New to Java, Need Help!

Andrew

hello friends, I am a java beginner. I have installed JDK 1.6 successfully. But I am unable to run any program because of this error:

E:\Java>javac helloworld.java
'javac' is not recognized as an internal or external command, operable program or batch file.

Please reply ASAP .....

The new article posted today shows how to set the path permanently. I suggest using something more like what Vulpes suggests. There are many alternatives.

You need to execute the setpath command before compiling java file. http://www.google.co.in/search?sourceid=chrome&ie=UTF-8&q=setpath+in+java

A good practice when you're using any programming language from the command line is to write yourself a batch file to set up the environment correctly, when you start a new command prompt session.

Here, you could create this batch file (javasetup.bat), using notepad, in your C:\users\Andrew folder:

@echo off
path=%path%;C:\jdk6\bin
cd e:\java
e:

This assumes, of course, that you've installed the JDK in your c:\jdk6 folder.

When you start a new command session prompt, you just then need to type 'javasetup' and you're all set to create and compile your Java programs.

hi,

have you set your pathname and class name correctly?..
go to your java's bin folder.
copy its path(eg it may look like C:\jdk1.3\bin or if you have a special folder myjava in your bin then it may look like C:\jdk1.3\bin\myjava)
go to windows command prompt(there it may be written as C:\Documents and Settings\Administrator> , whatever type cd\
press enter.it will be changed to C:\, type cd paste your path and press enter. now your path has been set there(temporary setting)
now you can compile it.

another one is whatever program you try make sure that it is stored in bin of your java and also it is STORED AS A JAVA FILE NOT TEXT FILE.
mostly you type the program in notepad. then save it there. but mostly it is saved as text file.
this can be avoided by typing the program in notepad save it somewhere and from there give save as to bin folder. dont forget to give the extension java and file type as all files.
also make sure that your class name and program name is the same and java is CASE SENSITIVE
