How to fix java intermittent lags?

Question

The same code in my project has different execution duration for the same input parameters, it varies from 1ms to 30ms.

private void link(Array values, Area area){
   values.add(area);
   Array<Area> children = area.getChildren();
   for (int i=0; i<children.size; i++){
       Area child = children.get(i);
       link(values, child);
   }
}

This lags are inappropriate. Can I fix them?

Answer 1

Intermittent lags are caused by garbage collection.
