You will create a Java class to define something ... anything. It is purely up to you to decide what you want to create. The only limitation is that you cannot use the classes created in lecture. For example, we developed a Square class in lecture. So, you cannot create a Square class for this lab. Also, you cannot create a Hedgehog class because that is being used as the example for this assignment. You will have two files. One file is Lab7.java. That file will contain your main method that will create an array of at least three objects from your class and you will initialize them as described in this assignment. Then, you will print the descriptions of the objects using the toString() method. The second file will be your custom class file. The name of this file must match your class name. It will contain a minimum of: Three attributes Three constructors All necessary getters and setters At least one method that performs a calculation A toString method..
