Write the FULL j$=$Java code for the following Dumbbell class.

This class represents dumbbells, a concrete class that extends from FreeWeight. It will have:

The following instance variables: gripType $($String$).$

$3-$arg constructor that takes the freeWeightID, weight, and gripType. It will set the

category to $2.$

A compareTo method to allow comparing the class to other FreeWeight $($not just

Dumbbell instances$).$ This is an override to FreeWeight's compareTo, which further

orders elements that the previous definition established as equal. The ordering of

FreeWeight established by this class is the following:

Order first by category, in ascending order

If it has the same category, the instance is guaranteed to be a Dumbbell,

and you can downcast the parameter for the comparisons that cannot

be done against a general FreeWeight

Order second by weight, in ascending order

Order third by gripType, in ascending lexicographical order

Order fourth by freeWeightID, in ascending lexicographical order.

Tip: using the super implementation of compareTo to handle only cases that

have a return value of $0$ in the super implementation is recommended

A toString method with the following format:

$"[$freeWeightID$]$: $[$weight$]$ Ib$.$ dumbbell with $[$gripType$]$ grip" $($without square

brackets$)$

You must use the super implementation of the toString method.

A getter for the instance variable.
