Java program Make a class Employee with a name and salary. Make a class Manager inherit from Employee. Add an instance variable, named department, of type String. Supply a method toString that prints the manager’s name, department, and salary. Make a class Executive inherit from Manager. Supply appropriate toString methods for all classes. Supply a test program that tests these classes and methods.
In Java Write a bank account program that handles bank account balances for an array of bank accounts. There aretwo types of bank accounts ─ checking and savings. Use this UML class diagram:BankAccountChecking SavingsImplement the following classes and methods.BankAccount class:Instance variable:balancedeposit method ─ add the given amount to the current balance.Withdraw method ─ subtract the given amount from the current balance. Don’t allow the balance togo below zero. If the balance does go below zero, change the balance to zero.display method ─ This must be an abstract method.Checking class:No new instance variables.writeACheck method ─ subtract the given amount from the current balance and then subtract anadditional $1 as part of a service fee.display method ─ print the type of account, checking, and then the balance (with standard currencyformat). Study the output for details.Savings class:Instance variable:intRate (interest rate)addInterest method ─ calculate the interest by…

# Coding - Simulate a robot Write a program that simulates the movements of a robot. The robot can have three possible movements: turn right turn left advance The robot is placed on a hypothetical infinite grid, facing a particular direction (north, east, south, or west) at a set of `{x,y}` coordinates,e.g., `{3,8}`, with coordinates increasing to the north and east. Create a Class `Robot` that contains a method `execute` which given a number of instructions will calculate the robot's new position, and the the direction in which it is pointing. ## Example The letter-string "RAALAL" means: Turn right Advance twice Turn left Advance once Turn left yet again Say a robot starts at `{7, 3}` facing north. Running this stream of instructions should leave it at `{9, 4}` facing west. ## Inputs and Outputs The argument of the `execute` is `string` in the format `X Y BEARING COMMANDS`. The method should return a one-liner `string` in the format `X Y BEARING`. In the…

class Point with instance variables as: xCoordinate(int) and yCoordinate(int). Write public instance methods (getters & setters) for each instance variable. Now, write a class Circle with private instance variables as radius and Pi (value is 3.14). Write public setter, getter for radius, Area method for calculating Area, Draw method for radius. Formula for calculating area=pi*r^2 Formula for calculating radius=Math.sqrt(xCordinate^2+yCordinate^2) Extend a Circle class from Point class such as Class Circle extends Point Write a Default constructor in Circle class that sets radius, xCoordinate&yCoordinate to some default value e.g. -1; Write a Parameterized constructor in Circle class which takes xCoordinate, yCoordinate and radius as a parameter. E.g. Circle (int xCoordinate, int yCoordinate, double radius) { this.xCoordinate= xCoordinate; this.yCoordinate= yCoordinate;…
Java - Access Specifiers Create a class named Circle that has attributes radius, area, and circumference and make the attributes private. Make a public method that sets the radius and a method that prints all attributes. Ask the user input for radius. Note: Use the PI from the math functions Inputs A line containing an integer 10 Sample Output Radius: 20 Area: 1256.64 Circumference: 125.66
The BankAccount class described below is used to represent a personal savings account with a yearly interest rate, (represented as a percentage, e.g., a 7% rate is represented by .07). The interest is applied monthly, (i.e., at the end of each month 1/12 of the interest is deposited into the account). public class BankAccount { public BankAccount(double rate) public BankAccount(double initBal, double rate) public double getBalance() public double getIntRate() public void setIntRate(double rate) public void deposit(double amount) public void withdraw(double amount) public void addMonthsInterest() private double balance; private double intRate; } Suppose a bank offers to its special customers a new type of savings account, called a “Credit Account”, that allows the customer to withdraw extra money if needed, so that the account balance is allowed to be negative at some times. These accounts award interest at the end of every month, as long as the balance is positive. If the…
Override the testOverriding() method in the Triangle class. Make it print “This is theoverridden testOverriding() method”. (add it to triangle class don't make a new code based on testOverriding in SimpleGeometricObject class.) (this was the step before this one) Add a void testOverriding() method to the SimpleGeometricObject class. Make it print“This is the testOverriding() method of the SimpleGeometricObject class”
1/ Write a BankAccountTester class whose main method constructs a bank account, deposits $1,000, withdraws $500, withdraws another $400, and then prints the remaining balance. Also print the expected result 2/ 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. 3/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…

Why or why not? Which of the Dog class's methods are accessors? Which ones are mutators? Can you use the methods provided to make a dog younger? (In other words, can you set age to a lower value than it already was?)…
