Classes and object exercise! help!

I'm really really new to JAVA... don't even know how to make a single line of code that will run.
I have this exercise that wants me to.... creat a MySavings application that displays a menur of choices for entering pennies nickels, dimes and quarters... it tells the user to make a selection.... The application should include a PiggyBank object that can add coins to the piggy bank, remove coins, and return the total amount in the bank. The output looks like this:
*1. show total in bank.*
*2. Add a penny.*
*3. add a nickel*
*4. add a dime.*
*5. add a quarter*
*6. take money out of bank.*
Enter 0 to quit.
Enter your choice: 5
yea.....can someone start me off? Because I have no idea where to start, or how to write this program.
I only know that it will begin like:
public class MySavins {
please help. thanks in advance!

Dx I usually I understand it when the code is given... i'll analyze it and be like 'ohh thats how u do it" and understand it when theres an example.I'm sure there are examples in your text or tutorial or presented by your teacher, as there are in the links I provided. And you can google for examples of I/O, computation, looping, whatever concept is giving you trouble.
The first thing you have to do though is break the problem into pieces and figure out the steps for the different pieces without regard to Java.
Im new to this school taking comp sci so Ive never learned this program from the beginning... and this course starts from chap 10. for my grade.That's irrelevant and doesn't change anything I've said.

  • Need help w/ created classes and objects

    I am having a difficult time understanding what is wrong w/ my classes and objects. I've looked in two books and have messed around a bit. Here is what I am -attempting- to do.
    I want to make a class called CLOTHING. In this class i want objects such as shirt and pants (for now).
    these are the errors im getting:
    .\Shirt.java:6: invalid method declaration; return type required
         public Shirt(int size){
                   ^
    .\Shirt.java:3: class Clothing is public, should be declared in a file named Clothing.java
    public class Clothing {
           ^
    MyClassHW.java:10: cannot resolve symbol
    symbol  : constructor Shirt  (int,int)
    location: class Shirt
              myShirt = new Shirt(1,1);
                              ^
    3 errors------------------------------------------------------------
    This is the code for my Clothing class:
    import java.awt.*;
    public class Clothing {
         private int shirtSize;
         private void Shirt(Graphics s, int h, int v){
         Polygon shirts;
              shirts = new Polygon();
              shirts.addPoint(5+h,8+v); // 1
              shirts.addPoint(17+h,12+v); // 2
              shirts.addPoint(19+h,13+v); // 3
              shirts.addPoint(33+h,8+v); // 4
              shirts.addPoint(37+h,13+v); // 5
              shirts.addPoint(25+h,20+v); // 6
              shirts.addPoint(25+h,28+v); // 7
              shirts.addPoint(15+h,28+v); // 8
              shirts.addPoint(15+h,20+v); // 9
              shirts.addPoint(1+h,12+v); //10
              s.fillPolygon(shirts);
    }from what i understand each object is essentially a method...
    Here is the code for the java applet I'm making:
    import java.awt.event.*;
    import java.awt.*;
    import java.applet.*;
    public class MyClassHW extends Applet { // implements ActionListener, AdjustmentListener {
         Shirt myShirt;
         int size;
         public void init(){
              myShirt = new Shirt(1,1);
    // <applet code = "MyClassHW.class" height = 300 width=300> </applet>thank you for your time and help. as always, your efforts are appriciated.

    .\Shirt.java:6: invalid method declaration; return type required     public Shirt(int size){
    I guess, public Shirt(int size) is constructor in class shirt. You have one int in this constructor. Shirt(int size)
    Here you initialize your shirt with two int:
    MyClassHW.java:10: cannot resolve symbolsymbol : constructor Shirt (int,int)location: class Shirt          myShirt = new Shirt(1,1);
    Shirt(int size, int what?)
    It's why it show such message.
    But even if you fix it seems like you have very vague ideas about what you are doing.
    As far as I understood you need three classes.
    First applet Clothing:
    public class Clothing extends Applet{
    Shirt myShirt;
    Pants myPants;
    public void init() {
    myShirt = new Shirt(1); // small shirt
    myPants = new Pants(32, 40); // medium waist and long legs
    Second and third your classes Shirt and Pants:
    public class Shirt extends Object {
    int size;
    public Shirt(int s) {
    size = s;
    public int getSize () {
    return size;
    same for Pants, only you need two parameters for it or whatever you want.
    You could design it diffrently if you want derive your Shirts and Pants from Clothing and then to use them in your applet. But, indeeed, you desperately have to do some serious reading, where authors are accurate in they definitions and stuff, because it's kind of complicated.

