Latest version java is java 1.6. You need to install Java SDK 1.6( or 6). You may follow below link, I hope this works for you.

Can you give us more details?

What are you attempting to run? How are you attempting to run it? And how is it failing?

What operating system are you using?
Can you open a command prompt window (Windows) or a terminal/shell Window (Unix/Linux) or whatever you use on Mac OS/X?
Open a command prompt/shell. Write the following two commands:

java -version

javac -version

If you get a sensible response, eg 1.6.0_06 for both, then you are all right. If you get something like "java is not recognised . . ." then you need to download and install Java. Go to the link Jaspreet Aswal gave you, or here, and click where it says JDK6 update 6. Both links will get you to the same place eventually.
Make sure to follow the installation instructions, including the bit about updating the PATH. The PATH is very important; Java won't work without a correct PATH.
There is usually no need to do anything with your CLASSPATH at this stage.

If you have any more problems, please be sure to come back here.

Hi Guys

I installed JDk1.6... in my system under the path is
C:\program files\java\jdk1.6
then i changed the environment var i.e
i append this line to the exsisting path
now i opend the command prompt typed java it is regonized but
i typed javac it saying
C:\Program Files\Java\jdk1.6.0_06>javac
'javac' is not recognized as an internal or external command,
operable program or batch file.

so just wondering if i want to write a simple code helloworld in which directory i have to write is it in JDk1.6 or Bin
how can i set the classpth exactly

Please help me

[Jesper de Jong]

You need to add the bin directory of your JDK installation directory to the PATH. So if you installed the JDK in C:\Program Files\Java\jdk1.6.0_06, then you need to add:

C:\Program Files\Java\jdk1.6.0_06\bin

to the PATH (not the JDK directory itself). The JDK installation instructions explain exactly how to set the PATH.

Hi,

I have 3 jre folders in the C;\Program Files\Java

jre1.5.0
jre1.6.0_02
jre1.6.0_05

So shall I delete them all or uninstall it and install the new one of jre1.6.0_06?

And I forgot what is the name of software for java coding? I try to google.

Ta,

Jak

See the link in Jesper's reply for details. But note that it's the PATH you want to update -- not the CLASSPATH. These are different things.

You have different versions of the JRE (Java Runtime Environment). But to code Java, you need the JDK (Java Development Kit). See Campbell's link above, and be sure to follow the advice about updating the PATH variable when you install.

[Campbell Ritchie]

No, you ought not to delete the older folders. You should use "install/uninstall programs" to uninstall the older versions of Java.

[Rob Spoor]

Actually, it's called Add/Remove Programs, and is located inside the Windows Control Panel.

I just remember now that the name of the software is Kawa for Java coding. Last time I used it was 5 years ago at University and I didn't learn the module fully properly. Why it was called Kawa? I must have missed the JDK underline.

So JDK is a software to code then. I'm going to download and install it now on my macbook and window laptop.

Thanks

So, basically, (1) you haven't done "Java" coding for 5 years, when you learned it, (2) you didn't learn the "module fully properly", and (3) you never learned Java. On the last point, isn't Kawa based on Scheme?

Henry

[Larry Dillions]

Kawa is for Linux, I remembered that my tutor installed kawa in my computer which was window98. http://www.gnu.org/software/kawa/index.html

Anyway I won't download it. Look like there is no SDK for mac?

That's right! But on your last point, I don't know what do you mean by isn't kawa bases on Scheme!

Sorry

Scheme is a programming language. It is very similar to another programming language called Lisp. It is completely different from the Java programming language.

Take a look at the link that you posted. Basically, Kawa is an environment that takes Scheme and compiles it to run in the Java runtime environment. It basically allows you to program in Scheme but run the application in environments meant for Java. You don't have to program a single line of Java.

In other words, you never "fully properly" learned Scheme. You never was taught Java at all.

The link that Jesper provided is very specific (and detailed). What parts of it did you follow?

Yeah, I absolutely agree with you! Tut tut. I will, one day! At the moment, I'm on chapter two in the Head First Java book.

Hey open the command prompt and go to the folder where you have the java programs and give this command in the command prompt.

set path=C:\program files\java\jdk1.6\bin;.

this will set the path for you. now try checkinng the path by giving the command in the command prompt java -version

Regards
vishnu

[fred rosenberger]

you can write your code in any directory you want. it doesn't matter.

First, can you find a javac.exe on your computer? it should be somewhere like

C:\Program Files\Java\jdk1.5.0_12\bin

go into that directory, and find the program. see if you can run it from there. if not, you have some larger issues. if so, make sure THAT directory is in your path. once you set the path, you may have to open a new command window or whatever. you can verify it's there by typing 'path'.
