How relevant are these books?

Question

Java

I have several old paperback books. Can you tell me whether they are relevant now or is it better to read something more modern in electronic form?
Books:
1) Perrone P.D. et al. "Building Enterprise Systems with J2EE" . Year of publication: 2001.
2) K. J. Date "Introduction to database systems" . Year of publication: 2006.
3) Viktor Kasyanov, Vladimir Evstigneev "Graphs in programming: processing, visualization .... Year of publication: 2003.

Answer 1

It seems that 2 and 3 are theoretical, they can be read, for example, as an introduction to the field. The first one is definitely outdated, 14 years have passed, imagine how the language and tools have changed during this time.
