thats HelloJavaWorld.java

{
public static void main(String args[])

System.out.println("Hello Java World");
}
}

Hey,

But basically, it has to do with how the HelloJavaWorld.java was encoded (Text-Wise), what did you utilize to make the java file?

I'd recommend you an IDE or a text-editor like Notepad++ and ensure the encoding is either "UTF without BOM" or "ANSI"

I'm glad that helped, Straight UTF-8 would not of worked (I believe), it would of need to be "UTF without BOM"
