Is there a big difference in writing a java application for desktop and web?

Question

Java

Suppose you wrote a desktop program in swing, does the set of code for the same program differ greatly only under the web? I hope I explained clearly. Thank you all dear!

Answer 1

Completely different skills.

Answer 2

depending on which piece to take
server-side, in theory, the same
ui is generally the same - yes, there is a difference

Answer 3

Yes, the difference is usually big. But there are frameworks that will facilitate the transition to the WEB, and work on similar principles. I recommend looking at Apache Wicklet https://wicket.apache.org/ and Vaadin - https://vaadin.com/
