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

Example $1$

$1->$ Calls constructor from Star class $($which actually calls constructor from $\_\_\_$A$\_\_\_$ Class$)$ and creates new RedGiant object

$2->$ Calls setMass from the $\_\_\_$B$\_\_\_$ Class which the RedGiant object inherited and sets the instance variable mass $($inherited from the Star Class$)$ to $1\mathrm{.}0$

$3->$ Calls getMass from the $\_\_\_$C$\_\_\_$ Class which the RedGiant object inherited and prints the value of the mass that was set in line $2(1\mathrm{.}0).$

$4->$ Calls doubleMass from the $\_\_\_$D$\_\_\_$ Class

public class Star $\{$

private double mass;

public void setMass $($double mass$)\{$

this.mass $=$ mass;

$\}$

pubic double getMass $()\{$

return this.mass;

$\}$

private double doubleMass $()\{$

return this.mass$*2$;

$\}$

public class RedGiant extends Star $\{$
