I need to override the toString() method with my own, however I am not sure how to reference back to the parameters for the constructor of the class. I've included my code below. I even tried giving the class instance variables of the same name, however the error said the code was "unreachable." What am I doing wrong?
/**

public class Appointment {
/**

Redefine the equals method of the class Date (Display 4.13) so that it hasa parameter of type Object and follows the other guidelines we gave for anequals method. (Remember, you should use getClass(), not instanceof.)
I am trying to add int instance variables for the current hour and minutes of a clock, and I am trying to make them private. I am also trying to write getHour and getMinutes getter methods for these instance variables. I would like to know if I did this correctly and if not, I would like assistance as to what I could change.
public class DigitalClock {
private int currentHour; private int currentMinutes;
public int getHour() { return currentHour; }
public void setHour(int currentHour) { this.currentHour = currentHour; }
public int getMinutes() { return currentMinutes; }
public void setMinutes(int currentMinutes) { this.currentMinutes = currentMinutes;}}

- I need to figure out how to call a method that is located in a different class. For example, I am trying to make a tax calculator that multiplies a payers income by a corporate rate. However, I cannot figure out how to call the income method. Nothing I have tried is working. Is there any chance you can guide me? I am just trying to make this equation work. Is there something else that is stopping this from working?arrow_forwardIs this overload constructor? But what is behavior methods? Do I need to add walk, feed and bark into the code? See code below: Overload constructor? public String getName() {return name;}public String getBreed() {return breed;}public int getAge() {return age;} package dog1; public class Dog1 { String name;String breed;int age;public Dog1(String name, String breed, int age) { this.name = name;this.breed = breed;this.age = age;}public String getName() {return name;}public String getBreed() {return breed;}public int getAge() {return age;}@Overridepublic String toString() {return ("My name is " +this.getName()+".\nMy breed and age are: "+this.getBreed()+","+this.getAge());}public static void main(String[] args) {Dog1 chico = new Dog1("Chico", "Pitbull",5);System.out.println(chico.toString());}} How can I add walk, feed and bark?arrow_forwardDefine a Static method 'max' with return type as 'int' in class 'ProblemSolution' that take two numbers with type 'int'. Inside the 'max' method, compare the two numbers and return the maximum of the two numbers. Then, inside the 'main' method. Define two 'int' type numbers; the first number (num1) is equal to 5 and the second number (num2) is equal to 2. At the next line, call the 'max' method where its parameter input are the two numbers above, and assign the result of the method to the variable num3 (type 'int'). Finally, on the next line, print out -> "The maximum of " + num1 + " and " + num2 + " is " + num3 Output The maximum of 5 and 2 is 5 Where, There must be space between all the words and numbers. There should not any space after the last numberarrow_forward
- In Java, Use the Phone class as a baseline, and write a method isUSA. It should return true if the country code is 1 and false otherwise. Also expanding the Phone class, write a method that determines the location of an area code. It should return the name of the area code's city. For example, if cc = 1 and area code = 510 East Bay Area, 650 SF Peninsula, 415 San Francisco, 408 South Bay Area. For this assignment, use literal strings as return values.arrow_forwardbox1 and box2 are instances of the Box class. Attributes length, width, and height of both box1 and box2 are read from input. Then, two strings are read from input. In the Box class, define instance method print_measurements() with self and one string as parameters to output the string parameter in one line, and the following in the next line: The value of attribute length ' by ' The value of attribute width ' by ' The value of attribute heightarrow_forwardIn Public Class, create a static void method called Info_AHW that takes 3 parameters - an int and two double. When the method is called, we pass along the age (A), then the height (H), and then the weight (W), which is used inside the method to print the person's age, then the height and then the weight. NOTE: The Print out must follow the output below Afterward, in the main method, get the User input using the Scanner class to get the three input - the int age, the double height and the double weight. Then, call your Info_AHW method and pass your arguments (age, height, weight) into that method. Hint: When getting the int input, use -> sc.nextInt(); When getting the double input, use -> nextDouble(); Input: 5 65.5 70.2 Output: Your age is 5 ; your height is 65.5 ; and your weight is 70.2 Note: -There is a single space between every word and semicolon -There is no space at the endarrow_forward
- In Java In the Jackal class, complete the public method definition for setAge() with the integer parameter customAge. Ex: If the input is black Mia 3, then the output is: Color: black Name: Mia Age: 3arrow_forwardI have provided you with 3 interfaces (HasLegs, HasWings, and BreathesUnderwater) and a Tester class. I want you to create 6 new classes: • 2 that implement HasLegs • 2 that implement HasWings • 2 that implement BreathesUnderwater For each of the classes, you will have to implement the methods that the interface dictates. In addition, override toString so that it prints out a simple message describing what the object is. See the example output of my implementation below for an idea how to do that. The Tester class creates 3 ArrayLists, one for each interface. It also loops through each ArrayList and prints out its contents using toString and the interface methods. In between those two chunks of code, you’ll see a //TODO: comment. It is there that I want you to create one object for each of the 6 classes you created and add that object to the appropriate ArrayList. Once you have done all that, you should be able to run your program and see output like the following: I am a table. I have…arrow_forwardIN C++ 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. Provide another parameterized constructor which takes both efficiency and fuel as parameters. Also supply methods getGasInTank, returning the current amount of gasoline in the fuel tank. getEfficiency() return the efficiency of car. setGasInTank(double fuel), to add gasoline to the fuel tank. setEfficiency(double efficiency) Supply a method Drive () that simulates driving the car for a certain distance, reducing the amount of gasoline in the fuel tank according to its efficiency. Sample usage: Car myHybrid (50); // 50 miles per gallon myHybrid.addGas(20); // Tank 20 gallons myHybrid.Drive(100); // Drive 100 miles double gasLeft = myHybrid.getGasInTank(); // Get gas remaining in tank Supply a main method that tests…arrow_forward
- Fill in the parameters in the second method header for the overloaded method printCourse(). The number, type, and order of the method parameters are indicated in the method call from main().

Three private instance variables: radius (of the type double), color (of thetype String), and area (of type double).b. Two constructors - a default constructor with no argument (default value of radiusis 2.0, and color is Green) and a parameterized constructor, which initializes onlythe radius and the color variables.c. Getter and setter for the radius and color variables.d. Two public methods: calculateArea(), and getPerimeter, which return the areaand perimeter of a circle instance, respectively. Both methods have return.Then write a driver class that tests the Circle class. In the driver class, create two objectsof Circle class, one that tests the default constructor of the Circle class (here no user inputis required) and then get the color, radius, area, and perimeter of that object and displaythem. The second object should test the parameterized constructor (here you need to ask userto give you input to initialize the class variables).…arrow_forward
