You probably have some other "Date" class imported somewhere (or you have a Date class in you package, which does not need to be imported). With "import java.util.*" you are using the "other" Date. In this case it's best to explicitly specify java.util.Date in the code.

Or better, try to avoid naming your classes "Date".

The line:

import java.util.*

doesn't just import Scanner. It brings everything from the java.util namespace into your imports.

You'll have AbstractCollection, Collection, Comparator, Deque, Enumeration, ... all the way to Vector and WeakHashMap.

Write what you mean and mean what you write. You aren't intending to bring everything in the java.util package into your namespace. You want to bring one class. Bringing in too much, especially in this day of easily adding imports to a class and collapsing all them at the top is unnecessary.

^{In days of old, long before IDEs for Java were commonplace, I'll certainly admit to doing an import of * into my class. It was easier to write the import in vi, and it saved a few back and forth to the compiles to say "oh, I don't have java.awt.Color in here, but I've already got java.awt.Button and java.awt.GridBagLayout and java.awt.GridBigConstraints and... frack... I'll just do import java.awt.* and be done with it" Those were in the days of old. You don't do that anymore, especially for one class.}

Furthermore, most IDEs will automatically convert the import of java.util.* into what you want, unless you actually are importing everything in the package (sometimes seen with "I'm importing all the my.package.exceptions that I wrote" or "I'm importing all the my.package.dtos that I wrote").
