- An observer design pattern is one famous design pattern. Explain the purpose, behaviour, pros, cons and example of this design pattern. In the purpose part, make sure to include why we need to incorporate it and what problem it solves. In the example part, Include an example illustration of the observer design pattern using javaarrow_forwardSubject: Software Engineering The objective of a warning system is that it must sound a warning signal if it is approaching an object. The warning system interfaces with a computer vision system which is designed to detect all objects in its field of view, even in extremely low-light conditions. It can identify millions of types of objects, detect the exact location of each object, and interpret each object’s movement (speed and direction). Which of the following is the most logical statement regarding the minimum number of bits required for a C-C-I protocol which supports communication between these systems? a)It maybe an infinity problem requiring an infinite number of test cases. b)Theobjective can be satisfied using 2 or fewer bits, even in extremely low-light conditions. c)Thenumber of bits required can be reduced significantly by doing object categorization. d)It dependson the type of warning signal needed to achieve acceptable Level 2 SA. e)Noneof the above.arrow_forwardStep-by-step software development has benefits over waterfall models.arrow_forward
- The link between cohesion and coupling in software development is not well understood.arrow_forwardCan dynamic programming be used to generate a chain of decisions that depend on one another? The next step(s) are?arrow_forwardCompare the event-driven model to the reactive programming paradigm in software development.arrow_forward
- Software cohesion and coupling are intimately related. How these notions interact is unclear.arrow_forwardIf you were trying to put into effect and execute a computer science program for your school next year and add it to the school’s curriculum to allow better access to learning for students, this action would be best described as? A) implementation B) exposure C) predisposition D) computational artifactarrow_forwardThe relationship that exists between cohesion and coupling, in addition to the dynamic that exists between the two, is something that has always fascinated me in the field of software design.arrow_forward
