As an example For those who have this: (Hah, get it? this

In the above case in point, We've got handed eight as a worth for the constructor. On the other hand, we've been obtaining 0 as an output. This is as the Java compiler gets puzzled due to the ambiguity in names involving occasion the variable as well as the parameter.
