Counter.java

why the fuck do retards have to invent a goddamned class just to use a goddamned integer? have people no shame?

Counter.java

/**

* a specific value, incremented, and cleared.

int myCount;

* @param init is the initial value of the counter

public Counter(int init)
{
myCount = init;
}

/**

Yes, no.

There's a difference between using abstraction because you understand what it abstracts and how it can be useful and what the limitations are, and using it because someone told you to.

It's like giving a kid a calculator and telling her ("maths is hard!") that it'll solve all her homework maths problems. Sure it works for the simple stuff, and she'll feel like she won't ever have to learn arithmetic, but what if the result overflows? Even worse, what if it produces subtly wrong answers? Someone who doesn't know how arithmetic works can be easily made to believe that 2+2=5, 1+4=7, or whatever the calculator says, in the same way that someone who doesn't understand software can be persuaded to believe anything about how computers work. A calculator is a (very leaky) abstraction, just like software.

Thankfully there are sane people teaching maths (http://www.bbc.com/news/education-20259382 ), but unfortunately this hasn't been true for computer science.

You might do better to copy the useful posts only, and leave out the /pol/ idiots.
