Referencing a method in one class from a constructor in another?

Hi,
I'm not sure whether this is a simple question or not, but instead of rewriting the method in another class, is there a way that I can reference that method, eg:
public int getTitleCode() {
return titleCode; }within the constructor of another class. I don't want to use inheritance with this because it would change all my existing contructors.
Any ideas how to do this, or is it just simpler to add the method to both classes?
Many thanks!

Hi,
I'm trying to use a method, defined in Class A, within one of the constructors in Class B. Class B object represents a copy of the output of Class A, with the addition of a few extra methods.
Therefore to represent the details correctly in the saved text file for class B, I need to call a method from class A to save the text file for class B correctly.
Class B saves a file with a reference number unique to that class, plus a reference number that is also saved in the text file for class A.
I can achieve the correct result for the above by having the same method in both classes, but I just wondered whether instead of this I could in fact call the method from class A in the constructor for class B. With the following code,
    referenceNumber = refNum;
        titleReferenceNumber = titleRefNum;
        titleRefNum = titles.getTitleCode();
    }I just get a 'nullpointerexception' when I try to run this in the main class.
Any help or advice appreciated!

Calling a method of one class from another withing the same package

hi,
i've some problem in calling a method of one class from another class within the same package.
for eg. if in Package mypack. i'm having 2 files, f1 and f2. i would like to call a method of f2 from f1(f1 is a servlet) . i donno exactly how to instantiate the object for f2. can anybody please help me in this regard.
Thank u in advance.
Regards,
Fazli

This is what my exact problem.
i've created a bean (DataBean) to access the database. i'm having a servlet program (ShopBook). now to check some details over there in the database from the servlet i'm in need to use a method in the DataBean.
both ShopBook.java and DataBean.java lies in the package shoppack.
in ShopBook i tried to instantiate the object to DataBean as
DataBean db = new DataBean();
it shows the compiler error, unable to resolve symbol DataBean.
note:
first i compiled DataBean.java, it got compiled perfectly and the class file resides inside the shoppack.
when i'm trying to compile the ShopBook its telling this error.
hope i'm clear in explaining my problem. can u please help me?

Invoke a method in one class from a different class

I am working on a much larger project, but to keep this simple, I wrote out a little test that would convey the over all theory of the program.
What I am doing is starting out with a 2 JFrames and a Class. When the program is launched, the first JFrame opens. In this JFrame is a label and a button. When the button is clicked, the second JFrame opens. This JFrame has a textField and a button. The user puts the text in the textField and presses the button. When the button is pushed, I want the text that was just put in the textField, to be displayed in the first JFrame's label. I am trying to invoke a method in the first JFrame from the second, but nothing happens. I have also tried making the Class extend from JFrame1 and invoke it from there, but no luck. So, how do I invoke a method in a class from a different class?
JFrame1 (I omitted the layout part. I made this in Netbeans so its pretty long)
public class NewJFrame1 extends javax.swing.JFrame {
     private NewClass1 nC = new NewClass1();
     /** Creates new form NewJFrame1 */
     public NewJFrame1() {
          initComponents();
          jLabel1.setText("Chuck");
     public void setLabels()
          jLabel1.setText(nC.getName());
private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {
     NewJFrame2 j2 = new NewJFrame2();
     j2.setVisible(true);The class
public class NewClass1 {
     public static String name;
     public NewClass1()
     public NewClass1(String n)
          name = n;
     public String getName()
          return name;
     public void setName(String n)
          name = n;
}The second jFrame
private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {
     NewClass1 nC = new NewClass1();
     NewJFrame1 nF = new NewJFrame1();
     nC.setName(jTextField1.getText());
     nF.setLabels();
     System.out.println(nC.getName());At this point I am begging for help. I have been trying for days to figure this out, and I just feel like I am not getting anywhere.
Thanks

So, how do I invoke a method in a class from a different class?Demo:

     if (i == 10)
         return "ten";
     else
         return "nothing";
}Output is "ten".

Call a method of a class in a constructor of another class?

