Question

I have finals coming up.

(Tony Gaddis Starting out with Java)

Given that Chapter 6 was on classes.

Chapter 7 was on Arrays and the ArrayList Class.

We were told to know :

surface are and volume of a cylinder

Could you give me some pseudo code that uses Arrays, array list, incorporates Classes

I dont need any code, just ideas of what a test question would consist given those conditions!

Thanks!

we have covered

Decision Structure

loops

methods

classes , arrays and arraylist Heave emphasis on these....

last test we were to make methods to area of triangle and such

Thanks for all your help!

Since you have to calculate surface area and volume of cylinder
then you can store many Cylinder information in ArrayList

Just create a Cylinder class:

   class Cylinder{
       double height;
       double radius;
   }

Now, you can define calculateArea() and calculateVolume() methods inside Cylinder class:

       class Cylinder{
       double height;
       double radius;

       double calculateVolume(){
           //
       }

       double calculateArea(){
           //
       }
   }

Now, you can create another class that interact with user to take Cylinder information:

class Test{

main(){

// create ArrayList to store Cylinder Object
ArrayList<Cylinder> list = new ArrayList<>();

// Now you can have a while loop to take cylinder information about cylinder till user want

while(//user condition to stop loop){

// get information of a Cylinder

create a object of Cylinder

add this object in arraylist

list.add(cylinder);
}

// now you can iterate array list and show area and volume of each Cylinder

       for(Cylinder c : list){
           c.calculateVolume();
           c.calculateArea()
       }

}
}
