

Concept:

The practice of reacting to the occurrence of exclusions or extraordinary events requiring special processing during its execution of a programme is known as exception handling in computing and computer programming. Whether it is a hardware and/or software exceptions and how the software exception is handled determine the specifics of how this is done. In general, an exception interrupts the usual flow of execution and executes a which was before exception handler. If offered, exception handling is made easier by specialized programming language constructs, hardware features like interrupts, or IPC features like signals supplied by operating systems (OS). Some exceptions, particularly those related to hardware, may be handled so smoothly that processing can pick up where it left off.

Answer:

The answer is option (b). Problem arising during runtime

Exceptions are issues that may arise while a programme is being executed. The exceptions may come as a surprise but are predictable.

Additionally, for a better programme, exceptions should always be taken into account.

Exceptions are issues that may arise while a programme is being executed. The exceptions may come as a surprise but are predictable.

An exception is a circumstance that arises while a programme is being executed and prevents the instructions from proceeding normally. A method that encounters an error creates an object and passes it on to the runtime system.

One of three reasons can be used to throw an exception: The Java virtual machine simultaneously identified an improper execution state. These circumstances exist because: evaluating an expression, such dividing an integer by zero, violates the language's regular semantics, as stated in Section 15.6.