Is this good programming or should i do it in another way?
Consider an ordering system, where I have three classes, "Booking", "Table" and "Customer.
My idea is to create a booking assigned to a table and a customer, the fields in the booking class is a Customer and a Table and the constructor assigns values to these field.
In my Table class i have a method that books the table "bookTable(Customer customer)" and sets the availablility to 'false'.
So my question is, is it good programming to call the method 'bookTable()' in the table class from the constructor of the Booking class? Or should i do it in another way?
Edited by: DJHingapus on Jul 6, 2009 5:12 AM

This sounds the wrong way around. What is the return value of bookTable(Customer)?
I'd expect it to return a Booking object that it creates.
Generally, you want the constructor to do as little as possible (while still only ever returning in a valid state, of course!).
The problem you can get when you call other methods is that you introduce the possibility of other objects getting access to your object before the constructor has finished running (i.e. before the object is completely initialized). This can lead to nasty problems that are hard to find and debug.

How to call main method in one class from another class

Suppose i have a code like this
class Demo
public static void main(String args[])
System.out.println("We are in First class");
class Demo1
public static void main(String args[])
System.out.println("We are in second class");
In the above program how to call main method in demo calss from Demo1 class......???????

No, i dont know how to call other than main methods from other classes
And one more doubt i have i.e. Like in C can we see the execution of the program like how the code is being compiled step by step and how the value of the variable changes from step to step like(Add Watch).........

Can I Call method on one JVM from another through a dll?

Let me explain.
I have this java jar file that I can only have one instance of running at any given time. I'm using a shared data segment in a dll to store a bool indicating whether the program is already running or not. If it's already running, I have to not run the second instance and give focus to the current running instance.
The jar file calls a native method "canInstantiate()" on a dll to see if there's already an app running. If there isn't, the env and obj are stored in the shared data segment of the dll and we return true. If there is already an instance of the program running, I want canInstantiate call a function on the current instance of the jar (like a callback) to tell it to request focus. It's not working. Can someone tell me if my code is right?
The .h file
#include "stdafx.h"
#include <jni.h>
#include "CardServer.h"
#pragma data_seg("SHARED") // Begin the shared data segment.
static volatile bool instanceExists = false;

jdouble canInstantiate(JNIEnv *env, jobject obj);

Can I Call method on one JVM from another through a dll
...The rest of your question merely expands on your title.
And the answer to that question is no.
When you call a method you are executing a "thread of execution." A thread of execution exists only in a single process. It can not exist in another process.
If the dll is doing some interesting things then you could call a method that sets a flag. Data can move between instances. But you would then have to have a thread in that different process monitoring that flag. And sharing data in a dll is not a normal process, so it would have to be coded appropriately.
If all you want to do is set the current focus to the existing application, then that can be done with existing windows functionality. You don't need to do anything special in your dll. You can probably search these forums to find the exact code. If not there are countless examples in windows repositories (like MSDN) on how to do that.

Methods of One Class In Another

Can I make the methods of one class work in another?

Thank you to all who responded so quickly. I want to be able to get information from my JTextFields in one class and put it into the Film class parameters of the class below. The film class is a JavaBean.

    try {
      FileOutputStream file = new FileOutputStream(name + ".ser");
      ObjectOutputStream output = new ObjectOutputStream(file);
      output.writeObject(film);

Many Classes Vs Many Methods in one class

Can any one tell me what are the advantages & disadvantages - and which is better?
Having many methods (say about 15) in One class - about 10 doing various actions and not interrelated at all.
Vs
spliting the methods to be in their own classes, and instantiating them only when needed? Say in this case there could be about 10 classes thus created .
Thanks
Aarvi

>
I have got a chance to rewrite the existing code that
has about 75 "unrelated" methods in one class. ( do
not throw me out of this community now).
When I said, these methods should be put in their own
class based on their own functionality and can be
loaded only when it is called for. The counter
argument from the tech arch (!!) here is - "Why not
have it in one class? It works now". The tech arch is
a cobal type developer.
Hate to repeat what was said above (given the source) but.....
an object is not merely a collection of methods,
So far you have referred only to the methods.
Are there any data members?
If no then all you have is a collection of methods. You can of course still break them up but doing so doesn't necessarily mean it will be better. But in terms of the "tech arch" the impact is minimal. That of course doesn't mean that testing isn't required.
On the other hand if there is data then breaking them up would be based on how the data is used by the methods. As for why you would do that, the reason for the "tech arch" would be because the reason for using an OO language is so that one can have objects. And that 'class' is not an object.

