Where are those symbols (classes ???) defined? The compiler can not find their definition.
Please post the full text of the error message that shows the source line. For example:
TestCode12.java:566: error: cannot find symbol
AerryList<NoClass> test;
^
symbol: class AerryList
location: class TestCode12
TestCode12.java:566: error: cannot find symbol
AerryList<NoClass> test;
^
symbol: class NoClass
location: class TestCode12
Without seeing the code I also can not see where those symbols are defined.
