Source code of Java

Hi friends,
I hope there must be some resourse of source code of Java.I have look a directory in jdk1.3 named src.But what is procedure of viewing the source code of Java.
Regards,
Hassan

You could use winzip to view it. This post should be in the beginner forum though.

I am moving this to Java in General (beginner)

If you have the src directory already, then you should be able to view the *.java files with any text editor.
If you don't have the src directory or it doesn't contain any files, you can expand the compressed file src.jar with the following from the command line:
jar -xf src.jar

Thanks Michael.
I have got the src.jar file & after using the command u recommend i got src folder.Now the problem is that when i open src\java\io\ByteArrayOutputStream in notepad i got code in very haphazard way.It is not organized it contains @ , boxes, etc...
plz. help me.

The best way to view the source code is with all the
documentations in the source code.So follow this step..
After extracting, you will get to see the different packages
under the java package.So to view all the files say in the
lang package.. type javadoc *.* at c:\jdk1.3\java\lang\>
This will help you in seeing the source code with the
documentation

Hope this helps,

Hi Manjunath,
I have done exactly what u said.Just i made the small changes in path i.e c:\jdk1.3\src\java\lang>.After executing the cmd u mentioned i get a series of statements some thing like this....
Loading source file System.java.
Loading source file Thread.java.
Loading source file ThreadDeath.
Loading source file ThreadGroup.
.................etc.
But i didn't got any htmsl file or any new file in ...java\lang>.However i tried the same cmd. at this path,
c:\jdk12-doc\jdk1.2\docs\api\java\lang>
It creats all the coresponding html files.But still unable to see the source code.!
Plz. help. me
Regards,
Hassan.

Hassan, do you have WinZip or File Librarian or PKUNZIP on your machine? Any one of those will allow you to extract the file that you want to read.

However, when I use Notepad, I see:

ByteArrayOutputStream extends OutputStream { < snipped >

Is this what you see? Perhaps you need to use a different text editor to view the source code.

Still unable to open source code

Hassan, What you are seeing is the source code.

The source code that Sun puts out is fully documented with JavaDoc comments (that were used to create the API that we all know and love). The code is intersperced within the comments.

So much thanks Jane & Cindy!.

Hassan.