  • Class and Object name change in the universe designer

    Hello Experts
    I have a confusion , I am just wondering if I devlop a bobj universe, lets say, based on SQL database and change the name of the class and object during the creation of the universe, will that fetch the data from d/base properly while running a query / report. Although universe class and object has different names than database now but the records are the same. Do we need to point the object to d/base object in some kind of different or special way .
    To make my question more simple, In d/base table name is "Employee" whereas on universe side I create a class name "Staff" and at the same time field name in the database is "Emploee ID" whereas in the universe I named it "Badge number".
    Please advise if that will make any difference while I run the query or Is there any kind of complication on the universe side that I should expect which I am not familiar with.
    I would apprecite your response.
    Best Regards

    Hello experts,
    Let me rephrase the issue with exact scenario.
    I have a table names "REGION" with fields region id, region and country id.
    I have another table name REGION_SLINE with fields SL_id, region id and Sales_revenue.
    I created an equi join between these two tables based on region id field and checked the cardinality which is ok.
    Now when I try to create a report based on sales revenue per customer ( "customer's first name"  is an other field on CUSTOMER table), I dont get any result in the report and get a message that "No data to reterive"
    Also please note that when I run a report which is sales revenue per region id, I get the result, seem slike these two tables REGION and REGION_SLINE can generate the report but sales revenue per customer report is not generated because customer first name is a field of another table.
    I was just wondering if I need to write some kind of where clause in the object properties of region id which is used to create equi joon link.
    I woulld appreciate your response.

    Yea I am. I deleted Logic Pro 9 and moved the App to the Trashcan like normal. Then when I go to install it, it says its already Installed. When I do this with other apps; it works fine, the install thing comes back up like it should once you have deleted the app

  • Can I use classes and objects to create my own package in LabVIEW?

    Hi....I am writing my thesis on develpoing a simulation package.  I am trying to compare simulation packages and their feautures as a scope of my project.  Does anyone know if LabVIEW allows users to create their own toolboxes like MATLAB?...i mean something that can be done in object-oriented programming by making classes and objects.
    thanks guys 

    The short answer is yes. NI sells toolkits. There's also OpenG. How you code the guts is up to you - you can do it non-LVOOP or LVOOP.

    The Java Tutotials has several trails that discuss both implicit and explicit locking, how they work and has code examples.

  • MAT error: 0xHEX is used a class and object...

    Hi there,
    playing around some more with MAT I ran into the following error with some of my dumps. All were taken on 1.5 SUN JVMs (running on either Solaris or Linux).
    org.eclipse.mat.snapshot.SnapshotException: Error: 0x8d776450 is used as class and object simultaneously. Are you using a beta DLL for Sun JDK 1.4.2 to write the heap dump?

    jmap -heap:format=b <pid>
    Still, some work, some do not. Any suggestions?
    bye, Michael

    Hi Michael,
    this smells like a bug. The easiest way again is to have a look at the dump. If you zip it, it should become smaller. I could also provide upload space. Right now, I am at the J1 in San Francisco so it might not be as easy for me to fix this.

    i don't know why it's all null. i assign something in the default constructor. it shouldn't be "null".
    does anyone know why?

    when you create 2 class using netbean editor, person.java and test.java
    i never compile person.java.
    when i finish typing these 2 class and i just right click test.java and run.
    my question is do i need to compile person.java before i run test.java directly??
    does Netbean compile it automatically when i run test.java first time?
    i add another constructor Person constuctor with one parameter in Person.java and create 2nd object to test the 2nd constuctor and run.
    All the codes work, so does the first default constructor. i don't why is that.
    Then i removed what i added and restore back to where it didn't work before and test again. it works.
    @_@. so weird.
    problem solved. thank you

  • Classes and Objects

    I am new to object oriented programing. Now I think I am in little bit confusion with the concept of Basic building blocks of Object oriented programing. My doubt is;-
    1) "What Actually a class is ? Is it a user defined Data Type ?"
    2) "What actually an Object is ? Is an Object another format of a class ? Or an object is just a piece of Class, I mean is a group of Objects going to construct a class ?"
    3) "Is an object going to contain the reference of the data members only or both the data members and functions as well ? If It is going to contain both of these two then what is the Difference between a class and an object ?"
    4) "Is Constructor simply a function or something else ?"

