Question

When answering this question, can you please specify what you name your files? Thank you!

Write a Java application, and an additional class to represent some real-world entity.

Keep in mind that a class is a model in code of something real or imagined, which has attributes (member variables) and behaviors (member methods).

The class will:

a. Create a total of 5 member variables for the class, selecting the appropriate data types for each field. For example, a class to represent a lamp might include color, price, height, numBulbs, batteryOperated. Each of these 5 variables need a data type.

b. Include at least three different constructor methods, in addition to the default constructor (0 argument constructor). The constructor is a function (method) which allocates memory and initialized the member variables specified in (a.).

c. Include getters/setters for to serve as as mutators and accessors for each variable. Name these appropriately such as setColor & getColor, setPrice & getPrice, setHeight & getHeight, setNumBulbs and getNumBulbs, and setBatteryOperated & getBatteryOperated.

d. Create a member function showValues() to display the values of an object in a formatted manner.

e. Create at least 2 other member functions (methods) for the class that will perform some operation on the data (i.e. calculations or additional report/display of output). For example, turnLampOn, changeBulb, etc.

The Java application class (with a main method) will:

a. Instantiate at least three objects (using each of the constructors at least once) with your program. Note: Set the remaining data with the mutator methods.

b. Store the data from the individual objects into an ArrayList (or some other dynamic data structure of objects.

c. Utilize the showValues() method and each of the two methods on each of your objects to demonstrate their use. Required Output: Generate output samples demonstrating all of your member functions, adequately testing them and showing their functionality (i.e. inputting values, outputting values (displaying them), performing calculations, etc.).
