Question

I am trying to compile with javac on Snow Leopard through the command line. I have Xcode installed. I am just using a simple Hello World file, it works in Eclipse but I can’t get it to work using javac.
javac -version returns javac 1.6.0_17

HelloWorld.java

public class HelloWorld
{
   public static void main(String[] args)
   {
 String message = "Welcome to Java!";
        System.out.println(message);
   }
}

I type: javac HelloWorld.java

and get the following error.

HelloWorld.java:1: class, interface, or enum expected
public class HelloWorld 
^
1 error

and…

javac -cp . HelloWorld.java

returns the same.

echo $CLASSPATH just returns blank.

Thanks for the help.

Answer 1

Are you using UTF-8 perhaps, with a byte order mark at the start of the file? Perhaps that’s confusing javac?

Have a look at the file with a hex editor to see what it looks like.
