Write a Java enumeration LetterGrade that represents letter grades A through F, including plus and minus grades. Define a private instance vari- able to hold a boolean value that is true if the grade is passing. Also, define a constructor that initializes this instance variable, an accessor method is- Passing to return its value, and a method toString that returns the grade as a string. Finally, write a program to demonstrate the enumeration.

Write a class that implements Employee class that is described in UML diagram given below. The method “ raiseSalary(percent) " increases the salary by the given percentage. Write a test program that will generate at least 3 accounts and test each method that you write. Employee -id:int -firstName:String -lastName:String -salary:int +Employee(id:int, firstName:String, lastName:String, salary:int) +getID():int +getFirstName():String +getLastName():String +getName():String +getSalary():int +setSalary(salary:int):void +getAnnualSalary():int • +raiseSalary(int percent):int +tostring():String. "firstName Llastname" salary * 12 Increase the salary by the percent and return the new salary "Employee[id=?,name=firstName lastname,salary=?]"
using python language Suppose a call center has three levels of employees—respondent, manager, and director. An incoming telephone call must first be allocated to a respondent who is free. If the respondent cannot handle the call, the call must be escalated to a manager. If the manager is occupied, then the call should be escalated to a director. Design your own classes and data structures for this problem. Implement a method dispatchCall() that assigns a call to the first available employee.
Write a class with a constructor that accepts a String object as its argument. The class should have a method that returns the number of b, c, d, f, g, h, and z in the string. Demonstrate the class in a program that asks the user to enter a string and returns the number of b, c, d, f, g, h, and z in the user string.
Define a class in java representing physical elements (like hydrogen, helium, lithium,etc.). Elements have a name, a symbol, an integer atomic number, and an atomicweight (which may be fractional). Your class should have a constructor that setsall the properties, and a toString method that prints each element as a nicelyformatted String. Write accessors and mutators for each field if you think it isappropriate to do so (ask yourself if the field should be changeable). Update yourmain method to create and print 10 unique elements.
For the Employee class, create the following: A private String instance variable m name. A private string instance variable m department. A constructor that takes two parameters (in the order of name, department) and sets the instance variables. A getter method for m name and a getter method for m department. An abstract string method named getPaycheck that does not take any parameter.
Write a program in java Design a class that holds the following personal data: name, address, age, and phone number.Write appropriate accessor and mutator methods. Demonstrate the class by writing aprogram that creates three instances of it. One instance should hold your information, andthe other two should hold your friends’ or family members’ information.
write a java program This composition example contains classes Date, Employee and EmployeeTest .Class Date declares instance variables month, day and year to represent a date. The constructor receives three int parameters. It has checks to validate the month—if the value is out-of-range the method throws an error message, same goes for day. Provide getters, setters and toString method. Class Employee has instance variables firstName, lastName, birthDate and hireDate. firstName and lastName are references to String objects. Members birthDate and hireDate are references to Date objects. • The Employee constructor takes four parameters—first, last, dateOfBirth and dateOfHire. Initialize the hireDate and birthDate with these objects by calling its constructor and setters. • When class Employee’s toString method is called, it returns a String containing the employee’s name and the String representations of the two Date objects. Each of these Strings is obtained with an implicit call…
Programing language is Java. Define a class Person that represents a person. People have a name, an age, anda phone number. Since people always have a name and an age, your class shouldhave a constructor that has those as parameters. Define a toString() method whichdisplays all of the relevant information using a format like this: “Jim Lahey - Age 57- Phone 9025555555”.
Write Java code for a Baby class. A Baby has a name of type String and an ageof type integer.Supply two constructors: one will be the default constructor, that just setsdefault values for the name and age; the second constructor will take twoparameters, a string to set the name and an integer to set the age. Also, supplymethods for setting the name, setting the age, getting the name and getting theage.The class should not contain I/O methods; input of values to the instancevariables must be done with a set method or constructor, output of values fromthe instance variables must be done with get methods. The set method for thename instance variable should ensure that the input is not empty or containwhitespaces (otherwise set a default value). The set method for the ageinstance variable should validate the input to be between 1 and 4 inclusive(otherwise set a default value).Give Java code for an equals method for the Baby class. Babies count asbeing the same (i.e. equal) if their names…
1/ Implement a class Employee. An employee has a name (a string) and a salary (a double). Provide a constructor with two arguments public Employee(String employeeName, double currentSalary) and methods public String getName() public double getSalary() public void raiseSalary(double byPercent) These methods return the name and salary, and raise the employee's salary by a certain percentage. Sample usage: Employee harry = new Employee("Hacker, Harry", 50000); harry.raiseSalary(10); // Harry gets a 10 percent raise Supply an EmployeeTester class that tests all methods. 2/Implement a class Car with the following properties. A car has a certain fuel efficiency (measured in miles/gallon or liters/km—pick one) and a certain amount of fuel in the gas tank. The efficiency is specified in the constructor, and the initial fuel level is 0. Supply a method drive that simulates driving the car for a certain distance, reducing the amount of gasoline in the fuel tank. Also supply methods…

Note: Write a Java program given below Question # 1: Define a class for Students with field name, age, marks. Define getter and setter for all the fields. In the setter method, if age is less than 0, print that Age is less than zero. Similarly, if marks is less than zero or greater than 100, print in correct marks and don’t assign marks to member variable. In the Test class, create student’s object and assign the marks and age to appropriate values. Try assigning incorrect values to check if getter and setter methods work as expected.
