Assuming that we want to compare two computers we would first need a way to rate a computer.
We are going to expand on our Computer Class by adding a method to give a rating to a computer based on a number of factors.
The data within each computer that will come into play when we rate a computer is:
int speed;
int diskspace;
int monitor;
boolean floppy;
boolean dvd;
The method will return an int, it will take no parameters, and we will call it getRating.
Points are calculated as follows.
Speed @ 1 pt per Mhz
Diskspace @ 10 pts per GB
Monitor @ 20 pts per diagonal inch
100 pts for a DVD
10 pts for a floppy
Here is the code----
int getRating() {
int rating;
rating = speed;
rating = rating + diskspace * 10;
rating = rating + monitor * 20;
if(dvd) {
rating += 100
}
if(floppy) {
rating += 10;
}
return rating;
}

Today, we will be learning how to get a Mac address off of your machine and that Java's memory management
does not work on external processes run by the operating system even if they were invoked by a call from
within a running Java class. |

Object-oriented Programming in Java |

I see old-fashioned procedural programming concepts being used in object-oriented languages. I also see dead people, they're everywhere. As a freelance programmer specializing in Java I often find myself working with legacy code that is not only poorly documented but often contains three to four times as many lines of code as is necessary to accomplish the task. It also amazes me how often I see old-fashioned procedural programming concepts being used in spite of the fact that the programmer is writing in a true object-oriented language. |
