(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:
(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: 41
Select the statement that is false regarding file guarding.
Group of answer choices:
In your .h files all code should be contained within the guards.
It restricts the scope of a namespace, which prevents namespace pollution.
If used properly it prevents redefinitions of classes/functions.
It is an instruction to the preprocessor.
It must make use of a unique identifier.

- Description: Create (Java Program) a phonebook directory that will store the contact numbers of N persons. Your program should allow the user to add, view, delete, and update the contacts in the phonebook. Note that one person can have multiple contact numbers. The program will stop when the user command is ‘X’. Program command and entry should not be case-sensitive. That means commands ‘I’ or ‘i’ and the name “Jacky” or “JACKY” are the same. Each contact number can be 7 digits or 11 digits only. The user should input a string containing the command, name, and contact number(s) (Limit the contact number of each person to three). This string should be broken down into fields in order to separate the different values and store them in their appropriate variables. Use linked list in the implementation.
