Task 1: Docking We would like to define a universal interface for our equipment and drones for docking. This way, when we develop new vehicles or stations we can implement the universal interface and know that it will behave in the same way. Instructions Create a Java interface called Dockable which has the following methods specified: a method called canDock that takes no parameters and returns a boolean a method called dock that takes a Drone as a parameter and returns an integer Task 2: Drones and Stations Now we want to test our docking interface, but first we want to define an abstract class for our drones from which we will model all of our designs after. Instructions Create an abstract class called Drone that has the following properties: a private attribute called name of type String a private attribute called weight of type double appropriate getters/setters for the attributes an abstract method called printInfo an abstract method called calculateTotalWeight that…

Need an example of this format in java programming in eclipse Create a class 1. Define instance data fields 2. Define a constant properly; use the constant when needed 3. Define a constructor that receives parameters for instance data 4. Generate get and set methods for instance data (even though some methods may not be used) 5. Define 4 other methods • method one will not receive any parameters, but will return a value to the driver program • method two will receive one parameter, and will also return a value to driver program • method three will receive one parameter, and will also return a value to driver program • method four will receive 3 parameters from driver program and will be responsible for displaying all output B. Create a driver program 1. Instantiate objects passing specific data to the programmer written constructor 2. Call each of 3 methods, for each instantiated object, passing any required arguments, and saving any values being returned in a variable 3. Call the 4th…
