Chapter 8, Problem 4E

Suppose we want to implement a drawing program that creates various shapes using keyboard characters. Implement an abstract base class DrawableShape that knows the center (two integer values) and the color (a string) of the object. Give appropriate accessor methods for the attributes. You should also have a mutator method that moves the object by a given amount.

Define a class in java representing physical elements (like hydrogen, helium, lithium,etc.). Elements have a name, a symbol, an integer atomic number, and an atomicweight (which may be fractional). Your class should have a constructor that setsall the properties, and a toString method that prints each element as a nicelyformatted String. Write accessors and mutators for each field if you think it isappropriate to do so (ask yourself if the field should be changeable). Update yourmain method to create and print 10 unique elements.
Need help on java homework assignment, It says Create a class Vehicle. A Vehicle has a single instance variable of type String named "vehicleType" that describes the vehicle. It has an abstract method getTires that takes no parameters and returns an ArrayList<Tire> object that describes each Tire of the vehicle. A Tire class has been provided. Vehicle has a single constructor that takes the vehicle type as a parameter.Create a class Bicycle that extends Vehicle that has two Tires, both of type "skinny". Bicycle should have a single default constructor.Create a class Dragster that extends Vehicle and has four Tires, two of type "slick" and two of type "medium". Dragster should have a single default constructor.Write a tester program to test Bicycle and Dragster objects. Use declarations such as    Vehicle b = new Bicycle();in your tester.   Here is the code provided : public class Tire {    private String size;    public Tire(String siz) {       size = siz;   }    public String…
