How to call inner class method in one java file from another java file?

hello guyz, i m tryin to access an inner class method defined in one class from another class... i m posting the code too wit error. plz help me out.
// test1.java
public class test1
     public test1()
          test t = new test();
     public class test
          test()
          public int geti()
               int i=10;
               return i;
// test2.java
class test2
     public static void main(String[] args)
          test1 t1 = new test1();
          System.out.println(t1.t.i);
i m getting error as
test2.java:7: cannot resolve symbol
symbol : variable t
location: class test1
          System.out.println(t1.t.geti());
^

There are various ways to define and use nested classes. Here is a common pattern. The inner class is private but implements an interface visible to the client. The enclosing class provides a factory method to create instances of the inner class.
interface I {
    void method();
class Outer {
    private String name;
    public Outer(String name) {
        this.name = name;
    public I createInner() {
        return new Inner();
    private class Inner implements I {
        public void method() {
            System.out.format("Enclosing object's name is %s%n", name);
public class Demo {
    public static void main(String[] args) {
        Outer outer = new Outer("Otto");
        I junior = outer.createInner();
        junior.method();
}

How to convert a class file to exe file and how to cteate a class file to d

how to convert a class file to exe file

Hi Bhaskarq,
Hi,
It is not at all possible.
But it is a really worst method.
Please go through it.
This is a very common question asked in the comp.lang.java newsgroup. Its often useful to have an
executable application when deploying your
applications to a specific platform, but remember to
make your .class files available for users running
Unix/Macintosh/other platforms.
Microsoft provide a free system development kit (SDK),
for Java, which includes the jexegen tool. This
will convert class files into a .EXE form. The only
disadvantage is that users need a Microsoft Java
Virtual Machine (JVM) installed. If your target
platform is Win32, you can either redistribute the
virtual
machine, or raise the level of your system
requirements, to include Windows 98, or Windows 95
with
Internet Explorer 4. Systems matching these
requirements will already have a copy of the Microsoft
Java Virtual Machine installed.
Note : You must specify all of the class files your
application needs (except for standard java packges)
as a parameter, so if you have third party libraries,
you'll need to include them as well. You can use wildcards * though, and you don't need the original source code.
Also please see this Forum which will give a good idea

               e.printStackTrace();
But its giving class cast exception. Please help on this..

Do you mean "two different layers" as in separate JVMs or "two different layers" as in functional areas running within the same JVM.
In either case, if the first class is actually semantically and functionally the same as the second (and they are always intended to be the same) then import and and use the first class in place of the second. That's beyond any question of how to get the data of the first into the second if and when you need to.
Once you make the breakthrough and use one class instead of two I'd guess that almost solves your problem. But if you want to describe your architecture a little that would help others pin down want you're trying to do.

How do you convert a jar file into a java file, ?

how do you convert a jar file into a java file ?
I am new to Java ,but have a little experience in C++ and Visual Basic.
I want to edit and maybe create my own mobile games that are written or converted into jar files.
At the moment I am using Java NetBeans , and Easy Java( the java pad).
However the only solution I tried was to open the JAR file in winrar and see that its made up of png picture files,
midi music files and class files. Unfortunately when I uncompressed the JAR file , there was NO java file to be seen and the JAVA editors Do not show the class file like a Java file. So why is there no extension Java file in the mobile JAR game ?

how do you convert a jar file into a java file ?You generally don't. There exist decompilers, but if you're meant to have the source, you should either have it because you are the author, or you should be able to get it from the author.

I want to edit and maybe create my own mobile games that are written or converted into jar files.Eh?
Are you saying you want to take existing games and modify them? If the creators allow you to modify their source, then they'll provide you with that source (the .java files). If you're allowed to add things but not modify, you don't need .java files. Just documentation, which, again, the creators should be providing.
Or are you saying you want to create your own games and distribute them in jar files? If so, there's no need to turn jars into .java.

How to convert Oracle reports previewer output into delimited file.

How to convert Oracle reports previewer output into delimited file if the report has more than 1000 pages.
I tried with previewer option File --> Generate to file --> Delimited file, but the report engine is crashing.Not generating .TXT file.
I observed that this option is not working for more than 400 pages.
I am using Oracle reports 6i version.
Plz suggest me to generate .TXT file from Report previewer.

