follow this...

make one System variable named JAVA_HOME
Set its value to the jdk home directory. like C:\Sun\SDK\jdk

now make one more system variable named path
set its value to the bin directory of your jdk. like C:\Sun\SDK\jdk\bin

you're done now.

Now open command prompt and type javac and hit enter.
If you get a list of help commands,bingo,you did it.
If not...bang your head thrice against the closest wall and repeat the pocedure till you get it right.

Nice!
are you know all info about Java?

i learned it but i like C++ than java

nandini

These are the basic things. I am also new to java so know a little bit only.

If you like C++ then you'd love java as well,unless you don't look down upon the persons who're not system programmaers.

I learned Java As well as advance Java(n/w Programming not in details just overview) & etc.

@ NPU.Open notepad & type this:

set JAVA_HOME= C:\JDK1.6
set CLASSPATH=.;%JAVA_HOME%\lib
set path=%JAVA_HOME%\bin;%path%
start

Save it as a batch file i.e. with extension .bat like NPU.bat.
Note : I have assumed in underlined line that you have install jdk under C:\JDK1.6 name. If you have installed it under any name replaced it with it. You will get a command prompt after executing this file. You will have to use this file again & again when you want to compile. So save it a desktop. It will open in milliseconds.

This will solve your problem .
I have suggested this solution as it is much better to create a batch file as you might not have permission to change global variables everywhere you are expected to compile a program. So this method is better than changing the environment variables.
If there is any other problem pm me & I will reply here.

Learning C++ is complete wastage of time I too learned it. C is much better for use in system programming. Also Java & C are much better for embedded systems programming. You can do now anything with C which you can do with C++.

(C++) - (troubles) =(Java)

There are a lot of online resources/source code available. I will suggest one book for you "Thinking in Java" as it is very much interesting while learning Java.

SE is the standard edition (Core Java APT), used for writing any normal application like a desktop application.

EE is the enterprise edition - it is there in the standard jdk. This is the API for EJB (enterprise java beans) to be deployed in application server like jboss, websphere, weblogic, tomcat, classfish,etc.

Netbeans is an IDE from SUN (now opensource) not a java version.
[/QUOTE]

For beginners I suggest using simple editors like editplus, notepad++, etc (suppoers sytax highlighing). Jcreator is good IDE and fast too compared to others. You can create, manage everything like debug, compile, create jars, etc. Eclipse, netbeans are having lot of features beyond the normal debug,compile, etc. (like mobile application,silverlight support, plugin,EE application and deploying to application server,remote debugging, etc,...) which as a beginner may not require.

I just started with notepad still I use kwrite as I am full time linux user (equivalent to notepad in windows) though one of the interface to our ERP is eclipse plugin interface. My colleagues use editplus, notepad++, jcreator, eclipse, netbeans.

The advantage of using IDE for beginers is they all provide pohelp for methods, member varibles. constants,etc, while using simple editors you have refer java documentation every time.

This post is nostalgic! Brought back my Java programming days (nothing special, just college days )

----

As for the new form on programming is concerned, count my vote in

@npu:
I think most people have suggested good enough books. Herbert Schildt is a good author, you can try that book (Java: Complete Reference)
As for online tutorials, Sun's website itself is comprehensive.

Good luck!

nandini

go to computer->properties->advanced->Environmental Variable

There you can set system variable.

Luke Skywalker

Wait for one day I am installing windows to solve this issue. Can't understand as path is showing bin in the path.

newprouser

hey luke, sorry i forgot to update here, nandini's method is working fine. now both javac and java command are working from cmd.

thanks for your help.

meanwhile what is wrong in this code ?

Saved as MyFirstApp.java.

NO problems in compiling , but in execution i get this error.

Luke Skywalker

Write main statement as

public static void main (String[] args)

So program is:-

public class MyFirstApp
{
public static void main (String[] args )
{
System.out.println("I rule ");
System.out.println("the world.");
}
}




PS: Then I am not going to install windows.

newprouser

thanks again, finally i got one program working
