Implements interface method at the derived class

Hi all.
I have a class (Derived) that extends another class (Base).
In the base class (Base) there is a method f() with its implementation.
In the interface (C) there is also f() method exactlly like in the base class (Base).
The derived class (Derived) is implements the interface (C).
My question is:
Do i have to implement the method f() in the derived class (Derived) ?

My guess is that you probably have to, even if it's just to call the parent's method.
This all sounds pretty sketchy. Why don't you just make the BASE class implement your interface?

Implementation of the hasProperties() method of the Node class

The following snippet of code prints:
false
true
which seems to be a bug.
TextField nameField = new TextField();
System.out.println(nameField.hasProperties());
ObservableMap<Object, Object> props = nameField.getProperties();
System.out.println(nameField.hasProperties());The implementation of the hasProperties() method in the Node class returns true, if the ObservableMap object for storing properties has been created. That is not what is expected from this method. I think, this method should also check if the ObservableMap has any properties.
Can someone confirm that it is a bug?
Thanks
Kishori

You can log it at http://javafx-jira.kenai.com and then, if the developers want to keep it the way it is (which they may for API compatibility purposes), they can at least document it so that a user would know what to expect without writing a test or making a potentially invalid assumption.

Getting Bad Type Error when calling a method in the proxy class

Overloaded methods in a derived class

Hello to everyone. I'm starting to learn java with the help of "Thinking in Java". I just want something to make it clearer for me.
Suppose I have a base class with a method, and a derived class which overloads the method:
class Base {
void method() {
    System.out.println("Base method");
class Derived extends Base {
void method() {
    System.out.println("Derived method");
}Now, in another class somewhere I create an instance of Derived:
Derived dv = new Derived();
dv.method();There is no way that I can access the method from the Base class, right? The only way I can do that is through
class Derived extends Base {
void method() {
    super();
    System.out.println("Derived method");
}As I said, I'm almost sure that this is correct, I just want a confirmation.

You can change the class
class Derived extends Base {
void method() {
    super.method();
    System.out.println("Derived method");
// calls Base.method()
void baseMethod() {
    super.method();
}

Accessing a private variable from a public method of the same class

can anyone please tell me how to access a private variable, declared in a private method from a public method of the same class?
here is the code, i'm trying to get the variable int[][][] grids.
public static int[][] generateS(boolean[][] constraints)
private static int[][][] sudokuGrids()
    int[][][] grids; // array of arrays!
    grids = new int[][][]
    {

Are you sure that you want to have everything static here? You're possibly throwing away all the object-oriented goodness that java has to offer.
Anyway, it seems to me that you can't get to that variable because it is buried within a method -- think scoping rules. I think that if you want to get at that variable your program design may be under the weather and may benefit from a significant refactoring in an OOP-manner.
If you need more specific help, then ask away, but give us more information please about what you are trying to accomplish here and how you want to do this. Good luck.

Passing values between methods in the same class

Hi,
How to pass internal tables or values between methods in the same class.
How to check if the internal method in another method is initial or not.
How to see if the method has already been executed.
Thanks.

Just declare the internal table as an attribute in the class - that way every method in this class has access to it.
Since any method has access to all class attributes you can easily check if the internal table is initial or not.
I am not aware of any standard functionality if a method has already been executed or not, one way would be to declare a class attribute for each method and set it once the method has been executed. That way every method in that class would know which method has already been executed or not.
Hope that helps,
Michael

What does the trim() method of the String class do in special cases?

Looking here ( String (Java Platform SE 7 ) ), I understand that the trim() method of the String class "returns a copy of the string, with leading and trailing whitespace omitted", but I don't understand what the last special case involving Unicode characters is exactly.
Looking here ( List of Unicode characters - Wikipedia, the free encyclopedia ), I see that U+0020 is a space character, and I also see the characters that follow the space character (such as the exclamation mark character).
So, I decided to write a small code sample to try and replicate the behaviour that I quoted (from the API documentation of the trim method) in the multi-line comment of this same code sample. Here is the code sample.:
public class TrimTester {
    public static void main(String[] args) {
         * "Otherwise, let k be the index of the first character in the string whose code
         * is greater than '\u0020', and let m be the index of the last character in the
         * string whose code is greater than '\u0020'. A new String object is created,
         * representing the substring of this string that begins with the character at
         * index k and ends with the character at index m-that is, the result of
         * this.substring(k, m+1)."
        String str = "aa!Hello$bb";
        System.out.println(str.trim());
However, what is printed is "aa!Hello$bb" (without the quotes) instead of "!Hello$" (without the quotes).
Any input to help me better understand what is going on would be greatly appreciated!

That's not what I was thinking; I was thinking about the special case where the are characters in the String whose Unicode codes are greater than \u0020.
In other words, I was trying to trigger what the following quote talks about.:
Otherwise, let k be the index of the first character in the string whose code is greater than '\u0020', and let m be the index of the last character in the string whose code is greater than '\u0020'. A new String object is created, representing the substring of this string that begins with the character at index k and ends with the character at index m-that is, the result of this.substring(k, m+1).
Basically, shouldn't the String returned be the String that is returned by the String class' substring(3,9+1) method (because the '!' and '$' characters have a Unicode code greater than \u0020)?
It seems to not be the case, but why?

