How to launch the JDK 6 Update 3?
|
|
| Taurino 2007-11-16, 7:17 pm |
| Hello,
I've just downloaded and installed in Windows XP SP1 without error message
the JDK 6 Update 3 from http://java.sun.com/javase/downloads/index.jsp but I
can't see where I should launch the software. It hasn't installed any
shortcuts on the desktop or in the Start/All Programs directory. I tried to
launch .exes directly from the Java directory but nothing happens. I read in
the installation troubleshots on Java website but nothing is said about that
problem. So anyone knows how I could launch this? Thanks in advance.

Java is essentially a command-line tool. By itself, a Java command has little
visible effect:
java
If you run it from a command line you'd get a usage message. The command
needs to know what class to execute:
java -cp c:/myprojects/classes edu.hardknocks.compsci.lew.foo.ProjectOne
<http://java.sun.com/javase/6/docs/t...ndows/java.html>
Windows has a 'javaw.exe' that is a launcher for java.
Check your Control Panel 'Add / Remove Programs' utility to see what's really
installed.

| Thank you, I double clicked on this file too but nothing happened. I'm not a
programmer but I was curious to see how java works and I thought this would
display a developping interface like for Visual Basic, windows where I can
write code and compile it and run it and correct my code, etc. So I wonder
how Java programmers are doing and why I can't get this with the SDK :-)

Pleae do not top-post. Use trim-and-inline posting on newsgroups, to
establish context for the gazillions of other readers and researchers.

No, java (or javaw) runs the JVM (Java Virtual Machine) itself, not a user
process but a background one to execute Java class code.

| Hello Lew,
Thank you for your answer, I guess I should search for a visual interface if
such a thing exists for Java, it would be the easier way for me.
By the way, I've always answered before the previous answer (so there's
still context in my message), so the answer is given directly to people who
followed the thread and I don't use quotes and in-lines except if I have to
answer to particular points in a long message (especially when I'm  or
desperate to be right hehe) and as I am a human being having a discussion
and not working for "gazillions of other readers and researchers" (quote)
and to fill up Internet databases, I'll keep to my top-posting :o)

If you choose to be rude, don't be surprised at the (lack of) results that
will achieve for you.

Did you catch the link I provided for you?

There are, of course, other IDEs besides NetBeans, e.g.,
<http://www.eclipse.org/>
There is also a Java "Console" utility about which I know very little, except
that it comes with Java.

you should have downloaded a file called jdk-6u3-windows-i586-p.exe
Just execute it as you would any other exe file.
e.g.
double click it in an explorer window.
go into a dos box, navigate to the directory and type
jdk-6u3-windows-i586-p.exe
If you just want to run Java, not write your own Java programs, use
the smaller JRE instead.

After you have done that, normally you use an IDE.
see http://mindprod.com/jgloss/ide.html
to run the compiler and test your apps.
See http://mindprod.com/jgloss/javacexe.html
and
http://mindprod.com/jgloss/javaexe.html
for how to compile and execute from the command line without an IDE.

| Thank you, Lew (oops I'm doing it again above!), I've installed Netbeans and
it's exactly what I was looking for, I should have asked for it in the first
place because the SDK from Sun is user unfriendly. I've done the Hello World
program already ;)
By the way, I wasn't being rude but merely ironic, the fact is that I've
read so many scoldings about how people should write/answer/quote in
newsgroups that I don't bother anymore and I stick to top-posting as long as
the message is short and doesn't need interlines.

Actually, in this group top-posting is rude. Check out the FAQ post that
appears every five days for this group and comp.lang.java.programmer, and the
links to which it points.

In this newsgroup the convention is inline posts and trim the context. Doing
otherwise in this community is likely to reduce the quantity and quality of
help that you receive.
I'm not "scolding" you; I'm giving you helpful information.
I'm glad that my advice was helpful to you. I will look for your conformance
to this newsgroup's conventions.

| Thank you Roedy, alas I didn't find the .exe you're refering to but I'll be
using Netbeans as it seems user-friendly and documented for beginners (and
free!). Now I'll try, like in my good old days on Amstrad CPC 6128, to draw
geometric figures with flashy lights :o)

I assumed you are using Windows. On other platforms the .exe is
missing.
