Java Inheritance and Types

Hello,
I have some super/sub classes, listed as follows:
UnitMgr
SpecialUnitMgr (child of UnitMgr)
Unit
SpecialUnit (child of Unit)
I'm designing a lot inventory system where my SpecialUnitMgr applet will have many instances of Unit. Right now I have the system set up so that UnitMgr contains an instance var declared as "Unit aUnit;". UnitMgr as a parent class, takes care of common code between the many different UnitMgr child classes.
Right now I have SpecialUnitMgr setup to use the inherited parent/super variable aUnit, and I have extended the functionality of Unit with SpecialUnit (added more instance vars, etc). I wish to use extended features of SpecialUnit within my SpecialUnitMgr class, but I am unable to do so because of type conflicts (i.e. i cant access SpecialUnit vars or methods from the instance aUnit because it is declared as Unit in UnitMgr).
I want to keep a single instance of Unit or SpecialUnit going, but I'm not sure how to do so.
I am wondering how to get around this problem, do I use Reflection? Is my design bad? I am trying to maintain the super classes as a core package.
Jeff

If I understand the problem correctly, you want generics. public class UnitMgr<U extends Unit>
protected U aUnit;
public class SpecialUnitMgr extends UnitMgr<SpecialUnit>
}See http://java.sun.com/j2se/1.5.0/docs/guide/language/generics.html for more on generics.

Inheritance and byte-code...

My coworker and I were having a discussion today that I imagine someone here will be able to resolve for us: we were talking about how wonderful inheritance is (when used properly, of course), and the issue of the compiled byte-code came up.
Basically, it was my conclusion that a subclass contains only the byte code that differentiates it from the superclass; in other words, if a superclass is modified and recompiled, there is no need to recompile the subclass for the changes to take effect. My coworker disagreed, however, arguing that there would be linking problems between the two classes if the subclass was not recompiled (sign of an old assembly programmer, if you ask me).
Anyone know the answer to this?

I created a trivial Parent class and extended it with an
even more trivial Child class. I compiled both classes
and then made a change to the Parent class. After
compiling the Parent class only, the change took effect
in the Child class. This indicates that you are right and
your co-worker is wrong. Here are the classes if you
would like to show him.
import java.awt.*;
public class Parent
     Dimension d;
     Parent() {
          d = new Dimension(333, 777);
     public Dimension getDimension() { return d; }
import java.awt.*;
public class Child extends Parent
     Dimension d;
     public Child() {
          d = getDimension();
          System.out.println(d.height + " " + d.width);
     public static void main(String[] args) {
          new Child();

Here's how you put it into recovery mode
1: Turn off your iPHone by holding the sleep/wake button till it says "Slide to power off."
2: Hold down the home button (Button on the bottom of the display with a square in the middle) and connect it to the computer while still holding it down till you see a music note with an arrow pointing towards it appear on the screen of your iPhone
3: iTunes will give you a message, "iTunes has detected a device in recovery mode; you must restore this device to factory settings to use this device."
4: Click on "Restore iPHone."

Java GUI and runtime().exec help

I have been working on a GUI that does an assortment of tasks. The final and last task is to make copies of a 3dModel conversion program and a script file that is required to make the converter run and convert. The converter and the script file are moved to a user specified directory. The user specified directory contains all of the models that will be converted. The problem is, I can't get the GUI to boot the converter with the script file. To make the converter work, you need to pass two window's cmd commands but the commands need to occur from the same directory as the converter and script file. This is what I have tried to do:
String[] commands = new String[]{"cmd ",
"/c ",
"cd ",
smdDirectory.getPath(),
"skmodel ",
"model_definition.txt "};
try{
Process child = Runtime.getRuntime().exec(commands);}
catch(IOException e){}The files have all ready copied to the correct directory. All I need is for the GUI to execute the "skmodel model_definition.txt" commands in the correct directory. What am I doing wrong?
Thanks for the help in advance.

