cannot find symbol, java, classloader

Question

Currently doing a typestate project and I am having problems with importing the List class. When I try to compile the class it throws an error in command line saying cannot find

Answer 1

You are using the interface List but you didn't import it, it says that It can not find symbol java.lang.List because it is trying to search this class in the default java.lang package, add the import java.util.List and you are not going to have problems
