I don't know if I need the code, but whenever I compile something with an inner class, or some sort of "extends," I get this warning message:
I figure the program will run despite the warnings, but I want to get rid of those pesky things. I found some instructions for Eclipse, but because of my small hard drive and little memory, it's too big to load, so I have to use the command line. I compile the project by sayingCode:the serializable class <classname> does not declare a static final serialVersionUID field of type long
Code:javac <folder with classes>
