315: Mainline

In Segment 295 and Segment 300, you learned that you can use this and super in a constructor, without field selection operators and method names, to call constructors. When so used, the this or super call must be the first call in the constructor. When super is used, the constructor called is the one defined in the direct superclass.

In this chapter, you learned that you can use this and super in methods, with field selection operators and method names, to call methods. Such calls can appear anywhere. When super is used, the method called is the first one encountered in the subclass–superclass chain.
