Hello,
I just installed the Java SDK and I was wondering, how do I compile my *.java file using command line?
Thanks for your help,
Daniel

First month into studying Java, and I am already answering questions of other newbies... lol...
In order to compile from the command line, you have to access the folder where your .java file is. Let's say it is in "MyJavaCourse" folder on drive c, you would have to move to that folder with a DOS command "cd" and get to this:
c:\MyJavaCourse
after which you use the compile command:
c:\MyJavaCourse javac firstjavaprogram.java
and then you would get one of the following two things:
a)a newly created .class file (firstjavaprogram.class), meaning succesfull compiling, or;
b)some typical "self-explanatory" Microsoft- style error message about someone not being able to compile because of bla... in which case you should visit a dark corner on your Windows machine in the Control Panel cave (look for enviromental variable in the "System" black hole)and set the CLASSPATH variable... keep coming back at the ranch for more answers, this is a great forum...
