Calling other classes
First off, I should note that I'm new here, and this question is probably ridiculously easy to fix, but I'll give it anyway.
I am making a game (Mini Golf) using the FANG engine (http://www.fangengine.org). I'm not sure if that matters for this problem, but it may. Anyway, the game consists of a bounce engine, a putting engine, and the levels. I'd like to have each level in its own class, with the main class containing the engines and having something like this in it.
<code>
if (ballGoesInHole)
holeOn = holeOn + 1;
if (holeOn = 2)
runLevel2Class();
</code>
Of course, there would be more if (holeOn = hole) statements. The problem? I'm not sure how to do it. The Level?Class() would just make the next level, and have to physics whatsoever. It would just draw. The physics engine would have to refer back to sprites created in the Level Classes. Is this even possible? If it can be done, how?

Ok, I think I've got a handle on that. Just one thing, however. I have an arrayList that will be added to in the other classes. So if I create an arrayList in The Main class, then how do I add to it in the other classes?Expose a public void addThing(Thing thing) method from the Main class, yes?
You really really really need to go through [The Tutorials|http://java.sun.com/docs/books/tutorial/] (or something)... you're wasting your time asking basic questions, and we're wasting our time answering them.

Passing values and calling other classes?
Hello all.
I have 2 classes(separate .java files). One is a login class and the other is the actual program. Login class(eventually exe file) should open the other class and pass the login parameters if you know what I mean. Is this possible, or do the 2 classes need to be part of one file?
Thanks alot
Milan DLogin class can be another class in another file
wht u have to do is to make an instance of login class in the class u want to use that class
like login lg = new Login();
and call method of login class
lg.setUser(username);
where setUser(String user); is a method of login class
this way u can pass the parameters to login class
i hope this might be helpful

found the problem...
i used this at the top of all the .java files....
package divelog;
then my dir tree looked like this....
/home/mohadib/java_restore/DIveLog
so i changed to
/home/mohadib/java_restore/divelog
and compiled with this....
javac -classpath /home/mohadib/java_restore DiveLog.java
then ran it with this.....
java -classpath /home/mohadib/java_restore divelog.DiveLog

How do you use a main applet to call other child applets?
Hello Everyone!
I have created three separate applets that animate different colored walkers that walk across the web page with each applet doing what I need them to do. I need to create a main applet that displays a component that allows the user to select how many walkers(1-3) they would like to see displayed walking across the screen. The main applet should call only one walker applet if 1 is selected, call two applets if 2 is selected, or call all three applets if 3 is selected.
My textbook has covered how to call other classes in an application but not a main applet calling other applets. I have gone through the tutorials but have not found anything related to what I need to do. Google didn't have any good ideas.
Another possibility that would work would be to have one applet with each walker having its own method to be called based upon the selection. Then again, my textbook didn't cover calling methods within an applet.
Any hints or suggestions would be greatly appreciated on these issue.
Thanks.
UnclewhoRemember, an Applet is nothing more than a Panel (or JPanel for a JApplet) - basically an empty graphics container waiting for UI or graphics commands.
You do not have a "main" applet as you do when you create an executable application which requires the 'main' method.
The best thing to do, is simply do an HTTP Redirect to a page created with the desired number of "walkers". In your cause, the most you'd need is 3 walkers, so 4 pages - 1 redirect page, and then a page with 1 walker, a page with 2 walkers, and a page with 3 walkers. -

