Is it possible to set a default behaviour for custom (non-native) methods/functions in Java?

For example, I would like to change the default "Function" to do a System.out.println("message") whenever called.

So, when a custom method/function is being created:

public String testMethod()
{
   //custom code
}

it should execute the newly added default behaviour (in this case the system output), before the custom code is run.

Even if this would be a bad excercise, is it possible? Maybe by extending the function class or something?
