why value of a is not overiding??

Question

class see
int a;
main ()
see x = new see();
see y = new see();
x.a= 4;
y.a=5;

syso(x.a). ==4
syso(y.a ) ==5

why variable a have two values?

Answer 1

You can see a class as a factory that produces objects.
Your class See might produce glasses with the attribute a, which could be a int number that stands for the color or something.
No you create two objects, glasses x and glasses y. Two different glasses. Each of that object can have it's own value for the color which is stored in the attribute a.
Your object x can be blue (x.a) and your object y can be red (y.a). Although their type (class See) is the same.
And if you paint your x object black, your y object still remains red.
Hope this example can help you.

Answer 2

No, imagine it like: a is for color. You can produce with which color value you like, blue or red. And you can change it after production (under certain circumstances - attribute must be accessible somehow).

Answer 3

Just what I said ^^
It may have the color *whatever*. And another object can have another color. Do you agree that cars can have different colors although they are produced in the same factory?

Answer 4

Replace object by attribute and you're on the right way ;)

Answer 5

no I don't understand, let's say a is for blue color and see produce class then two blue glass will be created
