Create a java application• shape is an abstract class including two private instance variables: height and width, a constructor, set and get methods (height and width must be greater than 0, otherwise throw illegalargumentexception), tostring method, and an abstract method called getarea.• the class rectangle has one private instance variable: color, a constructor, set and get, tostring, and getarea methods.• the class triangle has one private instance variable: classification (for example; equilateral), a constructor, set and get, tostring, and getarea methods.• create a test file named shapetest. create one object from the classes rectangle and triangle. then, create an array of shape references to objects of each subclass in the hierarchy.• then, create an enhanced for loop that processes all the shapes in the array. if the object belongs to class triangle, display a message that the object is a triangle. if the object belongs to class rectangle, display a message that the object is a rectangle.

You have a linux system that has a 1000gb hard disk drive, which has a 90gb partition containing an ext4 filesystem mounted to the / directory and a 4gb swap partition. currently, this linux system is only used by a few users for storing small files; however, the department manager wants to upgrade this system and use it to run a database application that will be used by 100 users. the database application and the associated data will take up over 200gb of hard disk space. in addition, these 100 users will store their personal files on the hard disk of the system. each user must have a maximum of 5gb of storage space. the department manager has made it very clear that this system must not exhibit any downtime as a result of hard disk errors. how much hard disk space will you require, and what partitions would you need to ensure that the system will perform as needed? where would these partitions be mounted? what quotas would you implement? what commands would you need to run and what entries to /etc/fstab would you need to create? justify your answers.
