+00:00:00,110 --> 00:00:03,000
+The first scenario is the typical case in which it is
+
+2
+00:00:03,000 --> 00:00:07,040
+recommended to use the extract method refactoring, when there is duplicated code
+
+3
+00:00:07,040 --> 00:00:09,190
+in two or more methods and we want to take this
+
+4
+00:00:09,190 --> 00:00:12,420
+code and factor is out, and basically have the two methods called
+
+5
+00:00:12,420 --> 00:00:14,960
+a third method, which is the one we create using the
+
+6
+00:00:14,960 --> 00:00:18,060
+refactoring. When a class is too large, normally we don't want to
+
+7
+00:00:18,060 --> 00:00:21,330
+apply the extract. Extract method. Instead, in this cases, it is
+
+8
+00:00:21,330 --> 00:00:22,900
+usually more appropriate to use the
+
+9
+00:00:22,900 --> 00:00:26,420
+extract class or extract subclass refactorings.
+
+10
+00:00:26,420 --> 00:00:29,750
+Analogously, when the names of two classes are too similar, extracting a
+
+11
+00:00:29,750 --> 00:00:32,729
+method will normally not help much. And all we need to do
+
+12
+00:00:32,729 --> 00:00:35,810
+in case having too similar names is actually a problem. Is to
+
+13
+00:00:35,810 --> 00:00:39,600
+rename one of the two classes, or both, if we wish. Finally,
+
+14
+00:00:39,600 --> 00:00:42,530
+it is definitely appropriate to apply the extract method of refactoring in
+
+15
+00:00:42,530 --> 00:00:45,900
+cases in which a method is highly coupled with a class other
+
+16
+00:00:45,900 --> 00:00:48,330
+than the one where it is defined. In this case, which we
+
+17
+00:00:48,330 --> 00:00:51,740
+will discuss also later in the lesson, the extract method of refactoring
+
+18
+00:00:51,740 --> 00:00:55,710
+allows us to extract part of the metal to With the other class.
+
+19
+00:00:55,710 --> 00:00:58,690
+Then we can take the matter that we just extracted and move it
+
+20
+00:00:58,690 --> 00:01:01,880
+to the class where it actually belongs. So the extract method is one
+
+21
+00:01:01,880 --> 00:01:05,560
+of the two refactorings that it is appropriate to apply in these cases.
