How does try/catch(exception) processing help resolve run time exceptions?

What is a custom exception? What are it's benefits?

What does it mean when we raise a custom exception?

Solutions

Expert Solution

With the help of try/catch processing, we can avoid abrupt termination of the program. With catch block, we can do custom handling for each type of exception.

A custom exception is a user-created exception. Some of its benefits are:

  • Provides error-specific information
  • Allows more fine-grained exception handlers.

When we raise a custom exception, it means that we expect the code to throw this exception.

JAVA Write a program that demonstrates how various exceptions are caught with catch (Exception exception) This time, define classes ExceptionA (which inherits from class Exception) and ExceptionB (which inherits from class ExceptionA). In your program, create try blocks that throw exceptions of types ExceptionA, ExceptionB, NullPointerException and IOException. All exceptions should be caught with catch blocks specifying type Exception.

Raising an Exception In the previous problem, you used a try/except statement to catch an exception. This problem deals with the opposite situation: raising an exception in the first place. One common situation in which you will want to raise an exception is where you need to indicate that some precondition that your code relies upon has not been met. (You may also see the assert statement used for this purpose, but we won’t cover that here.) Write a function...

For practice using exceptions, this exercise will use a try/catch block to validate integer input from a user. Write a brief program to test the user input. Use a try/catch block, request user entry of an integer, use Scanner to read the input, throw an InputMismatchException if the input is not valid, and display "This is an invalid entry, please enter an integer" when an exception is thrown. InputMismatchException is one of the existing Java exceptions thrown by the Scanner...
