Program Plan Intro

a.

Logic gate:

  • Logic gate is an electronic circuit that is used to perform logic decisions based on the input.
  • It contains one or more number of inputs and one output.
  • The working of logic gate is based on the binary principle that has two states either logic 0 or logic 1.
  • The output of logic gate is produced when it satisfies any of its logic conditions.
  • The logic condition depends upon the type of the gates and the number of inputs.
  • The primary logic gates include AND, OR, and NOT. And the combinations of these gates are used to implement any of the other logic gates.

AND gate:

The two-input AND gate is a logic gate, whose output will be high when all the inputs are high and whose output will be low when any one of the inputs is low.

OR gate:

The OR gate is a logic gate, whose output will be high when any of the inputs are high and whose output will be low when all the inputs are low.

NOT function:

The NOT gate is a logic gate; whose output will be high when the input is low and whose output will be low when the input is high. In other words, NOT gate always complement or invert its output.

NAND gate:

The NAND gate performs the reverse operation of AND gate. The two-input NAND gate is a logic gate, whose output will be high if any of the inputs are low and whose output will be low when all the inputs are high.

NOR gate:

The NOR gate performs the reverse operation of OR gate. The two-input NOR gate is a logic gate, whose output will be high if both the inputs are low and whose output will be low when any one of the inputs is high.

Please answer the JAVA OOP Programming Assignment scenario below: Patriot Ships is a new cruise line company which has a fleet of 10 cruise ships, each with a capacity of 300 passengers. To manage its operations efficiently, the company is looking for a program that can help track its fleet, manage bookings, and calculate revenue for each cruise. Each cruise is tracked by a Cruise Identifier (must be 5 characters long), cruise route (e.g. Miami to Nassau), and ticket price. The program should also track how many tickets have been sold for each cruise. Create an object-oriented solution with a menu that allows a user to select one of the following options: 1. Create Cruise – This option allows a user to create a new cruise by entering all necessary details (Cruise ID, route, ticket price). If the maximum number of cruises has already been created, display an error message. 2. Search Cruise – This option allows to search a cruise by the user provided cruise ID. 3. Remove Cruise – This op…
I need to know about the use and configuration of files and folders, and their attributes in Windows Server 2019.
Southern Airline has 15 daily flights from Miami to New York.  Each flight requires two pilots.  Flights that do not have two pilots are canceled (passengers are transferred to other airlines).  The average profit per flight is $6000.  Because pilots get sick from time to time, the airline is considering a policy of keeping four *reserve pilots on standby to replace sick pilots.  Such pilots would introduce an additional cost of $1800 per reserve pilot (whether they fly or not). The pilots on each flight are distinct and the likelihood of any pilot getting sick is independent of the likelihood of any other pilot getting sick.  Southern believes that the probability of any given pilot getting sick is 0.15.  A) Run a simulation of this situation with at least 1000 iterations and report the following for the present policy (no reserve pilots) and the proposed policy (four reserve pilots): The average daily utilization of the aircraft (percentage of total flights that fly) The…
