Include a constructor that accepts parameters for the sample number and "weight. The Rock constructor sets the description value to Unclassified. Include get methods for each field. Create three child classes named IgneousRock, SedimentaryRock, and MetamorphicRock. The constructors for these classes require parameters for the sample number and weight. Search the Internet for a brief description of each rock type and assign it to the description field.
