Answer 1

you can't assign a value of any attributes of class. you can do this to class example:
objectName = new className();
objectName.arrayName[elementIndex] = value

Answer 2

all these information is written in the lessons. If sth is not written in lessons you can find it in documentation on microsoft website or stackExchange