String[] commands = new String[]{"cmd ",
"/c ",
"skmodel ",
"model_definition.txt "};
try{
Process child = Runtime.getRuntime().exec(commands, null, smdDirectory.getPath());}
catch(IOException e){}I will try that and see if I get the desired results.
EDIT:
I got it to make. Here is the code.
String[] commands = new String[]{"cmd ", "/c ", "skmodel",     "model_definition.txt "};
     try{
          Runtime runtime = Runtime.getRuntime();
          Process child = runtime.exec(commands, null, smdDirectory);

PDA and data synchronization -help required

Hi,
I have experince in developing web applications in jsp/servlets and php. I wish to develop a PDA supported java server
application. I have downloaded netbeans for using as an IDE. It does have support for mobile emulators, but does not support
PDA/Palm OS emulators.
What about IBM websphere and eclipse for using as IDE? Will they support J2ME SDK? Please help me in devoloping my PDA
application.
why we use data synchronisation for laptop and PDA for web applications? Why is it not applied in normal PC?
Thanking in advance,
From,
Vinod

Vinod, you might want to look at the palm.com web site. There is quite alot of information available for developers.
By reading your original query, I assume you are talking about thread safety and not synchronization, per se. Thread safety is very important in a web app as you surely know. If you don't and have been developing Servlets/JSPs then, hoo boy!

Mapping data model to java classes and Interface.

Need help in mappning my data model into java classes;
Here are some of the details:
Table, Poll:
PollID int
PollName varchar
BusinessUnit varchar
DisplaySchemeID int // reference to DisplayScheme table.
Table, DisplayScheme
DisplaySchemeID
DisplaySchemeName
etc
Table, URL
UrlID
UrlName
UrlDesc
Table, PollURL
PollURLID
PollID
UrlID
PublishDate
etc
Table, Tag
TagID
TagName
PollID
So, a POLL is associate with a DisplayScheme.
A Poll can have many URLs and a URL can be associate with many Polls , mapped in the PollURL table.
and same is the situation with tags.
Essentially I want to learn how to do one to many mappning and many to many mapping.
Also to add, since I plan to use Ibatis for OR mapping.
So I should a Parameter call to map for creaint a Poll. And to create a poll the form submitted will have:
- PollName
- URLs ( multiple )
- one display scheme.
- Tags ( many )
So if you can show how to write a DAO createPoll method, then it would be great.
Not sure if am asking a lot, but this would be a great example to move forward.

The below is the sample DAO Class.
For your case, you have to create your own PollBean with getters and setters and just pass the object to the method
public int create(Connection con, ProjectBean projectBean) throws SQLException {
          int result = 0;
          String insertQuery = " INSERT INTO" +
                    " M_PROJECT(" +
                    " PROJECT_ID," +
                    " PROJECT_NAME," +
                    " PROJECT_DESCRIPTION) " +
                    " VALUES(?,?,?,?)";
          initPrepareStmt(con, insertQuery);
          setString(projectBean.getProjectID());
          setString(projectBean.getProjectName());
          if(projectBean.getProjectDescription().equals("")){
               setString(" ");
          }else{
               setString(projectBean.getProjectDescription());
          result = executeUpdate();
     return result;
     }

Inheritance and Interface invocation Query

interface IProduct{
     void getProductName();
abstract class Option implements Product{
             void exercisePrice();
             void premiumPaid();
class Option1 extends Option{
           // Implement all abstract methods defined in Option and IProduct.
class Option2 extends Option{
     // Implement all abstract methods defined in Option and IProduct.
class Trade{
           public Trade(IProduct p){
     p.getProductName()   // I can only get this method behaviour.
                // My Query
                // I also need to invoke the methods exercisePrice() and premiumPaid() defined in Option1 and Option2
                // If I use instanceof,the code will get cluttered and ugly.
                                 if p instanceof Option1
                                 Option1 op1 = ((Option1) p);
                                 op1.exercisePrice();
                                  if p instanceof Option2
                                  if p instanceof OptionN
class TestHarness{
         public static void main(String args[]){
         // Create an option
         Option1 option1 = new Option1();
         // Trade in the product
         Trade trade = new Trade(option1);
         Query:
         The Trade constructor defines IProduct.
         IProduct can be a concrete Bond,Option,CDS,IRS etc.
         How do I get the methods defined in subclasses Option1 and Option2 or for any concrete subclass of IProduct?
         Is there a way of dynamically invoking the methods of the object created?
        Or do I need to change the design.
}

It looks to me like you're violating the Liskov Substitution Principle.
"The LSP says that the users of base classes should not have to do anything special in order to use derivatives."
- R. MartinThis also violates the Open/Closed principle, because whenever you add a new Option concrete class, you're going to have to update your Trade class (it's not "closed to modification" when the environment around it changes).
The "fix" is just that its not a good idea to force the polymorphism by using instanceof. You should either:
1. Get rid of the IProduct interface completely and treat each product type separately.
2. Reconsider your base class (in this case, IProduct) to see if it really can contain additional behavior applicable to all products.
The previous post about the visitor pattern is interesting, but I don't see how it applies to this example (perhaps some more light could be shed there by the poster).

