Chapter 22, Problem 22.21E
Program Plan Intro
- Create a file Test_Exception which throws an exception and the handler throws the same exception again.
- Run the program and record the result.
- To use names in any of the standard C++ header file:
- Header file contains classes used to handle exceptions.
- It contains runtime_error which is used in the program.
Summary Introduction- The program throws an exception. The handler that catches the exception throws it again.
Program Description- The purpose of the program to throw an exception and the handler catches the exception.

(Throwing Exceptions from a catch) Suppose a program throws an exception and the appropriate exception handler begins executing. Now suppose that the exception handler itself throwsthe same exception. Does this create infinite recursion? Write a program to check your observation.
(Creating Custom Exception Class) Write a Password class that stores a password string. Passwords must contain at least seven alpha-numeric characters, with at least one letter and one digit. Also write an InvalidPasswordException class that extends Exception. The Password constructor should throw an InvalidPasswordException, which should report an appropriate message based on a given string (e.g. if the string contains no digits, the exception should report this fact). Write a GUI program to prompt the user to enter a password and report an InvalidPasswordException if an invalid password is entered. Please teach and help me how to deisgn the program based on the two files given .Some sample screenshots are shown below:
InvalidPasswordException.java
public class InvalidPasswordException extends Exception{ public InvalidPasswordException (String errMsg){ super(errMsg); } }
Password.java
public class Password {private String passwordstr;

[Access Control Policy]: A computer system usually implements the exception
handling mechanism. Like the interrupt handling mechanism, the original program
flow will be stopped until the exception is handled. For example, when a program is
calculating c=a/b, and for some reason b was set to 0, the program will encounter
the "Division by Zero" exception. The control will be given to the exception handler,
and the recovery action could be "report only", "return to the next instruction",
"purge the program", etc., based on the severity of the problem. From the abov
information, we can conclude:
A computer system can integrate both Discretionary Access Control (DAC) and Mandatory
Access Control (MAC) security policies
An administrator can inhibit the exception handling
The exception handling mechanism is like the Mandatory Access Control security policy, no
matter which user caused the exception (even the administrator), the program should be
stopped, and the control should be given to the…

- Computer Science Help please! I need my code to use an exception handling method to check if the user entered a correct word. Here is the logic: When given two words, the child may claim that transformation of the first word into the second is possible. In this case, the program asks the child to demonstrate the correctness of the answer by typing a sequence of words starting with the first and ending with the second. Such a sequence is an acceptable proof sequence if each word is obtained from its predecessor by swapping a single pair of adjacent letters. For example, the sequence tops, tosp, tsop, stop, sotp, sopt, spot proves that the word tops can be transformed into spot. If the proof sequence is accepted, the child earns a point and play proceeds to the next round with a fresh pair of words. A proof sequence is rejected if a word cannot be obtained from its predecessor by swapping an adjacent pair of letters, or if the first word in the sequence is not the first word of the pair…arrow_forward(Local Variable Destructors) Write a program illustrating that all destructors for objectsconstructed in a block are called before an exception is thrown from that block.arrow_forward(Stack Unwinding) Write a program that throws an exception from a deeply nested function and still has the catch handler following the try block enclosing the initial call in main catchthe exception.arrow_forward
