Important question

Because the assignment operator '=' assigns the value on the right to the variable on the left. variable = value <-this assigns value to variable value = variable <- this will throw an exception and crash the program. Just like you declare an int and assign it a value: int num = 8; <- num varaible now stores 8 8 = num; <- crashes program Woman.husand is a man object variable (see it declared on line 21) that will store a man object value.

I think it is logical if you think of it as a question, as in a woman's husband is a man. Futher more man in an object which the husband variable now has a reference to. I hope this is helpful.
