Which 'ArrayList' are you using?

What Java version are you using?

How do you have your Eclipse project settings set for Java compilation?

And what is Eclipse using?

Java conventions call for the use of all-uppercase variable names only 
for constant variables, and likewise reserve the use of underscores 
in names for that case.

Best practice usually is to type the variable to the interface.

You know if you only give us half the data we can only provide half an 
answer, right?

In this case, set your Eclipse preferences to use the correct Java syntax.
