Putting your own files in the bin folder? Never do that. The bin folder is for Java (JDK/JRE) to store its executable files. Navigate elsewhere and create a folder, in "my documents" or "C" or somewhere, for your Java files. Make sure to navigate to the folder where the Java files live before using the command prompt.
