I came to tutorial which teaches you about static and it is kind of good but still he didn't explain some things and I got soooo pissed off !!!!xD

I just cant understand what "return" means and why is he keep telling something about instances !

Code: Select all

namespace Tutorial1
{
    class Program
    {
        static int AddNumbers(int number1, int number2)
        {//Note that we declare with the variable in our method and only use the name assigned
            int result;//this is to make it more clear what we're returning
            result = number1 + number2;
            return result;
        }
        static int GetMedian(int number)
        {
            return (number/2);//Here we're returning number back in half.
            /*we could also have done it like this 
              int finishedproduct;
              finishedproduct = number/2;
              return finishedproduct;
             */
        }
        static int GetNumbers()
        {//This method accepts no arguments, it's just set to get the numbers and pass them back
            string entry;
            int entrytranslated;
            Console.WriteLine("Please enter a number");
            entry = Console.ReadLine();
            Console.WriteLine();
            entrytranslated = int.Parse(entry);
            return entrytranslated;
        }
        static void Main(string[] args)//This is our entry point even if it's below everything else
        {
            int product;
            int numberA, numberB;
            numberA = GetNumbers();//Here you see that we're using the method to assign a variable to numberA
            numberB = GetNumbers();//Again we're using GetNumber to assign a variable
            product = AddNumbers(numberA,numberB);//Now we're using add number, feeding it it's required variables and
            //it's assigning a number to product
            Console.WriteLine("The sum of the numbers is " + product);//Here we're showing the product
            product = GetMedian(product);//now product will be assigned the median using GetMedian
            Console.WriteLine("The median of the two numbers is " + product);
            Console.ReadLine();
        }
    }
}

Here is code so you could see what I am learning :P

class Thing{
}

...

Thing foobar;

An instance is what you make using a class.

For example,

Code: Select all

class Thing{
}

...

Thing foobar;

foobar is an 'instance' of the class Thing

I just CANT get it!!!

Are they important for now ?

if eat() is static, you call it like this:

Code: Select all

Apple.eat();

if eat() is non-static, you first create an Instance of Apple, then call eat() on the instance:

Code: Select all

Apple myApple = new Apple();
myApple.eat();
