Can someone help me code the following project in JAVA? I'm a little confused, and would appreciate slashes to help me follow along as you go through the code.

Design a 3-level hierarchy of entities of your choosing. An example is: (if you want to use this to help me, go ahead)

All classes in the upper two levels should be abstract.

The uppermost class should include:

• Minimum 2 data fields

• Accessor methods for data fields

• A constructor to initialize the data fields

• Minimum 1 abstract method

The mid-level classes should include at least one constructor.

The lowest subclasses should include at least one constructor and implement the abstract method from the highest class.

Please write a minimum of 6 classes (1 upper, 2 mid, 3 lower).

**You do NOT have to write a driver for this lab.

Here is an example of what the uppermost class in the hierarchy could look like:

Animal Mammal Crustacean Rabbit Kangaroo Crab Barnacle
