How many components in Java

Hi, this is just a simple theory question. Is there one out there could tell me the answer. How many components are there in Java ?
Thanks,
choongteck

As many as are derived from the Component-Class plus 1 (for the Component-Class itself)?
Would you like to know the total number of classes or the number of instances of the classes? :)

How many package in Java 1.1?

Do you know, How many package in Java 1.1?

Idiotic question, so here's an idiotic reply:
jar tf /path/to/java/lib/rt.jar |\
   egrep -v '^(META-INF|com/sun|sun)' |\
   sed -e 's/\/[^/]*$//' |\
   sort -u |\
   sed -e 's;/;.;g' |\
   wc -lAnd if you change the last wc -l to more, you'll see the actual package names.

How many classes in Java?

I'm new to Java.
Does anyone have a link or know the exact number of classes and methods in the java programming language that we use and their classifications (e.g. how many number of classes are used only for drawing rectangular objects on a form and the names of those classes)
I need to see ALL the possible classes and categories they apply to.
Is there a source I can access to view such information?
Appreciated.

wow.... now about that zipped file with so many class definitions, maybe an extra strap and a java programmer to sit on the thing to prevent it from exploding.
thanx for your help people.

How many systems in Java Development landscape?

For our J2EE development, we have installed a system with the JDI that we also classify as our Dev system. Our QA system would be the test system.
But in the setup of NWDI systems, there is Dev, Consolidation, Test, Prod. Can the NWDI/Dev system also be the consolidation system? We don't really want to introduce 4 systems because our development activity is relatively simple. I'm still thinking with an ABAP/STMS mind and trying to make the assimilations of how we've done it in ABAP for 10 years can translate to doing the same thing with a Java development environment.

How many versions of java console do I need in extensions?

In extensions I have java consoles from 6.0.11 to 6.0.24. Can I remove the old old ones? Mike

You do not need any of them. They are not needed to run Java applets.

How many passes is javac?

Does anyone know how many passes the java compiler uses?

Parser Tree builder pass..... Type Check on the way back up the tree..... generate code..... Maybe? I can't find it anywhere.... I'll tell you tomorrow though... I'll go ask DL... I bet it's different for the pre Java2 compiler also, as the Java2 compiler is completely new... Did you notice all the great error messages went away with Java2 compilers? now they just all say "can't resolve symbol"...

How many classes should a .java file contain?

Are there any general guidelines on how many Java classes should be contained in a single .java file? I've been creating a new .java file for each class I write but see examples in Sun's Java tutorial where there are at least two classes in a single .java file. One such case is the TableDemo example at
http://java.sun.com/docs/books/tutorial/uiswing/components/example-swing/TableDemo.java
Thanks.

The example you point to isn't really more the one class in one java file. It makes use of an inner class. An inner class is something different! As far as I understand it, it is mainly used to implement some behaviour (in this case AbstractTableModel behaviour). If the MyTableModel was in a separate class file, it couldn't access the variable of the main TableDemo class. So they use an inner class.
So unless you need inner classes, this example is no reason to put more than one class in a .java file. In general, just put one class in a .java file. It's easier for everybody.

How many frameworks available in Java?

How many frameworks available in Java? Which are most commonly used?
Edited by: Passion on Jun 16, 2008 2:50 AM

the number of available frameworks is a function of time, climbing asymptotically to a number n where n is larger than 0 and probably smaller than infinity.
The value of n is an unknown, and possibly cannot be known at any time Java is in active use.

How many Java in control panel??

There is: Java2 Platform Standard Edition Runtime Environment Version 5.0, SE v1.4 2_13, JavanPlatform, Standard Edition Runtime Environment Version 6.0.30, then Java 2.0 download manager.Okay
Also,after 6.0.30 installation I have problem with opening .pdf documents from any website. I seriously doubt this has anything to do with your Java installation.

How many classes are there in the java kit?

i figured this was the most "general" forum to post this question in. and im curious to know, how many packages/classes/functions are there in the java sdk? like, all the prebuilt ones. ive looked but cant seem to find any info on it. anybody happen to know?
Thanks!

there are at least 4142 classes in the 1.4.2.x distribution ...Is that the number of files which end in .java? There's bound to be a lot more
classes, when you u consider inner classes and especially anonymous
inner classes.It was just a rough estimation ... and I wrote 'at least' 4142 classes ...
and I was wrong: there are alse 4 .h files in the src.zip file, so that makes 4138
classes at least :-)
kind regards,
Jos

The literal pool is part of the heap, and it holds String instances.

You're referring to the JVM. That's not Java.It's part of Java.
There is nowhere in Java where it is correct to say "The string literal pool holds references, not String objects."
