- Define a new "Exam" class that manages the exam name (string) and its score (integer). For example, an exam can have - "Midterm Exam", 100 - "Final Exam", 50 The class must not provide the default constructor. It must require the exam name and score in order to initialize the Exam object. The class must provide only the following methods (no more and no less): - isPerfect method that returns true if the score is exactly 100 and false otherwise. - isPassing method that returns true if the score is equal or greater than 70 and false otherwise. - toString method must return all the exam information including the result of the exam as a string in the following format: EXAM(<name>) SCORE(<score>) RESULT(Pass/Fail) such asEXAM(Midterm Exam) SCORE(100) RESULT(Pass) EXAM(Final Exam) SCORE(50) RESULT(Fail) "Pass" means the score is greater or equal 70.

- Define a class named Employee. This class should extend the Person class from the previous question. The class should have a constructor, which takes the name, age, employer (String) and salary (int) as parameters (in that order). The first two parameters should be passed to the constructor of the superclass and the value of the last two parameters should be stored in instance variables. The class should define the methods, getSalary which returns the salary of the employee and getEmployer which returns the name of the employer. Any methods from the previous question that need to be overridden should be overridden! Use super and instanceof as appropriate. I.e., for the following methods you should be able to call the method in the superclass for specific situations (e.g. the compareTo method in the superclass can be called if you receive anything other than an Employee, and this also holds for the equals method). The toString method only needs to append details and as such can also…Please answer these multiple choice questions 1) The new operator: allocates memory is used to create an object of a class associates an object with a variable that names it.

Create constructor, getters and setters. If one is to set the initial balance of an account as a negative value in a setter or a constructor, remind the user about the error and set it as 0. Create a CheckingAccountDemo class, and create a main method in which Ask for the name, account number, and initial balance for one account from the keyboard input. With these input values as arguments in a call to the constructor, create a CheckingAccount object. Print the summary of this account that includes information on the name, account number, and balance by calling the getters.

True or False: The parameterized constructors of Java does not accept any parameters instead, using these constructors the instance variables of a method will be initialized with fixed values for all objects. False True Give an explanation for the answer. Thank youDefine a class called Country. A Country has populationSize, area, capital, currency, and abbreviation (2-3 letters taken from the country name). Define at least two constructors, at least two getter methods, at least two setter methods, and Override the toString() and the equals() methods. The equals() method must return true if the two countries have the same name and same populationSize and false otherwise. The abbreviation is the first letter and the second letter of the country name and must be generated automatically (e.g. if the country name is Palestine the abbreviation is PA, if the country name is Jordan the abbreviation is JO.) Write a main method, define an array of country objects, read countries data from the user, if two countries have the same abbreviation add the last letter from the country name to the abbreviation of the country inserted last. Display countries whose area is greater than 10000 km2.
