$3\mathrm{.}18$ LAB: Set basIcS

Java

Given the user inputs, complete a program that does the following tasks:

Define a set, fruits, containing the user inputs: my$\_$fruit$1,$ my$\_$fruit$2,$ and my$\_$fruit$3.$

Add the user inputs, your$\_$fruit$1$ and your$\_$fruit$2,$ to fruits.

Add the user input, their$\_$fruit, to fruits.

Add your$\_$fruit$1$ to fruits.

Remove my$\_$fruit$1$ from fruits.

Observe the output of each print statement carefully to understand what was done by each task of the program.

Note: For testing purposes, sets are printed using sorted$()$ for comparison, as in the book's examples.

Ex: If the input is:

apple

peach

lemon

apple

pear

plum

the output is:

$[$ 'apple', 'lemon', 'peach'$]$

$[\text{'}$apple$\text{'},$ 'lemon', 'peach', 'pear'$]$

$[\text{'}$apple$\text{'},$ 'lemon', 'peach', 'pear', 'plum'$]$

$[\text{'}$apple$\text{'},$ 'lemon', 'peach', 'pear', 'plum'$]$

$[\text{'}$lemon$\text{'},$ 'peach', 'pear', 'plum'$]10\mathrm{.}8$ LAB: Instrument information $($derived classes$)$

Given the base class Instrument, define a derived class StringInstrument for string instruments with a constructor that

initializes the attributes of the Instrument class as well as new attributes of the following types

integer to store the number of strings

integer to store the number of frets

boolean to store whether the instrument is bowed

Ex$.$ If the input is:

Drums

Zildjian

$2015$

$2500$

Guitar

Gibson

$2002$

$1200$

$6$

$19$

False

the output is:

Name: Drums

Manufacturer: Zildjian

Year built: $2015$

Cost: $2500$

Instrument Information:

Name: Guitar

Manufacturer: Gibson

Year built: $2002$

Cost: $1200$
