Your code failed to compile correctly against the reference tests. This is most likely because you have not named your class(es) as required in the assignment, have failed to provide one or more required methods, or have failed to use the required signature for a method. Failure to follow these constraints will prevent the proper assessment of your solution and your tests. The following specific error(s) were discovered while compiling reference tests against your submission: Project/Proj6tests.java:1146: error: incompatible types: ArrayList cannot be converted to EllipsoidList E11ipsoidtist actual = list. readfile(filenamee); Project/Proj6tests.java:1161: error: incompatible types: ArrayList cannot be converted to EllipsoidList E1lipsoidtist actual = list. readfile(filename1); Project/Proj6tests.java:1176: error: incompatible types: ArrayList cannot be converted to E11ipsoidList Ellipsoidtist actual = list.readfile(serectFilename); 3 errors
