Java: How will JVM optimise the call to a void and empty function?

Question

Let\'s imagine we have the following classes:

public class Message extends Object {}

public class Logger implements ILogger {
 public void log(Message m) {/         


        

Answer 1

The Server JIT will certainly inline and eventually eliminate the code altogether if you make the reference final: final ILogger l = new Logger(); In a modern JVM most of the optimization is performed by the JIT.