Calling repaint from other Class file.
Hi,
First of all i am pretty new to Java so I hope you understand what I am trying to explain..
I am trying to create an applet which draws some polygons on the screen. For the drawing of these polygons I have created another class which is located in another package but the same project. I plan to use this second package as some kind of library so that i can simple call 2 or 3 functions in future applets to draw these polygons (which always have the same shape). In the library file i have created a contructor, a draw function and some other functions to change some properties. I also created a function that created a popup window as soon as i click on one of the polygons i have created. In the popup some buttons are available which change the color of the polygon. All this works fine, but the problem i have is the following:
When i click a button the main class (in package 1) needs to be repainted for the changes to be visable. But the main class can always be a different one. Is it possible to check in the class in the library package, which class from the main package called the class, and execute a repaint() on that class. So i have the following situation:
Package 1 (Applets):
package applets;
class myApplet extends Applet implements .... {
private Tank tank1 = new Tank(20, 20, 100, 200);
private Tank tank2 = new Tank(250, 20, 100, 200);
public void paint(Graphics g) {
tank1.drawTank(g);
tank2.drawTank(g);
public void mouseClicked(MouseEvent e) {
tank1.openWindow();
tank2.openWindow();
Package 2 (Library):
package applets.library;
class Tank {
public Tank(int xPos, int yPos, int height, int width) {
public void drawTank(Graphics g) {
public void openWindow() {
new myWindow("Window1");
public class myWindow extends Frame {
public myWindow(String name) {
show();
public boolean action(Event e, Object arg) {
return true;
So what i want to do is: In class Tank in the public class myWindow in the method action, i want to call the repaint() of the class myApplet
I hope my problem is clear to you, as you may have noticed i have a little trouble explaining it clearly..First of all thanks a lot for your reply and sorry for my way of programming. Like i said i am pretty new to Java, i am actually only programming for about 2 weeks and trying to learn from some examples on the internet.
I dont really understand what you want me to do, is it maybe possible to give a little bit of sample code? That would help me a lot.
Maybe some background information about the project will help a bit too.
I work at a company that develops automation solutions. We program PLC's and SCADA systems. Now Siemens has some PLC's that support Java applets which make it possible to visualize industrial processes. Now i am trying to figure out if it is possible to start developing own java applets for visualisation in the future. Since most programmers here have no experience in any higher programming language i want to keep it as simple as possible, by developing libraries that do the most of the programming work for them.
Now i want to create the first part of this library by programming some kind of storage tank. This tank always has a valve. when i click on the valve a popup should open with the operation button to open of close that valve. When a valve is opened it should be colored green and when its closed it should be colored gray or something. The Tank class has a couple of methods:
drawTank(); to draw the tank in my applet,
openValve(); to open the Valve,
closeValve(); to close the Valve,
After all this is created i want to be able to use this class in all my other classes and create a tank by simple making a new Tank object, draw it on my applet using the drawTank() method and open or close the Valve using the other 2 methods, however when i open or close the Valve the color of the valve should change so i must be able to call the repaint of all the classes that use my Tank class, but i want to do that INSIDE my Tank class.
If there is another way of doing this i would love to hear so, but i would help me a lot if you can explain in a little bit of sample code. It doesn't have to be really long or detailed.
Thnx in advance -
hey Folks.
Is there any way for me to make callbacks into Java to a class other then the one I invoked my native methods from?
I know how to make callbacks to the class I connected to my DLL from, but I'm looking for a way to access other classes that I have instantiated,
Thanks for the help,
RichardI would suggest you to use a callback interface, stating the standard call back functions.
Write a small interface yourself.
The objects you wish to call back on should have "the methods" u want to call back.
Either u can decide on a call back function name as u wish to, or by implementing an interface.
In the native method you want to callback to a java object, in the signature, pass a ref to object of this type.
say interface is ICallBack;
native void myAsynchNativeMethod(ICallBack theCallBack, arg1, arg2.. );
or else
native void myAsynchNativeMethod(Object theCallBack, arg1, arg2.. );
the third argument in the native functions native code should be the ref to the object on which u will invoke the call back.
cheers -
Calling methods from other classes
I have a bunch of little java files in a folder, do I need to make a package in order to access all the methods in all the classes, or can I just make an instance of any of the methods because all the classes are in the same folder?
HI,
If your methods have a "public" modifier (and the class does too) then you can instantiate your classes as objects from that (so-called) "default" package in any other class or object in any other package and then call the methods on those instantiated objects as you please.
If that sounds confusing... I'd seriously try the excellent tutorials at this site, especially "the java tutorial".

