Need to find the source code for java.util.LinkedList

Hello all,
I'm new to the forums and I actually need the LinkedList source file as well as all the source files for all Java packages and libraries. Please post a link here if you can, or email me at [email protected]
Thanks again!

But those must be platform dependant, not really that
interesting to look at. I have never felt any need to
look at those at least.Wake up and smell the coffee, abbie! I read the source code all the time and constantly tell my students to do that, too.
1. Java source code is not platform dependent. The original poster wanted to look at linked list code, how could that be platform dependent?
2. It is the implementation of the SDK APIs, so by definition it is implementation dependent code, liable to change in a later version. So don't assume anything beyond what is claimed in the API documentation. However, sometimes the documentation is incomplete or ambiguous to you, and reading the source can provide some insight, however implementation dependent. (Light a candle or curse the darkness.)
3. Why read source code? It's a good way to learn how to program. You see something in the API and ask: how'd they do that? Or you realize you want to do something broadly similar, but you can't reuse the source code.
For example, Images are not Serializable, but suppose you want a small image that is part of an object to be serialized with the rest of the object without too much fuss (ie, without using javax.imageio). You notice ImageIcon is serializable, so you use it. (An ImageIcon has-an Image.) Then you wonder: how'd they do that? You read the source and then you know.

1. How we can get the Java Source Code and where and which directory we need to look into?
2. Let say if we need to customize the java file how we can do that?
3. where and which directory we have to complie the java file?
Highly appreciate for any pointers
Thanks,

Where to find the source code for MenuTreeListPreviewLayoutController

Dear All!
I am desparately searching for the source code of the MenuTreeListPreviewLayoutController. I would like to
implement a similar Layout Controller than the above mentioned one, but cannot find the code.
Is anybody able to help me?
Cheers and thanks in advance
Ingo

Hi Ingo,
you should be able to find and decompile the class com.sapportals.wcm.rendering.layout.cm.MenuTreeListPreviewLayoutController in the JAR km.appl.ui.flex.control_core.jar. This JAR is located under ...<irj-root>\WEB-INF\portal\portalapps\com.sap.km.cm.ui.flex\private\lib
Hope this helps,
Robert
PS: If you have problems to find it, gimme a mail and I'll send you the decompiled version.

If you have no tool, you can write your own tool:

          new ZipTest().unzip(sourceFilename, targetDirectory);
     public void unzip(String sourceFilename, String targetDirectory) {

Where can I find the source code of java.*?

Hey guy
Is there any way I can get the code of the classes under java.*?
Some of the javadocs online are not quite clear to me,
so I hope I can check the code directly instead of looking at the javadocs
Thanks!

A word of warning: the java.* classes do NOT necessarily represent best/current software engineering practices in general. Some classes have been extensively optimized at the expense of readability/clarity of the code, while others represent specific/peculiar implementations of software patterns that are the result of historic baggage.
In general, any time you use "but that's how it's done in this or that java.* class" as an argument in a discussion, you'll likely lose.
(note that this does not mean the java.* classes are rubbish, just that they don't necessarily make a good example to learn from)

Find the source code of Portal

I need to customise the portal. I need to find the source code of the portal.
Please give the path where i can find the source code.
Thanks in advance

Hi Hexaware Consultants,
To change the look and feel of MastHead iView ...
-The three main files in the masthead are HeaderiView.jsp,LogInRedirect.jsp and LogOffConfirmMsg.jsp
-The HeaderiView contains the masthead users see when they are in the portal.
-Once you added your link to the HeaderiView.jsp,upload the par file.
-Once the par file is uploaded to the portal,you need to create a masthead iview based on this par file.
-Then this iView will be used for masthead on the framework page.
-create a folder in portal catalog-right click the folder->create a iView from par->select your own masthead iView->choose next->choose default component and click next->Enter the properties like-iView name,iView ID,prefix,Save as -iView and click next>save.
Here is the important step :
Add the iView to the framework page,then only it will be visible to the end users.
Browse the ramework page being used by the portal in the portal catalog
Right click on he page->edit->Page Layout->Select masthead iView on the framework page and click remove.
now iViews(Right click)->Widgets_masthead->Add iView to page->Delta Link->Position the masthead.->Logoff and logon to the portal.
It should work fine for you now I guess.
Thank you.
I was also working in Hexaware 2 years back

Karthick

Where can I find the original code for class in Java API

I am learning Java programming and wanted to see how professionals handel all cases. Can anyone tell me where I can find the original implementation code for classes in Java API? It would be a great help for me.

the basic source is where you installed java in a file called java.src, its either in the main dir of one of the sub dirs ( mmm ), contains all the source code for all the classes in the api.

