First of all if you have already java then uninstall that java and download Java Sdk from Sun Microsystem :
For download: jdk (Java Development Kit)
Then choose your appropriate Operation System and download and Install the *.EXE program
This is one of the tough point for beginner to install java Beginner.
Some of the steps to maintain Path of Java compiler are given as follows:
STEP 1: Right click on My Computer and Go properties.
STEP 2: Dialogue Box Appears (given in fig 1.1) Go to Advance Tab > Environment Variables..
Fig 1.1 A Dialogue Box of Advance Tab
STEP 3: Now in New Dialogue box (given in fig.1.2 ) You can click on New Tab for creating new variable
Fig 1.2 Environment Variables Dialogue Box
STEP 4: New Small Dialogue Box appears and there you need to type the variable name as PATH and for Value you need to paste the \bin directory of Java development kit (jdk 1.x.xx). shown in fig 1.3.
fig 1.3 New User Variable
STEP 5: Now click on Ok and run Command .
STEP 6: In command you need to type javac which output like in fig 1.4
fig. 1.4 javac in command
STEP 7: If your output gives like fig.1.4 then you are able to compile your java source code by following ways
Also I need to tell dat the we can set CLASSPATH at ENVIRONMENT VARIABLES via DOS for compiling java file;
Here are some steps for windows:
> Go to Command Prompt
> type : set JAVA_HOME=directory(path)_of_your_jdk (as on fig 1.5)
fig 1.5
>now type : set CLASSPATH=%JAVA_HOME%\bin.(as on fig 1.6)
fig 1.6
>Also you need to set CLASSPATH of your JAVA LIB(library).
>Type : set CLASSPATH=%JAVA_HOME%\lib (for library of java)
Testing either the compiler path , library is correct or not.
>Type : echo %JAVA_HOME% (displays the path of Java installed)
>Type : echo %CLASSPATH% (displays the path of your java lib, java compiler as well)
If every thing goes alright then compile java file through following ways via Command at DOS:
For eg: To compile HelloWorld.java
Type : javac HelloWorld.java
Type : java HelloWorld
Outputs:
________________
HelloWorld!!!

Why is there a step entitled ‘To SetUp Class Path’ when it doesn’t do any such thing?
ok i had repaired dare too ….
you can check it out
can’t u see the steps for defining classpath of java
right in Step 1,2,3,4….
Simply terrible.
That is you setting up your PATH. Your windows environment variable PATH has nothing. I repeat nothing to do with your classpath.
And this is why sites like this are rubbish. Because you keep referring to classpath and have obviously know idea what that even is.
Narayan, they are the steps for defining the PATH. Which is different from the CLASSPATH.
If this is an indicationm of the quality of your site I would advise readers to try elsewhere. Such as the Sun documentation for a start.
isn’t this the way of defining path of java
Or should i post addition with other method?
i.e From CLASSPATH via command
ok i’ll also add some posting of CLASSPATH
i know abt dat too…….
svp le jcreator version 4.50 pro comment je peut réaliser des forme est ce qu’il faut un ide et quoi le ide que je fait
