$1.$ Create a class Student and another class Instructor. $[$Details areunimportant at this stage, and yes, this will be very poor O$-$Odesign!$].$ Let each class have a single instance variable name thatcontains a full name. Class Student is shown at right. $[$Remember touse Eclipse source shortcuts to create these classes very quickly!$]$Suppose we want to require a behavior that displays a role as part ofthe name. For example:Stephen Weissman, instructorSusan Holly, student$2.$ Create an interface RoleDisplayable to require a void method displayNameAndRole$()$a$.$ Code a default method for displayNameAndRole$()$ that makes all Student instances displaythe name with $,$ Student after the name.b$.$ Important: if its not a Student, lets make the default method do nothing. $[$Maybe notgreat design, but it will make this lab more interesting!$]$ How will you do this??c$.$ Also important: if you try to invoke getName$()$ from your default method, youll get acompile error! $[$Remember static and dynamic types? getName$()$ is in the dynamic typeStudent!$]$ To solve this problem, well need to add a cast before thedot and method call something like this: $(($Student$)$ this$)\mathrm{.}2.$ Make class Student implement RoleDisplayable.
