can’t seem to figure out why my program won’t run.  I am not even sure if I have the Animal newInstance method

written correctly in my Animal class.  I am new to Java and am struggling with this.  I have attached what I have done so far.  Here is my Mammal class (since I couldn’t attach it). Can you help with cleaning up my code so that it will run?  And help me with the Test class? I have not been able to figure out how to do that.
