Month Class With Constructors And Getter / Setter Methods To Access Attributes

Jul 22, 2014

Write a class Month that represents one of the twelve months of the year. It should have three attributes for

the name of the month,

the number of days in the month, and

the birthstone.

Also add constructors and getter/setter methods to access the attributes.

You may use the following code to test your class.

Java Code:

import java.util.*;
public class Month
{
// ADD CODE HERE!!!
public static void main(String[] args)
{
Month[] months = new Month[12];

[Code] ....

So what I have added so far is (under public class month { :)

Java Code:

String monthName, monthBirthStone;
int monthDays;
public Month (String name, int days, String birthstone)
{
monthName = name;
monthBirthStone=birthstone;
monthDays=days;
} mh_sh_highlight_all('java');

So I believe that is the constructor. I still do not understand several things:

What would I need the getter and setter for?

I tested it using just the above code, and using month 1 I got:

Month@5a1cfb56

This makes sense as I obviously didn't do anything in order to get it in a String format for the array. But I do not understand this still - how would I get the constructor to output a string (to then be in the array?)

Fields / Getter And Setter Methods And Constructors

Mar 12, 2015

A blood clinic has hired a team of software developers to build a custom application to track patients. The clinic needs to keep a record of each patient and his or her blood data. Ultimately, they want all of the information stored in a database. As a starting point, the development team leader informs the team that the application has to have a set of core classes that represent the “real-world” entities the program needs to deal with. As a developer on the team, your job is to build a Patient class along with a BloodData class so that each Patient contains a BloodData object. This principle is known as “composition.”

Building the Framework Begin by creating a public Java class named PatientBuilder that contains a main method. Then, in the same file, create a non-public class named Patient and another named BloodType. Save the file as PatientBuilder.java. Note: If this was a real development project, you would put each class into it’s own file and put the files in the same folder. By combining them all into one file, we avoid having to submit three separate files, making it easier to keep all your work in one place.The BloodData Class This class should hold all of the attributes to hold the data the clinic needs for a given patient’s blood. Implement the following capabilities to accomplish this objective:

• Create a field to hold a blood type. The four possible blood types are O, A,B, and AB. For this project, you can simply define the field as a String.
• Create a field to hold the Rh factor. The two possible Rh factors are + and –.For this project, you can simply define the field as a String.
• Create getter and setter methods for both fields.
• Create a default constructor that sets the fields to “O” and “+”
• Create an overloaded constructor that accepts two parameters – one for a proposed blood type, and another for a proposed Rh. The constructor
should call the set methods and pass these parameter variables in to them.The Patient Class This class should hold all of the attributes to hold the data the clinic needs for a given patient’s blood. Implement the following capabilities to accomplish this objective:
• Create a field to hold an ID number along with get and set methods.
• Create a field to hold the patient’s age along with get and set methods.
• Create a field to hold the BloodData for a Patient. When declaring the field, initialize it by instantiating a BloodData object. Create get and set methods.
• Create a default constructor that sets the ID to “0”, age to 0, blood type of the BloodData object to “O”, and Rh value of the BloodData object to “+”.
• Create an overloaded constructor that accepts the following parameters: ID,age, blood type, and Rh. The constructor should call the set methods for the field associated with each parameter.The PatientBuilder Class.This class should contain the main method from which the program runs. In that method, implement the following functionality:• Ask the user for the ID, age, blood type, and Rh factor of a Patient.
• Create a Patient object, passing all of the data obtained from the user into the object.
• Write the code necessary to display the ID, age, blood type, and Rh factor of the Patient by calling the appropriate get methods of the object.

MY CODE ( which does not compile since it is wrong...)

import java.util.Scanner;
public class PatientBuilder
{
public static void main(String[] args){
String patientID;
int patientAge;
String patientRh;
String patientBlood;

Using Setter And Getter Methods Instead Of Altering Variables

ImageIcon Setter And Getter Methods Not Working

Jan 3, 2015

I have been assigned with a task to have a class which has the methods setImage and getImage. These methods are meant to set the ImageIcon by using the url taken from another class and the getImage method is meant to return the ImageIcon that was set before hand. The problem is that i'm not really familiar with ImageIcon so the code in both my methods is giving out errors and i just can't figure out why. Heres the code in the class that has the setImage and getImage methods:

public class Die implements DieInterface {
private ImageIcon [] image = new ImageIcon[6]; //the number of images that would be stored in this array is 6 (six faces of the dice)
ublic Die()
{
//This puts images into the images array(the different die faces)
image = new ImageIcon[6];

[code]....

