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.

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.

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 = false; material = wood; Finally, repeat your print statement you wrote earlier to print out what the chair looks like. Tip: When taking in parameters to a constructor, you may want to do have the variables used in the constructor header be different words from the attributes in the Chair class. When dealing with rolling/not rolling you may want to use an IF statement with different print statements.

Sample output: You are about to create a chair. How many legs does your chair have: 8 Is your chair rolling (true/false): true What is your chair made of: plastic Your chair has 8 legs, is rolling, and is made of plastic. This program is going to change that. Your chair has 4 legs, is not rolling, and is made of wood.
