Join Ketkee Aryamane for an in-depth discussion in this video Visibility settings: Final, static, and transient fields, part of Java EE 8: JSON-B.
- [Instructor] Okay, next one is final fields.…Okay, how do final fields look like…in JSON serialization?…Let's go there and make sure we go right up…and create a final variable.…So I'm gonna say "public final", "string",…and let's declare the user type.…It's a final variable, which is why…I have used that naming convention.…The convention is the always…the variable name is going to be all in uppercase, right?…All characters in uppercase.…
So let's give it a value, I'll say, "admin".…Let's say this user is the admin tag.…Okay, I'm setting a value right there…because it's a final field.…Right? The Java concept.…Now let's come down, and let's see that…when I try to serialize the user object,…whether that final field shows up or not.…So let's go ahead and run this...…Yes it does.…So final fields totally work…for JSON Binding API.…That's good. Next is static fields.…So let's say I want to put a static field right up there,…I want to go ahead and count…the number of users in my system.…
I will make a field, let's say,…"public static...…
