Program Plan Intro

Program Plan-

  • To create a class Test_des whose objects will invoke the constructors.
  • To define the destructors to print a message when they are called.
  • To create objects of this class in a test program called throw an exception.

Summary Introduction- The program demonstrates that before any exception is thrown from a block, the destructors for all the constructed objects are called first.

Program Description- The purpose of the program is to demonstrate that before any exception is thrown from a block, the destructors for all the constructed objects are called first.

Students have asked these similar questions
(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.
(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;       public…
(Member Object Destructors) Write a program illustrating that member object destructorsare called for only those member objects that were constructed before an exception occurred.
