The getResistance$()$method you are given is:

public double getResistance$()\{$

return $0\mathrm{.}0$;

$\}$

$2.$ You need to have it return the actual value of the Resistor's resistance. This should

be an instance $($or state$)$ variable of a Resistor object.

$3.$ You have to declare this instance variable $($it should have private visibility and be of

type double.$)$

$4.$ Of course you also have to choose a name for it$.$ The name should be descriptive of

its meaning. For example, this is a very poor choice $($although it would be legal$)$ :

private double guessWhatIam;

$1.$ However, do not use the name resistance. $($You will soon learn why; you will

also learn how you can use this name but it requires a little bit more Java

knowledge.$)$

$2.$ You have to initialize its value in the constructor and use its value in the

getResistance$()$ method. Note that the constructor is declared:

public Resistor$($double resistance$)\{$

$3.$ The value of the Resistor object to be created is given by the resistance

parameter.

$4.$ You simply have to assign this parameter to whatever name you have chosen as the

object's instance variable.