You can specify a delimiter (a character or string of characters) to separate the data (boilerplate or field objects) in your report output in either of the following ways:
On the command line using the DELIMITER keyword.
In the Delimited Output dialog box or DelimitedData Output dialog box (displayed with File > Generate to File > Delimited or File > Generate to File > DelimitedData) in Reports Builder.

How to view the change immediately after a java file is modified without restarting server or redeploy?

          Hi All,
          How to view the change immediately after a java file that is used in jsp is modified
          without restarting server or redeploy?
          Moreover, it is better to keep the original session.
          Any suggestion is appreciated.
          Kammau


          Hi,
          In order to have a new version of a java class, the current classloader must be
          deleted and a new one created. This is what redeployment does. I believe that
          this is more of an issue with Sun's implementation of classloaders. You could
          ask BEA support (719.232.7878) and see if they have any plans to periodically
          check jar files to see if java class file timestamps and destroy and re-create
          classloaders on the fly.
          1) You will still have to accept the performance hit of destroying classloaders
          and creating new ones. There isn't any way around that.
          2) I would think you would want to have more explicit control in production and
          integration anyway.
          You can redeploy applications from the command line (script) file not just the
          console.
          Hope this helps,
          pat

How to call a html file in a java file

how to call a html file inside a java file ?

Hopeless. Are you by any chance a rare gas? You seem completely inert. LOL You totally pwned him there :rolls eyes:
well, no, I think he's looking for something to this degree:
in HTML, there is a mailto: command that makes the system default handled way to email emails open up. He's looking for a command thats very nice and opens a html file in the system default browser.
So, Dick, Runtime.exec would work execpt that he needs a way to find the default system browser to call exec on, AND he has to know how to pass html file locations to the executable via command line arguments
He just didnt try to phrase it at all :P

Very Urgent--- How to Convert Non Valuated stk into Valuated

Dear GURU'S
Actually for a material A when i see the stock in MM03 in accounting tab i see less stock then when i see in MMBE
i.e in MMBE if i select Material A and Plant B(Which is depo in my case) i see stock as 39
but for same material MAterial A and Plant B ,if i see in MM03 --in accounting tab i m able to see less stock i.e only 1
============================================
Well the problem is In MM03 I cud see only valuated stk i.e qty as 1
And in MMBE for a partiocular material for a particular plant the stock was 39
i.e Here i am getting Valuated + Non valuated stock
i.e i am getting difference of 25
=====>>>
To get into the root cause
I have gone to MB5B where i can get all the transaction that has been done on this material with movement type also i got the intial stock ,Goods recpt ,Goods issu and total stock
No for a particular material
In MB5B it is showing
Stock on 01.01.2005    = 38
receipts total               = 238
Issues total                  =237
Stock as on 18.02.2008 = 39(which is equal to Stock in MMBE)
=============>This is for valuated +Non valuated stock
Where as if i want to see only valuated stock it was showing
receipts total      = 238
Issues total         =237
Stock as on 18.02.2008 =1 (which is equal to stock in acctg view in MM03)
====================>This is only for Valuated Stock
======================================
Now how to solve this :
The initial qty(38) which has been posted it was at the begining that is at the start of the project
And the people who have posted it ,it was non valuated
that is the reason it is showing difference in MM03 and MMBE
First thing
How can i see on which date this initial stock has been posted
Second Query
How to convert this non valuated stock into Valuated stock
So that the quantity in MMBE and MM03 gets matched
Willl award 10 Points if my problem gets solved
THANKZ IN ADVANCE

Dear friend
Actuallly i have checked the history of that particular Item in MB51
I have gone through all the documents created for this material
Now this material also exist in DEPO which is located at chennai and plant is at mumbai
So Initially in the year-2006(31-10-2006) whater documents are created i.e STOP has been created and delivery has been made (Mov type-601)
are non valuated stock ,means they have been posted without any valuation
But from year 2007(01.02.2007) the documents whiohc have been posted are valuated
i.e is the reason when i am executing transaction MRN9 to check the history of valuated stock
I cant see non valuated stock
Well now how to do the valuation of this stock which have been posted in year 2006 so that
In MMBE and MM03 there is no difference of stock
Plz hepl
