Java Part A

Create a class named Rock that acts as a superclass for rock samples collected and catalogued by a natural history museum. The Rock class contains fields for a number of samples $($sampleNumber$),$ a description of the type of rock $($description$),$ and the weight of the rock in grams $($weight$).$

Include a blank, default constructor and an overloaded constructor that accepts parameters for the sample number and weight. The overloaded constructor sets the description value to Unclassified.

Include get methods for each field.

Part B

Create three child classes named IgneousRock, SedimentaryRock, and MetamorphicRock. Include a blank default constructor for each class. Then create overloaded constructors for each class that require parameters for the sampleNumber and weight. Search the Internet for a brief description of each rock type and assign it to the description field.

Part C

Create an application called DemoRocks that prompts the user for the type of rock collected.

If the user does not enter U$,$ I, S$,$ or M for the rock type, then create a Rock with sample number $0$ and weight $0.$ If the user selects a valid rock type, then prompt the user for the sample number and the weight.

Create the appropriate type of Rock, then pass it to a method that accepts a Rock parameter and displays all the details for the Rock.

An example of the program is shown below:

Enter type of rock:

U for Unclassified, I for Igneous

S for Sedimentary, or M for Metamorphic $>>$ I

Enter sample number $>>223$

Enter weight in grams $>>6\mathrm{.}8$

Sample # $223$ weighs $6\mathrm{.}8$ grams

Description: Igneous rocks are crystalline solids

which form directly from the cooling of magma.

Task $01$: Create the Rock class.

Task $02$: The Rock class contains the correct data fields.

Task $03$: The Rock class contains a blank, default constructor and an overloaded constructor.

Task $04$: The Rock class contains get methods for each data field.

Task $05$: Create the IgneousRock class with an overloaded constructor.

Task $06$: Create the SedimentaryRock class with an overloaded constructor.

Task $07$: Create the MetamorphicRock class with an overloaded constructor.

Task $08$: Create the DemoRocks class.

Task #$09$: $[$CDEV$-10048]$ Task $9$: The DemoRocks program accepts user input and displays details about the rocks.