Calling a variable from main class to other class
How do I call a variable that is initialize in the Test.java into Sub.java?
I want to call the a, b, c that I have initialize in Test.java into Sub.java.
import java.util.*;
import java.lang.*;
import java.awt.*;
public class Test{
public static void main(String args[]){
int b;
int c=1;
int a=11;
b = c + a;
System.out.println(+b);
import java.util.*;
import java.lang.*;
import java.awt.*;
public class Sub{
public void Subtraction(){
if(a>c)
b = a-c;
else if(c>a)
b = c-a;
else if(a=c)
b = a-c;
System.out.println(+b);
}This is, and I'm sorry but I don't know how else to say this, a real big mess.
I'll go through some (most/all) of it but honestly....
import java.awt.*;Many will tell you that you should use specific imports and not wildcards to increase ease of reading. I am not so personally picky about this but it would help you.
import java.awt.event.*;
import javax.swing.*;

import java.applet.Applet.*;Unused. get rid of it
public class SUBOK { Terrible class name. Please use the standard [_Java naming conventions_|http://java.sun.com/docs/codeconv/html/CodeConventions.doc8.html]
public int a = 10;
public static void main(String[] args) {
SUBOK runGUI = new SUBOK();
public SUBOK(){
JFrame f = new JFrame("Subok");
f.setSize(150,100);
f.setVisible(true);
f.setDefaultCloseOperation(f.EXIT_ON_CLOSE);
JButton b = new JButton("Sum");
b.setActionCommand("send");
b.addActionListener(new Push());
JPanel p = new JPanel();
p.add(b);
f.add(p);
} Most of that is okay although not great. But I don't think you should be doing anything in Swing at all yet.
private class Push implements ActionListener{
public void actionPerformed(ActionEvent e){
if(e.getActionCommand().equals("send")){
int a = 12;You are aware that this a has nothing to do with your other a? right? I mean this is a method local variable in a whole other class then the other one.
Add i = new Add();
i.Add();
public int aValue(){
return a;
} Alrighty then...

int d = a.aValue(); Aiaiaiai.
public void Add() {
int b;

b = d+c;
System.out.println(b);
}First of all do not name a method the same as a class. Second most of this class appears to be based mainly in the realm of wishful thinking. In programming, wishing that something will "just work" without understanding the basics of why and how it works does, pretty much 100% of the time, not end well.
You need to take a number of steps back from this code, get grounded in some fundamentals and then make another attempt. I would highly recommend putting the Swing (or any other GUI) code aside for some time now. Inter-object communication is a fundamental part of OO and thus a fundamental part of Java and this code clearly shows that you don't understand it yet at all.
Start here [_Learning The Java Language_|http://java.sun.com/docs/books/tutorial/java/index.html]
If you have questions as you go through the tutorial do come back and ask them and someone here will be glad to help you. But in order to help you with code you have to be at a point where you understand things like variable scope, the difference between a class and an Object and how, why and what methods can be used to exchange information between two instances. -
ProgressMonitor in thred, call from other class
Hi all
I have a problem using the ProgressMonitor... I just want to update the progress from another class.
So what i was thinking was:
I could implement a method that invoked the thread, and thereby updating the progress.
The problem occurs when the calculating steps is going. The parent class calls ProgressDiff fine but it doesn't update it, it doesn't even show anything. Just when the task is finished it says, simulation done!!
I have tried searching alot on these forums, and on google, but all methods implementing progressmonitor uses a call from within the class. <- Not what I want. :=)
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import java.beans.*;
public class ProgressDiff extends JFrame {
public ProgressMonitor progressMonitor;
public int tll;
public ProgressDiff(int maks, String set) {
super("Progress");
setSize(250, 100);
progressMonitor = new ProgressMonitor(null,
"Differentiere og l�ser\n" + set,
"", 0, maks);
progressMonitor.setProgress(0);
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setProgressTal(0, false);
setLocationRelativeTo(null);
setVisible(true);
public void setProgressTal(int fremGang, boolean done) {
tll = fremGang;
SwingUtilities.invokeLater(new Update());
if (done) {
Toolkit.getDefaultToolkit().beep();
JOptionPane.showMessageDialog(null,
"Simuleringen er f�rdig."
, "F�rdig",
JOptionPane.INFORMATION_MESSAGE);
class Update implements Runnable {
public void run() {
if (progressMonitor.isCanceled()) {
Toolkit.getDefaultToolkit().beep();
JOptionPane.showMessageDialog(null,
"Simuleringen er f�rdig."
, "F�rdig",
JOptionPane.INFORMATION_MESSAGE);
} else {
progressMonitor.setProgress(tll);
progressMonitor.setNote(String.format("Completed %d%%.\n", tll));
}Any help would be apreciable!!

