Assume the existence of a Window class with the following methods: - widen - accepts no arguments; doubles the width of the window - setHeight - accepts an integer argument corresponding to the new height of the Window - getWidth and getHeight - accept no arguments, return the width and height of the window respectively. There is also a subclass, TitledWindow whose constructor accepts a width and height (bot integers), and a title (a string) -- in that order. TitledWindow also has a method, setText that accepts a string, allowing the title of the window to be changed. Declare a variable, tWindow, of type TitledWindow variable, and initialize it to a window with a width of 50 and a height of 75, and a title of "Rectangular Window". Double the width of the window, using widen, set the height of the window so that it is the same as the width, and set the title to the new value "Square Window".

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.
