1 00:00:00,160 --> 00:00:02,780 Now that we've discussed how to choose a pattern. Imagine that 2 00:00:02,780 --> 00:00:05,210 you have to write a class that can have only one 3 00:00:05,210 --> 00:00:08,090 instance. So to satisfy this requirement, I would like for you 4 00:00:08,090 --> 00:00:10,720 to pick one of the design patterns that we discussed in 5 00:00:10,720 --> 00:00:14,580 this lesson, and write the code here that satisfies that requirement. 6 00:00:14,580 --> 00:00:16,270 And when you write the code, please make sure that your 7 00:00:16,270 --> 00:00:21,140 class has only one method, without counting possible constructors, and that 8 00:00:21,140 --> 00:00:25,120 the class is called Singleton. And write your class right here.
