- Suppose there exists a catch handler that matches the exception object type perfectly. Under what circumstances may exception objects of this type be treated differently?Let's say there is a catch handler that exactly matches the exception object type. What are the conditions in which exception objects of that type could be handled differently?What is exception propagation? Give an example of a class that contains at least two methods, in which one method calls another. Ensure that the subordinate method will call a predefined Java method that can throw a checked exception. The subordinate method should not catch the exception. Explain how exception propagation will occur in your example.
- Let us assume that there is a catch handler that perfectly fits the kind of exception object being thrown. What are the circumstances in which exception objects of that type could be treated differently than they normally would be?Assume a catch handler matches the exception object type. What situations allow exception objects of that type to be handled differently?Write a JAVA PROGRAM to create a user defined exception class. In this, a constructor of InvalidGradeException accepts a string as an argument. This string is passed to constructor of parent class Exception using the super () method. Also the constructor of Exception class can be called without using a parameter and calling super () method is not mandatory. WRITE JAVA PROGRAM only, and give screenshot of sample run
- Write a program that demonstrates how various exceptions are caught with catch (Exception exception) 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.Write a program that shows a constructor passing information about constructor failure to an exception handler. Define class SomeException, which throws an Exception in the constructor. Your program should try to create an object of type SomeException and catch the exception that is thrown from the constructor.How can the standard error message be shown when an exception is thrown?
- Create user defined Exception Class for Age, if age is zero or less than zero throw exception with message marks should be greater than zero. For this you should take marks input from User, Design window in WPF for Testing User defined exception class? [CLO -3 PLO-2,In Java when a method throws a checked Exception, what must we always do when calling that method? A. Make sure to declare the method as static. B. Put it inside a try/catch block. C. Set the permission level of the method to private. D. Check our input, and if it will be bad input we must throw an exception before calling the method.Write a program that calls a method that throws an exception of type ArithmeticExcepton at arandom iteration in a for loop. Catch the exception in the method and pass the iteration countwhen the exception occurred to the calling method by using an object of an exception class youdefinein java code