To be begin with your problem sounds like you are doing everything in one thread. So stop doing that. Second when you get it split up and if a task is taking too much time then interrupt it. No kill. Interrupt. This means the worker thread needs to check sometimes if it has been interrupted.

Accessing a variable defined in one class from another class..

Greetings,
I've only been programming in as3 for a couple months, and so far I've written several compositional classes that take MovieClips as inputs to handle behaviors and interactions in a simple game I'm creating. One problem I keep coming upon is that I'd love to access the custom variables I define within one class from another class. In the game I'm creating, Main.as is my document class, from which I invoke a class called 'Level1.as' which invokes all the other classes I've written.
Below I've pasted my class 'DieLikeThePhishes'. For example, I would love to know the syntax for accessing the boolean variable 'phish1BeenHit' (line 31) from another class. I've tried the dot syntax you would use to access a MovieClip inside another MovieClip and it doesn't seem to be working for me. Any ideas would be appreciated. Thanks,
- Jeremy

I would approach it in much the same way as you would in java, by making getters and setters for all of your class variables.
Getters being for returning the values, Setters being for setting them.
So you would make a get function for the variable you want to access ala:
function get1PhishBeenHit():boolean {
return this.phish1BeenHit;
Then to access the value of that variable from outwith the class:
var result:boolean = ClassInstanceName.get1PhishBeenHit();

If there are two synchronized methods in one class.

If there are two synchronized methods in one class then what will be the beheviour of the threads accessing the methods.

Synchronization is on objects, not methods or classes. A thread, entering a synchronized method, synchronizes on the object on which that method is called. Another thread, attempting to synchronize on that object, will be made to wait until the first thread releases it.

Accessing private method of a class from report

Hello All,
I would have to access a private method of a class from a report.
Is it possible to access private mehod otherthan from its own class and friend classes.
Please guide on this. If is possible, to access please give some sample code.
Thanks & Regards,
Vishnu Priya

Hi,
By using the friend concept you can access private attribute or method in outside class.
Try the following code,
CLASS C1 DEFINITION DEFERRED.
CLASS C2 DEFINITION CREATE PRIVATE FRIENDS C1 .
PRIVATE SECTION.
DATA : NUM TYPE I VALUE 5.
METHODS : M2.
ENDCLASS.
CLASS C2 IMPLEMENTATION.
METHOD M2.
WRITE:/5 'I am method m2 in C2'.
ENDMETHOD.
ENDCLASS .
class c1 definition.
public section .
methods : m1.
endclass.
class c1 implementation.
method m1.
DATA : OREF2 TYPE REF TO C2.
CREATE OBJECT OREF2.
WRITE:/5 OREF2->NUM.
CALL METHOD OREF2->M2.
ENDMETHOD.
endclass.
START-OF-SELECTION.
DATA : OREF1 TYPE REF TO C1.
CREATE OBJECT OREF1.
CALL METHOD OREF1->M1.

Is there any way to call methods of one view from another

Hi experts,
I am new to webdynpro.I am having some requirement in which I need to call methods of one view from some other view of same component .So is there any way to do this.

Dear Pradeep,
This will solve your problem......( plz 1st read everything ..)
There are 2 views :
i) Mandatory Attributes ' view(V1)
ii) Button' s View..(V2)
1. Create a method in Component Controller.( M1).
2. Goto V2 . In the Action Handler method of Button , call method M1 of component controller.
3. Write your Code in M1 instead of V2 method.
4. Create an EVENT ( E1 ) in component controller.
5. Fire this event from M1 before executing Action Code.
6. Now Add the event handler method of E1 in V1 ( i.e. Mandatory attributes view. ) ..........clear????? .. set "METHOD TYPE" = Event Handler. instead of Method.
7. In this event handler method in V1 , write the "check_mandatory_attribute_view" method.
8. use necessary flags..
Regards ,

Is it possible to reference one cell from the value of another e.g.
value of b1 = value of c(value of a1)
So if a1 = 3 then b1 = c3, if a1 = 5 then b1 = c5.

Excellent!

Works like a dream.
