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.

JAVA Problem – CycleFileInput Revisit the Cycle class . Modify your application such that the properties will be read from a text file called “Cycle.txt”. Directions Examine your application for the class called Cycle. Add an appropriate throws statement in the main method. Create a reference to a File class with the appropriate name of a text file (Cycle.txt). Note: Cycle.txt was created in the previous assignment, CycleFileOutput. In your code, check that the text file does exist. Input the values from the file to memory. Close the file. public class Cycle { // Declear integer instance variable private int numberOfWheels; private int weight; // Constructer declear class public Cycle(int numberOfWheels, int weight ) { this.numberOfWheels = numberOfWheels; this.weight = weight; } // String method for output public String toString() { String wheel = String.valueOf(this.numberOfWheels); String load = String.valueOf(this.weight); return("No of wheels in cycle = " +…
