Define the class InvalidSideException, which inherits from the Exception class. Also define a Square class, which has one method variable -- an int describing the side length. The constructor of the Square class should take one argument, an int meant to initialize the side length; however, if the argument is not greater than 0, the constructor should throw an InvalidSideError. The Square class should also have a method getArea(), which returns the area of the square.Create a Driver class with a main method to test your classes. Your program should prompt the user to enter a value for the side length, and then create a Square object with that side length. If the side length is valid, the program should print the area of the square. Otherwise, it should catch the InvalidExceptionError, print "Side length must be greater than 0.", and terminate the program.

Java Programming: Below is the lexer, shank and token files along with the shank.txt file. The shank file is the main method file. The lexer must break up the input text stream into lexemes and return a token object for each one in the shank.txt file. Make sure to fix the errors in the lexer.java file and show the complete code for lexer.java.There must be no error in the code at all. Run the whole code and show the output which the shank.txt must be printed out in the terminal. Attached is the rubric.

write a java programme:
Vehicle class:First create an abstract Vehicle class that contains code common to all of the vehicles.1. Vehicle class has a color, IDnumber, and a model.2. Throw an exception named “InputNotCorrectException” if the IDnumber is negative.3. The accessor and mutator methods for all three data fields.4. Also include a void wheels() method which is declared abstract.
Runnable interface:1.Deaclare an abstract method named HowToRun() which has a return type of void.
Car class:Car class is a subclass of Vehicle which implements the Runnable interface.1. Write a class called Car which extends the Vehicle class and implements the Runnable interface.2. Override the equals method in the Object class. Two Car objects are equal if their models are thesame.3. In the Car class override the wheels() method to display “A car has four wheels”.4. A method named toString() that returns a string description for the car.5. Override the HowToRun() method to display “A car runs with…

Use constructor to initialize data members of the Fan class. Create function on() and off() to switch on and off the fan respectively. Create a function speedup() is to increase the speed of the fan by 1 if speed of the Fan greater than 5 it should throw a custom exception. Create another function speeddown() is to decrease the speed of the fan by 1 if speed of the Fan less than 0 it should throw a custom exception.

This class should also have an additional method for calculating the modulo. The modulo method should only be seen at the sub class, and not the base class! Include exception handling for instances when dividing by 0 or calculating the modulo with 0. You would need to use throw, try, and catch. The modulo (or "modulus" or "mod") is the remainder after dividing one number by another.Example: 20 mod 3 equals 2Because 20/3 = 6 with a remainder of 2 Refer also to the attached sample outputs:arrow_forwardWrite an application TestStudent that prompts for and reads a student name. It then creates a Student object. It then prompts for and reads the number of quizzes n that the student has taken. It then prompts for and reads the scores of the student in n quizzes and adds each to the totalScore of the student using addQuiz() method. Finally, the application prints the student object using the toString() method, and it also prints his quiz average. The main method must handle java.util.InputMismatchException, java.lang.IllegalArgumentException and java.lang.Unsupported OperationException.arrow_forward
- JAVA Write a class named TestScores. The class constructor should accept an array of test scores as its argument. The class should have a method that returns the average of the test scores.

Write the application SwimmingWaterTemperature containing a variable that can hold a temperature expressed in degrees Fahrenheit. Within the class, create a method that accepts a parameter for a water temperature and returns true or false, indicating whether the water temperature is between 70 and 85 degrees and thus comfortable for swimming. If the temperature is not between 32 and 212 (the freezing and boiling points of water), it is invalid, and the method should throw an ArgumentException. In the Main() method, continuously prompt the user for data temperature, pass it to the method, and then display the following messages indicating whether the temperature is comfortable, not comfortable, or invalid: X degrees is comfortable for swimming.

(sub classes) If a person, you will ask them (using scanner) to enter their First Name, Last Name, Street Address and Phone Number (all should be strings.) If they are a teacher, they will enter all the person info, plus the number of years teaching as an int.(scanner) If they are a student, they will enter all the person info, plus year of graduation as an int and GPA as a double.(scanner) Each class should have a default constructor that initializes strings to a blank string and all ints or doubles to 0. You should then have an overloading constructor that takes in the information. Remember sub-classes inherit the super classes constructor. All three classes will then have an overriding method named printInfo.
