I really do not understand the "property" and the "setter". The "property" makes the attribute read-only, but the "setter" makes the attribute mutable. So if we want to use "property", why we need to introduce the "setter".

just asking. in C++, why do we need to define signed & unsigned integer? why don't we always use signed? it's better. we can freely assign plus and minus. so what's the catch of using unsigned?

How can I add an item at the end of the array? The most easy way (arr [5]=8) returns "out of range", and I suppose it's because first I instantiate it as "int [] arr=new int[5]", so it's out of the range. Can I amplify that range?
