I just started learning programming with java as the 1st lang.i tried running this code on cmd prompt but it keeps saying that javac is not an internal or external command,operable program or batch file.

1: public class HelloUser {

2: public static void main(String[] arguments) {

3: String username = System.getProperty("user.name";

4: System.out.println("Hello " + username);

5: }

@ poster, there is no problem with your code, it worked. You only omitted the last brace }; hence:

public class HelloUser {

public static void main(String[] arguments) {

String username = System.getProperty("user.name";

System.out.println("Hello " + username);

}

}

I think your challenge is that you have not set the classpath properly.

first try executing the javac command alone and c the output. if it doesnt show any thing then your class path setup is wrong

I prefer C++ to java. Im an expert in C++.