And this is where i call the methods (set and get methods) in the other class:

die1.setImage(new ImageIcon(Dice.class.getResource("face1.png")));
die1.getImage();

How To Access Getter Method From Different Class

Sep 16, 2014

I have 2 classes. TestClassA has 1 getter and 1 setter. From my second class, TestClassB, I want to access the getter method of TestClassA. If I try to access it, I get null. How do I do it?I do not want the methods to be declared as static. How can the getter method value be printed in TestClassB (without marking anything as static)?

public class TestA {
private String name;
public String getName() {
return name;

Possible To Set Setter And Getter Various Times

May 8, 2014

I am trying to set my setter and getter various times o that I can store a name, price and value but i can only set it once. Once i try to set again the previous entry resets.I have tried

job = sc.next();
jobdetails.setjob(job);
wage = sc.next();
wageD.setwage(wage);
hours = sc.next();
hourd.sethour(hour);

This sets the values for me and i receive the input i entered but if i try to enter again the input from before is removed.I have searched array lists and tried

[code] List<Object> list new ArrayList<Object>();
list.add(jobname)
list.add(price)
list.add(Event)

out.println(list.get(0));

for (Object s : list) {
out.println(s);
}

For this to work I would have to keep adding list.add. Is there a way I can use the array to add a new item to the list so that when I try to display what I have stored in the setter and getter it will display what I have entered in each time instead of only the last input? or any other way that may be possible to do this?

Scanner Class - Can't Seem To Access Methods

May 9, 2014

I have two classes built for this assignment. One with getters, setters and constructor and a test class. The test class works fine up until the point when the user wants to (M)odify an employee that he/she built with the loadEmployee method. What happens is I need to enter multiple "M" inputs before anything pops up, and when something pops up, it's the displayMenu instead of modifyEmployee method. I imagine it has something to do with the amount of sc.nextLine()

import java.util.Scanner; // utilize scanner via console
import java.text.NumberFormat; // allows numbers to be format in form of currency
//Example of "big loop" in main to repeat using a No Trip (0,N) test first
public class EmployeeTest {
// space provided to make code easier on eyes...

Using Accessor Methods To Access Data From Another Class

May 6, 2014

I have been asked to write a program with 3 classes(an interface, a store and a product class) and I have been going ok until I need to display data on the interface that is held in the product class. At the moment the code will compile fine but when I run the program and try to use the writeOutput() method I get a stack overflow error.

I realise now that it is because of a non-terminating recursive call, however I can not think of a solution on how to fix the problem. And just to clarify, what I am aiming to do is have the MatesTerminal class display the data for name that is stored in the Product class(I have no way of determining which product to display at this time, so I would like to be able to display the data for all three products if possible). Anyway this is what I have so far:

The method from the MatesTerminal Class:

private void writeOutput() {
int productChoice;
Scanner console = new Scanner(System.in);

Constructors In Class Hierarchy?

Feb 9, 2014

I remember reading that a super() call to parent no-argument constructor is automatically inserted by compiler. So, if i have a chained hierarchy of classes (starting at top, with Object), will there be a chain of super() calls, going from bottom to top in the chain ? Will a super() call be inserted in child, if i provide a no-argument constructor for this class ?

Write Constructors To MyStack Class

Jan 6, 2015

MyStack class have by default some fixed size of maximum elements, allow user of your class to specify in constructor what this maximum size is. Also add possibility to specify name of the stack in constructor. User can either create object without parameters, can specify only size or name, or both of them. And also override function toString(), that this code will print:

[stack1] 4 6 1
[stack2] empty
MyStack s1 = new MyStack("stack1");
MyStack s2 = new MyStack("stack2");
s1.push(4);
s1.push(6);
s1.push(1);
System.out.println(s1.toString());
System.out.println(s2.toString());

You will need in total 5 constractor: default constructor (new Stack())

1-parameter constructor precising maximum size of the stack (new Stack(10))

1-parameter constructor giving the stack name (new Stack("My Stack"))

2-parameter constructor giving the maximum size and the name of the stack (new Stack("My Stack", 10))

"copy" constructor (Stack s1=new Stack(); Stack s2=new Stack(s1);)

Creating Instance Variables And Constructors For Map Class

Mar 27, 2014

I have to create an application that deals with maps.

I first have to create the instance variables for the class.

So very simply if my hashmap is going to consist of football clubs and players. Football clubs being a string value for the key and players being a set of strings for the values. How would I go about creating the instance variable in a class for this?

I can't seem to find anything that specifically deals with instance variables and constructors for maps.

Declaring Methods For A Class In Its Own Class Whilst Objects Of Class Declared Elsewhere?

Mar 5, 2015

How do you declare methods for a class within the class whilst objects of the class are declared else where?

Say for instance, I have a main class Wall, and another class called Clock, and because they are both GUI based, I want to put a Clock on the Wall, so I have declared an instance object of Clock in the Wall class (Wall extends JFrame, and Clock extends JPanel).

I now want to have methods such as setClock, resetClock in the Clock class, but im having trouble in being able to refer to the Clock object thats been declared in the Wall class.

Is this possible? Or am I trying to do something thats not possible? Or maybe I've missed something really obvious?