Are methods in the Graphics class Thread Safe

Can methods from the Graphics class (.e.g. drawImage(), drawString(), ect..) be called from any thread? In other words, can two threads that refer to the same Graphics object step on each other methods calls?
TIA,
DB
Edited by: Darth_Bane on Apr 27, 2009 1:44 PM

No,
They are GUI activities so you should call them from the Swing Thread ( Event Disptach Thread)
Now for the JComponent the following are thread safe:
repaint(), revalidate, invalidate which can be called from any thread.
Also the listener list can be modified from any thread addListenerXX or removeListenerXX where XX is ListenerType

When do we override our own clone method not the Object class clone method

Hi,
I have a confusion in overriding clone method.We can create clone object by writing Object.clone() but some times I have seen writing our own clone method ,when do we write this,also clone() is defined protected and when we write our own clone it is said to write it public,why?
Thanks
Sumit

protected methods can only be called in the same class and it subclass. You can make clone protected if this is all you need.
However if you need to clone() the object from another class, it need to be public.
This is the same for any method.
Also as Object.clone() is protected you cannot make it private or package-local (this is true of any protected method)

Method is called in the superclass, instead of the derived class

Hello,
I have created a FI workflow for releasing invoices, and a BO called ZSF1FIPP that is derived from FIPP. in ZSF1FIPP I had defined all the methods needed for the workflow, like GET LEVEL.
In all the workflow tasks, the object assigned is ZSF1FIPP.
When I test run the workflow, I get an error like, straight in the first task:
'Method GET LEVEL is not implemented in FIPP'.
That is very puzzling.
The WF was transported from another system, and activated without error in the new system. I have deleted and then recreated the ZSF1FIPP object, with the same result in workflow. If I test the object alone, it works without a glitch.
If you have any clue about this, please advise.
Regards,
Adrian

Hello,
Thx for answering to my question.
In swo1 I have enterd FIPP and then the button subclass. Then I had filled all the details requested by sap, and created the ZSF1FIPP subclass.
If I ciick the general details button, I cand see FIPP as super class.
Do I have to do some thing else also, to activate the link ?

I have this issue that I am trying to deal with. It looks pretty simple to me, but maybe just a mental block I guess :)
Now the code below will give you an idea of what I am trying to achieve. I am not sure if its possible or if there is some other better way to do this. Any help will be appreciated.
Thanks
public class TestClass extends Thread{
     public TestClass(){
     // Assume something goes in here.

          System.out.println("In xyz");

     //What do I put here, since my call is specific.
     public static void main(String args[]){

you can use the Reflection API to make the desired method an instance variable:Whoa, that's a pretty big case of over-engineering (or under-engineering, depending on how you look at it) and abuse of Reflection. The real problem in the original post is that Thread isn't being used properly. You almost never want to subclass Thread, for reasons like these: your runnable target should be separate from the thread. I would organize your code like this:
public class TestClass {
   public TestClass() {
      // Assume something goes in here.
   public void abc() {
      System.out.println("In abc");
   public void xyz() {
      System.out.println("In xyz");
   public static void main(String args[]) {
      final TestClass t1 = new TestClass();
      final TestClass t2 = new TestClass();
      new Thread(new Runnable() {
         public void run() { t1.abc(); }
      }, "t1Thread").start();
      new Thread(new Runnable() {
         public void run() { t2.xyz(); }
      }, "t2Thread").start();
   }

How does a method extend another method in the same class ??

hi everybody, I want to know if it is possible to have such code as:
void foo(){
// foo process
void bar <<extend>> foo{
//foo process
//bar process
thanks for helping me

Since you want different names for each of your so-called "child" methods, then neither overloading nor overriding in a subclass will work as each relies on the same method names. Perhaps the following will suffice:
public class MyClass
   //some stuff
   private myMethodThatDoesSomeStuff()
      //do some stuff that all the other methods must also do
   private methodA(int q, byte z)
      myMethodThatDoesSomeStuff();
      // continue with this method.
   private methodL(short v, float g23)
      myMethodThatDoesSomeStuff();
      // continue with this method.
}If not, you need to do some design work.

Get method in the Attribute class. in JNDI

I had connected to the AD
// Create the initial directory context
DirContext ctx = new InitialDirContext(env);
Attributes attrs = ctx.getAttribute("DC=DomainDnsZones,DC=testing,DC=local");
but I had no idea wat to get from the attrs.get method.
as in, I don't know what kind of attributes ID are available inside my attrs
is there any coding to get all the attribute ID so tat I can use the get method to retrieve them?

We can get the available Attributes for a particular user.....
using Attributes class for a Search and Context....
You can try out the free LDAP viewer available in internet (Its a Applet)... u can find the possible Attribute Names in that... and use the below statement..
Attributes attrs1 = ctx.getAttributes("CN=" + "user,CN=Users,DC=domain,DC=dmn,DC=com");
String office = (String)attrs1.get("physicaldeliveryofficename").get();

Why uses the methods in the InputProcessorSupport class

Hi, there
InputProcessorSupport provides some methods you can use to set/retrieve the
name/value to the session scope or request scope. But what are the
differences between them and the traditional Request.setAttribute() and
Session.setAttribute() method? What are the advantages of using these new
API?
Thanks
