Is it possible to write an electronic diary in java from scratch?

Question

Java

Well, as I said, can this be done entirely in Java? What I mean by an electronic diary: this is a Database, grades and lists of students, 2 or 3 privilege accesses (1 - student, 2 - teacher, 3 - admin), synchronization between the application and the site (the site is also in java). Is it possible to do all this in one Java?

Answer 1

Yes.
