in java

Create a command line program that can be used for computer inventory purposes

• Create a super class that will store the following data:
  • CPU speed
  • Amount of RAM
  • Hard Disk size
  • Operating System
• Allow the user to enter data using any units of measurement they desire (i.e. - 500GB or 1TB for hard disk size).
• Create a class that inherits from the previous class and stores information for a Windows based computer. Store the following additional information:
  • Manufacturer
• Create a class that inherits from the first class and stores information for a Mac based computer. Store the following additional information:
  • Type of Mac (iMac, Mac Mini, etc.)
• Create display methods in the Windows and Mac classes to display all information including info from the super class.
• Make all variables in the previous three classes private or protected as appropriate.
• Create accessor and mutator methods for all variables in the previous classes.
• Create a demo program:
  • Create one object from the Windows class. Call each mutator method and assign a value to it (do not ask for user input).
  • Create one object from the Mac class. Call each mutator method and assign a value to it (do not ask for user input).
  • Display the values for both the Windows and Mac objects.
