You can open an area of the screen(view), leave it open in the bottom-left corner or wherever you want, and then you cansee what proposals the system has for you in regard to creating missing things automaticallyor other types of refactoring (Figure 1.14).Figure 1.14 Quick Assist ViewYou won’t need to have such a screen area open once you’re used to all the thingsABAP in Eclipse can do for you, but at the start this is very helpful to remind you thatnot everything has to be done manually any longer.1.2.4 Extracting a MethodProgramming is a battle against the code ro tting over time, and part of the antifragileprinciple discussed in the book’s introduction is that programmers mustconstantly look for ways to make their programs resistant to the ever-increasingsea of changes those programs must undergo.
