This shows that basically you shouldn't be even trying to run the code yet - it doesn't compile. If you're using Eclipse, you should have received a warning dialog when you tried to run the code, explaining that it didn't compile cleanly - at that point the right thing to do is pretty much always to not run it. If you're using a different IDE it may not have popped up a dialog box, but you should still be able to see an error in whatever error list view is available.
Within the getColorSchemes
method, you're trying to refer to a variable called schemes
which apparently hasn't been declared anywhere. We can't say any more than that without seeing the code, but it may well be as simple as there being a variable called colorSchemes
instead of schemes
, or something similar.
