Question
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.

(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). Use java swing to write a GUI program to prompt the user to enter a password and report an InvalidPasswordException if an invalid password is entered. Some sample screenshots are shown below:

- (True/False): When the source code of a program is amended, it must be reassembled and linked before the updated code may be run.arrow_forward[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…arrow_forward(Convert decimals to fractions)Write a program that prompts the user to enter a decimal number and displays the number in a fraction.Hint: read the decimal number as a string, extract the integer part and fractional part from the string, and use the Rational class in LiveExample 13.13 to obtain a rational number for the decimal number.

- please fix the issue hihlighted in yellow and please check my code. In python language: Write a program that reads integers user_num and div_num as input, and output the quotient (user_num divided by div_num). Use a try block to perform all the statements. Use an except block to catch any ZeroDivisionError and output an exception message. Use another except block to catch any ValueError caused by invalid input and output an exception message. Note: ZeroDivisionError is thrown when a division by zero happens. ValueError is thrown when a user enters a value of different data type than what is defined in the program. Do not include code to throw any exception in the program. Ex: If the input of the program is: 15 3 the output of the program is: 5 Ex: If the input of the program is: 10 0 the output of the program is: Zero Division Exception: integer division or modulo by zero Ex: If the input of the program is: 15.5 5 the output of the program is: Input Exception: invalid literal for…arrow_forward(In java) Lab6C: Cha-Ching For this lab, use a do-while loop.A sentinel loop is a loop (a special while loop or a do-while loop) that continues to process data until itreaches a specific value(s) that signals that it should stop looping; this special value(s) is usuallyindicated as the condition of the while or do-while loop. A good example of a sentinel loop is the whileloop that you had to write to verify user input in Lab6B, the special values were anything in the range of1 to 1000. Another very common application for this is allowing a user to rerun a program.Please write a very simple program that mimics a bank account. The program should start the user outwith $1000. The program should print out a welcome menu once with the options present for the user.The program should allow the user to make a deposit, withdrawal, and see their current balance.Every time the user deposits or withdraws, the program should show the user their new balance; itshould also ask the user if they want…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
- (NumberFormatException)Write the bin2Dec(String binaryString) method to convert a binary string into a decimal number. Implement the bin2Dec method to throw a NumberFormatException if the string is not a binary string. Write a test program that prompts the user to enter a binary number as a string and displays decimal equivalent of the string. If the method throws an exception, display "Not a binary number".Sample Run 1Enter a binary number: 1015Sample Run 2Enter a binary number: 41Not a binary number: 41arrow_forwardGive the names of the three techniques for dealing with exceptions.arrow_forwardChecked exceptions in Java are those exceptions that are checked at compile time and must be either caught or declared in the method's throws clause.
