    Hey,

    You can read more about it here: http://stackoverflow.com/questions/1...pile-java-code

    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"
