JavaFX destroy or reuse Buttons?

Information:

I have a database table with 200.000 entries.I am using an ArrayList which holds 100 Buttons each time(Each Button has the info from the table entry it matches).

When the right arrow key is pressed the ArrayList is being cleared and the next 100 entries of dataBase table are added(as Buttons).

What i want to say is that every time i search the dataBase or i press left or right keys the ArrayList is cleared and added with 100 new Button.

The Problem

Should i reuse the existing buttons passing different values or just clearing them and creating new ones?

If i create new Buttons it consumes more memory ?If i reuse the same Buttons it doesn't consume extra memory?

It's hard to give a clearly response. You can test your own application for both cases.

First one view difference of memory, like this: 

Runtime.getRuntime().totalMemory() - Runtime.getRuntime().freeMemory();

And test how fast your application will work, in header declare new variable:

Date start = new Date();

In end of app 

new Date() - start;

And you will answer yourself.
