Chapter 5.1, Problem 5STQ
Revise the definition of the method writeOutput in Listing 5.3, using the keyword this. Do not change the meaning of the definition at all. You will just write it slightly differently. (Hint: All you need to do is add this and dots in certain places.)

Give a brief explanation of a method before going through its three main parts.
Write a note on the method with parameter and without return type. Give an
example.
2. Write a class Comparisons whose main method tests your largest method above. • First prompt the user for and read in three strings, use your largest method to find the largest of the three strings, and print it out. (It’s easiest to put the call to largest directly in the call to println.) Note that since largest is a static method, you will call it through its class name, e.g., Compare3.largest(val1, val2, val3). • Add code to also prompt the user for three integers and try to use your largest method to find the largest of the three integers. Does this work? If it does, it’s thanks to autoboxing which is Java’s automatic conversion of ints to Integers.

- You are responsible for adding the appropriate testing code to your main. a. The getValedictorian method returns the valedictorian of the class, that is the student with the highest grade point average. Implement this new method. b. The getHonorsPercent method returns the percentage of students in the class who are in the honors program. Use 3.75 as the cutoff GPA. Implement this method. Also print the list of students, by using the isHonor method, in the Honors program. c. An alternate implementation for the School class is being considered, in which the students are stored in an ArrayList instead of an array. Show how the declaration of the data field students would look in this alternate design. MAIN CLASS: import java.util.ArrayList; public class Main { public static void main(String[] args) { System.out.println("Unit07Project2 by Your Name"); System.out.println(); int size = 10; School onw = new School(size); /* Add the code…arrow_forwardThe following code is poorly structured. Rewrite it so that it has a better structure and avoids redundancy. To help eliminate redundancy, convert the code into a method named spending that accepts two parameters: a Scanner for the console, and a String for a single person's name, and prints the appropriate information about that person's bills. Your method could be called twice (once for John and once for Jane) to replicate the original code's behavior.arrow_forwardCopy your previous class definition for RectangularSolid from the previous problem, including both methods. Provide mutators (setters) and accessors (getters) for each of the three parameters. Use the naming convention for these methods that is demonstrated in your textbook (i.e. do not use the property function or decorators). These methods should allow a program using your code to modify the parameter values after creation and to read individual parameter values.arrow_forward
- Read the class Person to store the name a person we discuss in the class (source is Person.java attached in the assignment). As we can see that the methods we included merely set the name and print the name of a person. Redefine the class person so that, in addition to what existing Class does, you can Set the last name only. Set the first name only. Set the middle name. Check whether a given last name is the same as the last name of this person. Check whether a give first name is the same as the first name of this person. Check whether a given middle name is the same as the middle name of this person. Add the method equals that returns true if two objects contains the same first and last name. Add the method makeCopy that copies the instance of variables of a Person object into another Person object. Add the method getCopy that creates and returns the address of the object, which is a copy of another Person Object. Write the definition of the methods of the class Person to implement…arrow_forwardRedefine 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.

- Take a look at the header of the method below, and then implement a sample call to it in your code.empty public ShowValue ()arrow_forwardCan someone help in java Create a class Hotel with member data, hotel name and category (number of stars).For the Hotel class, write the standard methods (constructors, get & set, toString ()) and the getWiFi () method, which returns the wifi address formed by the first 4 letters of the hotel name and any number (you can get it with the random number generator) .In main (), illustrate the use of the Hotel class. Create a PopulatedHotel class, successor to the Hotel with an additional ArrayList <> field on behalf of the hotel guests.For the PopulatedHotel class, write standard methods (constructors, get & set, toString ()), with the get and set methods working with separate elements of ArrayList <>. For the PopulatedHotel class, also write methods for adding and removing a guest and a method for checking that a person is staying at the hotel. In main (), illustrate the use of the PopulatedHotel class.arrow_forwardThis solution is unclear and does not answer my question. I am trying to add a main method to my code.arrow_forward
- You are to implement removeHead, and removeTail and you also have to create the following functions (for visual purposes of the detail explanation, header and trailer sentinels are described as h and t respectively): IMPORTANT NOTE: For all the methods that has the pos parameter i.e. addAt, removeAt, move, make sure to access that specified position from whichever is nearer - the head or the tail - similar to what we have done in the get method. Example DoublyLinkedList: h <-> 10 <-> 30 <-> 40 <-> 50 <-> t int add(int num) This will add the element num into the last element of the linked list and return the position of the newly-added element. In the above example, having add(60) will return 5 as it is the fifth position in the list. int remove(int num) This will remove the first instance of the element and return the position of the removed element. In the above example, having remove(40) will return 3 as 40 was the third element in the linked list…arrow_forwardHi, this isn't the static method of doing this. Could you please do the static method?arrow_forwardThe obvious next step is to name the stars and planets using random numbers. Names usually follow certain rules rather than being made up of random strings of characters. Choose a set of real-world names (for example, from J.R.R. Tolkien's world) and create a set of rules for them to follow. Create and implement a method for generating new names based on a set of rules and random numbers.arrow_forward
