Exercises 02 (working with access, accessors and mutation Hero2.java): In this task, you will modify your Hero class from part 1 to create the class Hero2 (see UML below). To achieve this, you will need to: 1. copy over your code for each of the constructors from part 1 (Hero.java) 2. modify the "access" properties for class variables as per the UML diagram below Hero2 - x : double y : double - width : double - height : double - body : Color - engines : Color Hero 2 + Hero20 + Hero2(double x, double y) + Hero2(double x, double y, Color body, Color engines) + toString0 : String + getXO : double + getYO : double + setX(double x) : void + setY(double y) : void + setBody(Color c) : void + setEngines(Color c): void Color 3. create the relevant accessors and mutators for the Hero2 class each accessor should return the value of the associated field each mutator should use its argument to set the value of the associated field a. b. 4. Use the main method in a client application (Hero2Client java) to test the above by: constructing the same Hero objects as you did in part 1 (as Hero2 objects) (you will need to use the mutators for shooter2 and shooter3) a. b. print out all Hero2 objects using toString0
