Sorry, there was a markup error in my earlier comment. What I meant it to say 
was this:

« If you want people to stop using LinkedList, it will be much more effective 
to get _your favorite tutorial site_ to say "use ArrayList instead of 
LinkedList" instead of trying to remove uses of it from the JDK. »

(I had put the italicized text in angle brackets, which I guess were 
interpreted as malformed markup and so the text was simply dropped.)

I might as well name names here. If you do a web search for "java LinkedList" 
you will get hits on the usual top tutorial sites. One of them is this:

https://www.w3schools.com/java/java_linkedlist.asp

The whole discussion of "ArrayList vs. LinkedList" here is incredibly 
superficial. The summary is this:

> Use an ArrayList for storing and accessing data, and LinkedList to manipulate 
> data.

This sort of statement is a lot more influential in getting Java developers to 
use LinkedList than anything the JDK does. Orders of magnitude more Java 
developers look at these tutorial sites than look at obscure corners of the JDK 
source code. If you want people to stop using LinkedList, it would be better to 
try to get those tutorial sites changed than to try to eradicate LinkedList 
from the JDK.