Re: Java Images and Threads prob Help!!

Without going through it in detail the problem may be that you're doing the repaint which you hope will draw the image before the image has completed loading.
Create your ImageIcon (loading the "xxxx.jpeg" files) during program initialisation. And check the load status of the icon, at least in a test version.

I still cant get the reqd output. Only the 1st image is dispayed and when i click the second code, the 2nd image doesnt come(the first one does not disappear, and even when i click the code 1 i have to minimize/ maximize the screen, to get the image and after that it does not go for the s2nd image 2 come!! )
Create your ImageIcon (loading the "xxxx.jpeg" files) during program >>initialisation. And check the load status of the icon, at least in a test version. How do u load the image during initialization??? and can ny1 plz tell me how to get the flashing threads with msgs????

Blue Screen and Error code help

I got up for a few moments then come back to see my computer Blue Screened, first time ever for me. Its running win XP and is roughly 1 1\2 years old and i have no idea what even caused the blue screen much less how to fix it so it wont happen again
The error code
c:\DOCUME~1\0\Owner\Locals~1\Temp\WER309f.dir00\Mini072409-01.dmp
c:\DOCUME~1\0\Owner\Locals~1\Temp\WER309f.dir00\sysdata.xml
BCCode 10000007e
BCP1 C00000005
BCP2 000000000
BCP3 EDEDDBB8
BCP4 EDEDD8B4
OSVer 5_1_2600
SP 2_0
Product 256_1

Not 100% sure without looking at it honestly. If it happens again I would take it in to your local store for a diagnostic.

User exit code - help required

Hi Experts,
I need to write a user exit for the field Posting level in the query. The logic is ,when posting level is either 10 or 20 for an ITEM then Key figure "Period value GC" should be divided by two and the result shouls be stored in the same Key figure.
Technical names of the fields are as follows:
Posting Level - 0cs_plevel . We have created a user exit variable ZBSUSER.
Item - 0ITEM
Period Value GC - 0cs_per_gc.
Please let me know the code to be written in CMOD to achieve the above result.
Thanks,
Kavitha Jagannath

Hi,
I need to write a user exit for the field Posting level in the query. The logic is ,when posting level is either 10 or 20 for an ITEM then Key figure "Period value GC" should be divided by two and the result shouls be stored in the same Key figure.
You can do it in report it self you don't need EXIT CODE.
Steps:
1. Create a RKF and restrict (Include)ITEM = 10 and 20 & drag and dropn Period value GC " RKF -1
2. Create another RKF and EXCLUDE ITEM = 10 and 20 & drag and dropn Period value GC. " RKF -2
3. In Columns display both and create Formula-1 and divide RKF-1 with 2.
4. Create a Formula and add Formula-1 and RKF -2
5. Hide unwanted calculations
Your problem is resloved.
Thanks

Inheritance and super usage help

so i have a parent class called Gun and i have a protected field called bulletsInGun in the constructor and then i have a a subclass called HandGun that inherits from the Gun class and i am trying to used the field bulletsInGun in the parents class constructor for the HandGun subclass constructor. how would i do that? i tried super.bulletsInGun and i tried super(bulletsInGun) and none of them work i keep getting "not a statement error".

this is my gun class the parent class

About Inheritance and interface!

I have to write a PQueue2 class which implements PriorityQueue interface, also PQueue2 has to extend BinaryHeap,
so at the top of the PQueue2 I should have this right?
public class PQueue2 extend BinaryHeap implements PriorityQueue {

I meant that if PQueue2 extends BinaryHeap
then it can call directly all the functions in the
e BinaryHeap right? but it can also add new methods?It's more like the public and protected methods in BinaryHeap are also the methods of PQueue2. If I create a PQueue2 outside of either class, I can call any public method defined in BinaryHeap on PQueue2.
the extends keyword creates an "is a" relationship between a class and the class it extends. Every PQueue2 instance is an instance of BinaryHeap (but not the other way around.)
