Example $2$

For each line of code in the main method, indicate which class the method being executed comes from and the result of executing that method

$1->$ Calls constructor from Bird class which actually calls constructor from $\_\_\_$A$\_\_\_$ Class and creates new Duck object

$2->$ Calls setWeight from the $\_\_\_$B$\_\_\_$ Class which the Duck object inherited and sets the instance variable weight $($inherited from the Bird Class$)$ to $5\mathrm{.}1$

$2->$ Calls doubleWeight from the $\_\_\_$C$\_\_\_$ Class and prints $10\mathrm{.}2$
