Answer:
We need to explain the what are the correct option regrading the error handling and exception . so we will see in the more details explanation.
Step by step
Solved in 2 steps
- In a few well-written paragraphs, discuss the use of exceptions and exception handling in programming. Your discussion should include definitions for exception, exception handler, throw signal, and catch process. Discuss why exceptions are helpful for handling runtime errors, such as division by zero.We have created a hierarchy of exceptions like below: A) The code written below throws an exception from the above hierarchy, depending on the value of c. Fill in the 5 gaps below, so that a correct working program is created. B) the following code throws two exceptions: Exception and ExceptionD. The exception name in the catch statement was removed as I expect you to recognize the order by which the exceptions are written in this code. B-1) what will be printed if the method is called by x = 0. B-2) what will be printed if the method is called by x = -1. B-3) what will be printed if the method is called by x = 1. C) A class called Exam is defined as below. Another class called TT2 extends class Exam and overrides all the three methods of Exam class. Specify what type of exceptions can be thrown by the methods that are defined in class TT2.Is there any way to skip Finally block of exception even if some exception occurs in the exception block?
- 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.What is the catch phrase? What is a finally clause? How do both catch and finally work in an exception program?Q. If we don't know exception type, what type should we mention in catch block ?
- JAVA Given a main program that searches for the ID or the name of a student from a text file, complete the findID() and the findName() methods that return the corresponding information of a student. Then, insert a try/catch statement in main() to catch any exceptions thrown by findID() or findName(), and output the exception message. Each line in the text file contains the name and the ID of a student, separated by a space. Method findID() takes two parameters, a student's name and a Scanner object containing the text file's contents. Method findID() returns the ID associated with the student's name if the name is in the file, otherwise the method throws an Exception object with the message "Student ID not found for studentName", where studentName is the name of the student. Method findName() takes two parameters, a student's ID and a Scanner object containing the text file's contents. Method findName() returns the name associated with the student's ID if the ID is in the file,…PLZ help with the follwoing IN JAVA Suppose that statement2 causes an exception in the following try-catch block: Will statement3 be executed? If the exception is not caught, will statement4 be executed? If the exception is caught in the catch block, will statement4 be executed?If we don't know exception type, what type should we mention in catch block ?
- Has a catchphrase been used? What exactly does a finally clause mean? How do catch and finally operate in an exception program?Which of the following is a good example of the definition of a custom exception type?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.
