In Java is there a performance difference between referencing a field through getter versus through a variable?

Question

Is there any differences between doing

Field field = something.getSomethingElse().getField();
if (field == 0) {
//do something    
}
somelist.add(field);
         


        

Answer 1

There is a performance penalty ( which may be so small it is negligible ) Yet, the JVM may inline this and all the calls to improve the performance.

It would be better if you leave it the second way.
