What is the best way to implement a particle system in Java?

Question

Java

Using the LibGDX framework, I made a lot of particles through Array according to the principle
www.libgdx.ru/2013/09/simple-game.html
However, on weak devices, drawdowns occur every couple of seconds due to the garbage collector.

We need a different particle algorithm in order to initialize the array only once at the start of the game, and then twist it.
Here I am interested in the algorithm how to manage such an array.

Answer 1

Regular means of libgdx ?
In general, libgdx has special recommendations and implementations of basic things for working with memory, incl. special pools.

Answer 2

Where did garbage collection come from? Are you destroying old particles and creating new ones? Use the pool - we hide the old ones partially, we get the new ones from the pool and turn them on.