    I am new to object oriented programing. Now I think I am in little bit confusion with the concept of Basic building blocks of Object oriented programing. My doubt is;-
    1) "What Actually a class is ? Is it a user defined Data Type ?"More or less. You can find a more complete definition in any text or tutorial, or with a simple google search.
    2) "What actually an Object is ? Is an Object another format of a class ? Or an object is just a piece of Class, I mean is a group of Objects going to construct a class ?"Again: text, tutorial, google, or any combination.
    3) "Is an object going to contain the reference of the data members only or both the data members and functions as well ? If It is going to contain both of these two then what is the Difference between a class and an object ?"Data only. But the object also knows what class it is and where to find its class definition that tells it what methods it has.
    4) "Is Constructor simply a function or something else ?"It's not a method. It' similar to a method, in that it's a named grouping of operations, but it doesn't have a return type, and it can only be called at certain points in your code. It's job is specifically to get a newly created object into a valid initial state.

  • Which of this is true about class and object?

    (a) A class is made of objects
    (b) A class is a collection of objects
    (c) A class supplies or delivers objects to the rest of the application
    (d) A class is used as a template to create objects
    (e) An object inherits its variables and their values from its class
    (f) An object inherits its variables and methods from its class
    (g) An object inherits its variables and methods from its class and its superclasses
    (h) The variables and methods of a class are defined in its objects
    (i) The variables and methods of an object are defined in its class
    (j) The variables, variable values and methods of an object are given in its class

    (a) A class is made of objects - true
    (b) A class is a collection of objects - true
    (c) A class supplies or delivers objects to the rest of the application - true
    (d) A class is used as a template to create objects - true
    (e) An object inherits its variables and their values from its class - false
    (f) An object inherits its variables and methods from its class - true
    A class is a not collection of objects. A class not only contains objects
    A class represents objects and others.

  • Unable to map nested java classes and objects in actionscript using flex

    Hi All..,
    Im a newbie in flex and actionscripting...,I however have a task assigned in this domain and goin insane since a week now with this problem...
    Problem explained:
    I have a class called Unit that inturn have many other classes like for example unit has an engineer class,,,Im not able to access the attributes of engineer using the unit class...that is unit.engineer,engineerid is giving me a null...however attributes unique to unit are accessible...
    Please help me out with this...,this problem has already eaten up my deadlines...
    Any help would be appreciated and thankz in advance..

    Thank you for the swift reply...,
    I actually have three java classes Unit , Engineer and UnitretrievalRemote....
    Unit contains engineer and also UnitRetrievalRemote has methods to retrieve unit which inturn should return engineer...,However i hav actionscript classes for both engineer and unit and mapped it apporopriately using the remotetag...and also my remote object is defined with a destination...
    The below code is my Actionscripting code included in mxml:
    import UnitScript.Engineer;//These are my Action Scripting Classes
    import UnitScript.Unit;
    import mx.collections.ArrayCollection;
    import mx.collections.ArrayList;
    import mx.controls.Alert;
    import mx.events.FlexEvent;
    import mx.rpc.events.ResultEvent;
    public var unitIds:ArrayCollection;//I'm passing an array from java end
    that retrieves the unitId's from the db using hibernate...
    public var index:int;
    public var unit:Unit;
    protected function initData():void
    ApplicationService.getUnitIds();
    //This is the remoteobject call using blazeds to load the method during application start from java..
    private function setUnitIds(event:ResultEvent):void
    unitIds  = ArrayCollection(event.result);
    private function setUnit(event:ResultEvent):void
    unit = Unit(event.result);
    //mx.controls.Alert.show( "Compling" );
    //mx.controls.Alert.show( "Engineer Method" +unit.engineerId);
    //mx.controls.Alert.show( " Engineer=="+unit.engineer) ;
    unitIDText.text = String( unit.unitId );
    customerName.text = unit.name;//displaying the contents fetched from the backend in the panel...
    setEngineer(event);
    private function setEngineer(event:ResultEvent):void
    unit.engineer = Engineer(event.result);
    unit = Unit(event.result);
    eng_id.text = String(unit.engineer.engineerId);
    mx.controls.Alert.show( "Engineer ID Please Show"+unit.engineer);
    //This prints a null.
    mx.controls.Alert.show( "Direct Engineer Id" +unit.engineer.category);
    // This prints a null.
    Remote object mapping is as below:
    <mx:RemoteObject
        id="ApplicationService"
        destination="Destination1" >
        <mx:method name="getUnitIds" result="setUnitIds(event)"
        fault="mx.controls.Alert.show(event.fault.faultString)"/>
        <mx:method name="getUnit" result="setUnit(event)"
        fault="mx.controls.Alert.show(event.fault.faultString)"/>
    </RemoteObject>
