Lab13A: A Tale of Two Classes When teaching objects often you may hear the example "a chair is an object". Well for this lab, we are going to use this example. Create a class called "Chair", this is going to be a class which can create "Chair" objects. Also create a separate class to drive the function of Chair, call this driver class "Lab13A". The Driver class will contain the main method you typically make while Chair will not have a main method. Chair class: Variables (Attributes): - notice they are public. This isn't normal, but it's ok for this lab. o public int numOfLegs o public bool/boolean rolling o public String/string material //what is the chair made of //how many legs are on the chair //does it roll or not Using these attributes you can describe most chairs. For example, you might have a wooden chair with 4 legs that does not roll, or you may have a rolling chair made of leather with 5 legs. Now that you know the parameters and their data types you can make a constructor also called Chair; a constructor is a special method that shares its name with the class name, it is responsible for creating the object and starting it off with values for its attributes. It should take in user inputs to provide meaningful info for each attribute. This class isn't going to have any methods, so it should only include a constructor and the attributes. Driver class: This class is going to have a main method and take user input for the attributes for the Chair object. Once you have all that information, create a new object with those variables as parameters. Once you have done that, print out the information about your chair. You can use the name of your Chair object and the dot operator (a period) to print out info about the chair you created. Then, to show you really understand how the dot operator can work. Change the attributes to: numOfLegs = 4; rolling material = wood; = false; %3D Finally, repeat your print statement you wrote earlier to print out what the chair looks like.
