I am just getting started with java for 21 days book. the very first program "hello world"
is causing me problems. I successfully create HelloWorld.class but when I run "java HelloWorld"
i get in return "Can't find class HelloWorld"

Here is the program
class HelloWorld
public static void main (String args[ ]) {
System.out.println("Hello World!");
}
}


any ideas?

I'm not fully familiar with the command line commands, but you'll have to compile your
HelloWorld.java code into HelloWorld.class. I believe (actually, I'm pretty sure) you use
javac.exe. So try going to the directory with the source code and type
"c:\java\bin\javac HelloWorld" and then, in that same dir "c:\java\bin\java HelloWorld".
Of course, you'll have to substitute the proper path name to the javac.exe and java.exe files.

If you still have problems executing "java HelloWorld" from the directory where the
HelloWorld.class files exists, try adding the classpath setting.

For instance, if your class files reside in /home/mystuff/java, then try
"java -classpath /home/mystuff/java HelloWorld" (for Unix systems) or
"java -classpath c:\home\mystuff\java HelloWorld" (for Windows systems).