How do I see the source code for 'NI Example Finder'?

At the LabView Express demo, the rep showed us how to view the source code for 'NI Example Finder' (started with Help, Find Examples...). Please refresh my memory.
--todd

There are a couple of VI's that shipped with LabView 7.0, but you can't see the diagrams.
C:\Program Files\National Instruments\LabVIEW 7.0\resource\system\HelpServer.llb\Run Example Finder__NATIONAL INSTRUMENTS.vi
Press Ctrl-E on this VI and it prompts you for a password.
This VI is run by C:\Program Files\National Instruments\LabVIEW 7.0\resource\system\HelpServer.llb\HelpServer__NATIONAL INSTRUMENTS.vi
There's also C:\Program Files\National Instruments\LabVIEW 7.0\help\_exfinder.llb\Example Finder Launcher.vi.
Tyring to open this VI starts the NI Example Finder. Note the taskbar icon which is different from the normal VI icon.
It seems like NI is trying to keep us out, even if it used LabView to develop the Example Finder.

JLundan,
I want to thank you for responding to the thread I started on the forum at java.sun.com. Your solution to my problem of needing to print the code of the html pages that the file I included generates was just what I was looking for. However, I have some further questions to ask, if you don't mind. To clarify my task I should say that your rephrasing of the problem is accurate: "You wan't to display the contents of the HTML file that the web server produces in response of client's request?"
Yes, this is what I need to do, but also it needs to display the source code of that html file that the server produces in response to the client's request. Also, in this case, I am the client requesting that the server return some html file, and I'm not sure where the server is. But the webserver.java file that I shared on the forum is on my local machine. I was wondering if I could modify this webserver.java file at my home so that any html file the server returns to me would automatically display the source code. This is a school project of mine and I am stuck on this one thing here.
Further, where would I put the "foo.html" file so it can be written to?
FileOuputStream fos = new FileOutputStream("foo.html");
fos.write(bytes);
fos.close();
Thanks so much for your help. I look forward to your response, at your convenience.
Regards

Finding the source code from Jar file

Hi,
I am a beginner java programmer but have been entrusted with learning our company's Java application. The architect of the application is not forthcoming in sharing information and so I need help in tracing the source code for the application. I know where the .jar files are stored but I don't know where the actual .java or .class files are stored.
In the .profile file, I see the classpaths set to various jar files. eg.
CLASSPATH=$PATH:/eaid01_apps/merc01/libs/tools/java/drivers/bin/eaiRun.jar
When I view this jar file with command "jar tf eaiRun.jar", it displays all the files under it. Onc such listing is as following:
citi/eai/EAI.class
citi/eai/Interface.class
I want to go to that specific directory on our file system which is storing these .class or.java file. From what I have learned about packages, I should find some folder called 'citi' ,'eai'.
However I am not able to find these folders anywhere on file system. Is there a way I can find where the actual souce code is by looking at the jar files.
Please help. Let me know if you need more information.
thanks,
Anand.

Is there a way I can find where the actual souce code is by looking at the jar files.No, in general you can't, you should ask the architect that you mentioned earlier. The name of the source file is sometimes stored in the .class file for debugging purposes but that's unlikely going to help you find the files.
You should also ask if he/she has got any documentation of the system. It's often a lot easier to follow documentation written in human language than program code written in a programming language. There could be documentation in a format similar to this: http://java.sun.com/j2se/1.4.2/docs/api/

Where's the source code for the MIDP 2.0

Hi
does anybody know if the source code for the MIDP 2.0 is available anywhere, if so please give me the link, I've searched for it but couldn't find. I need it to create a custom class based on the Command class, but need to have a look at the source code of the "Command" to make the appropriate changes to my extending class, so I can't do it without a look under the hood.
Any help would be greatly appreciated

You can find reference implementations at http://java.sun.com/products/midp/index.jsp
But they are only to assist manufacturers in implementing their own versions, and do not necessarily reflect the code running on a given device. All you can assume is what is stated in the MIDP specification. However, reading the RI code may help you better understand the spec.

Is there any differnce between the Numeric Limit Test source code from TestStand 3.0 to TestStand 3.1? How to get the source code for the Numric Limit Test for both the versions?

I need to know the differnece between the Numeric Limit Test between the TestStand version 3.0 to 3.1. If there is any differnec in the source code how to find it out? If somebody has the code can you share it?
Thanks,
Jeyan

Hi,
I don't believe there are any differences between the two versions. But you can check the source code for the Numeric Limit Test in TestStand\Components\NI\StepTypes\CommonSubsteps. But the main part of the step is the Code Module and this bit the users supplies this.
What has prompted this question?
