Program Plan Intro
- • Create a class named “CoreBreachException” that extends “Exception”.
- ○ Define a default constructor that calls the parent class’s method using “super ()” by passing a message.
- ○ Define a parameterized constructor that calls the parent class’s method using “super ()” by passing a message that is given as the argument.
- • Create a class named “Main”.
- ○ Define the “main ()” method.
- ■ Create an object “e” for the class and pass a string as its argument.
- ■ Create an object “e1” for the class that does not contain any argument.
- ■ Get and print the message using the method “e.getMessage()”.
- ■ Get and print the message using the method “e1.getMessage()”.
- ○ Define the “main ()” method.

Define an exception class called CoreBreachException. The class should have a default constructor. If an exception is thrown using this zero- argument constructor, getMessage should return "Core Breach! Evacuate Ship!" The class should also define a constructor having a single parameter of type String. If an exception is thrown using this constructor, getMessage should return the value that was used as an argument to the constructor.
Define an exception class called CoreBreachException. The class should have a default

return "Cor Breach Evacuation Ship!" The class should also define a constructor having a single
parameter of type String. If an exception is thrown using constructor, getMessage should return
the value that was used as an argument to constructor.
Develop an exception class named InvalidMonthException that extends the Exception class. Instances of the class will be thrown based on the following conditions:
The value for a month number is not between 1 and 12
The value for a month name is not January, February, March, … December
Develop a class named Month. The class should define an integer field named monthNumber that holds the number of a month. For example, January would be 1, February would be 2, and so forth. In addition, provide the following methods:
A no-argument constructor that sets the monthNumberto 1.
An overloaded constructor that accepts the number of the month as an argument. The constructor should set the monthNumberfield to the parameter value if the parameter contains the value 1 – 12. Otherwise, throw an InvalidMonthException exception back to the caller. The exception should note that the month number was incorrect.
An overloaded constructor that accepts a string containing the name of the month,…

- Java question Write a Thermostat class such that a user of the Thermostat class can create an objectof Thermostat and set it to the desired temperature within a pre-specified range. If theuser tries set the temperature outside this range it should throw a TemperatureTooHighor TemperatureTooLow exception. Use inheritance to create an exception superclassTemperatureOutofRange and subclasses TemperatureTooHigh andTemperatureTooLow.Sample Tester code:Thermostat t = new Thermostat(0, 100);t. setTemp(50); // Should be OK.t.setTemp(150); // Should throw TemperatureTooHigh exception.t.setTemp(-50); // Should throw TemperatureToolLow exception.Write a Tester class to demonstrate throwing and catching of exceptions. Show that thecatch specifying the superclass catches the subclass exceptions. The order of exceptionhandlers is important. If you try to catch a superclass exception type before a subclasstype, the compiler would generate errors. Also show the re-throwing of exceptions.arrow_forwardin c # i need to Write the program BookExceptionDemo for the Peterman Publishing Company.
