Problem:
Question 1- Create an Alien abstract class. Include at least three protected data members: the number of eyes, the number of legs, and the height. Include a constructor that requires a value for each data field and a toString() method that returns a String containing a complete description of the Alien. Save the file as Alien.java.
Question 2- Create two classes-Martian and Jupiterian-those descend from Alien. Supply each with a constructor that sets the Alien data fields with values you choose. For example, you can decide that a Martian has four eyes but a Jupiterian has only two. Save the files as Martian.java and Jupiterian.java.
Question 3- Create an application that instantiates one Martian and one Jupiterian. Call the toString() method with each object and display the results. Save the application as CreateAliens.java.