hello!
can i create a java program that can call other .exe file???
how????
thanks.Try this:
Runtime.getRuntime().exec("rundll32
url.dll,FileProtocolHandler " filename);Worked very well for me. It's like double-clicking a
file in explorer. Don't know if it works with an exe
though...try it ;-)I wouldn't recommend that way. If you're trying to "run" a ".doc" file - that isn't a process. A process is a .exe file, such as Word.exe (or whatever MS Word's application executable is). Let the shell handle it:
Runtime.getRuntime().exec("cmd.exe /C start " + filename);
where filename is a path to a .doc file, for example.
And no, there's no way from pure Java to automate the child process such as making it insert text. You'd need to program against COM (Microsoft's Component Object Model) to do that, which you can do with a 3rd-party Java-to-COM bridge (search the net for "Java COM bridge" for starters). And you'd have to know Word's COM API. -
How to call a class file in a jsp without deploying anything in j2ee
Hi,
I am new in J2EE. I have some jsps, which I configured using web.properties(documentroot=c:/jsp/). I am able to get
those pages by the web browser. I have some import statements in some jsps, now I
am trying to access those page but it is failing, it says
org.apache.jasper.JasperException: Unable to compile class for
JSPD:\j2sdkee1.3\repository\pradip\web\_0002fLogin_0002ejspLogin_jsp_0.java:1:
Class com.gui.UPMGuiGlobalConstants not found in import.
import com.gui.UPMGuiGlobalConstants;
Actually I have not deployed any class file or jsps.. Now my question is can I access
these jsps without deploying anything, like can I put my .jar file in any j2ee
directory(like lib or anywhere else, I already tried after putting in /lib) and restart the
j2ee and use it. So how can I call a class file from a jsp without any kind of
deployment?
Please send me the reply as soon as possible.
Regds,
PradipAfter you put the jar containing the class to import into the WEB-INF/lib directory, you still need to include it in the jsp.
Putting the jar into the lib dir, will make it available to the vm, but as in any other java class, you still need to import it into the class, that the jsp will be compiled into.
And you do that by putting
<%@page import="com.gui.UPMGuiGlobalConstants" %>somewhere near the top of your jsp. (well you don't need to put it there, but it good style ;)
That should do it. -
How can I call the Class and have a PDF appear in seperate window?.
I would like to call the class/interface ZCL_UIU_PRN_ACCOUNT2, method Collect_data and have a Smartform executed to produce a PDF document in a Seperate window.
Where I have an issue is in opening another window to display the PDF.
I know the Standard PDF Facsheet does exactly this, but that is triggered via the Web browser and calls a Java script, avoiding and events and round-server trip processing. I would have changed the button values so that when pressed it does process the various events and eventually ends up at EH_ONPREVIEW for the BP_HEAD/Overview. I know just need to open a new window and call the process to create the PDF via Smartform.
Any suggestions would be more than welcome. I have spent so much time on this, and have gained no real ground, so far.

Calling a class's method from another class
Hi, i would like to know if it's possible to call a Class's method and get it's return from another Class. This first Class doesn't extend the second. I've got a Choice on this first class and depending on what is selected, i want to draw a image on the second class witch is a Panel extended. I put the control "if" on the paint() method of the second class witch is called from the first by the repaint() (first_class.repaint()) on itemStateChanged(). Thankx 4 your help. I'm stuck with this.This program is for my postgraduation final project and i'm very late....
