Those annoying Java warnings...

Tux_in_Redhat · #1 1st February 2007, 06:47 PM

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:

Code:

the serializable class <classname> does not declare a static final serialVersionUID field of type long

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 saying

Code:

javac <folder with classes>

Try

Code:

javac -nowarn blah

You might not want the disabling of all warnings though.

I suppose the program will run just fine without the warnings right?
My java libraries are pretty sparse anyway: I don't have any exception classes, or the applet class, or basically any helpful class

Eclipse generates this line of code automatically for each new class, always the same:

Code:

private static final long serialVersionUID = 1L;

This will get rid of the warnings, too..
