Program Plan Intro

Boolean expression:

  • A Boolean expression is an expression that contains a sequence of identifiers separated using the operators that evaluates to Boolean variable, which means either true or false.
  • The Boolean expression is as follows:
  • Boolean variable
    • A Boolean variable is a variable or a data type which is placed in memory and referenced by an identifier.
    • Boolean variable contains two values “true” or “false”.
  • Relational operator
    • Relational operators are used to compare numeric and character values.
    • It has six relation operators which will compare two numbers and returns a Boolean value.
      • < (Less than)
      • > (Greater than)
      • <= (Less than or equal to)
      • >= (Greater than or equal to)
      • ! = or <> or /= (Not equal to)
      • = or == (equal)
        • The result of the comparison will be either “true” or “false”.
        • The Boolean value is hold by the variable called Boolean variable.
        • The data type “Boolean” is used to declare the Boolean data type.
  • Boolean operator
    • The Boolean operator is a special operator and subset of the Boolean algebra that produces the “true” or “false” statement.
    • The “AND”, “OR”, and “NOT” are the Boolean operators.

Suppose you buy an electronic device that you operate continuously. The device costs you $300 and carries a one-year warranty. The warranty states that if the device fails during its first year of use, you get a new device for no cost, and this new device carries exactly the same warranty. However, if it fails after the first year of use, the warranty is of no value. You plan to use this device for the next six years. Therefore, any time the device fails outside its warranty period, you will pay $300 for another device of the same kind. (We assume the price does not increase during the six-year period.) The time until failure for a device is gamma distributed with parameters α = 2 and β = 0.5. (This implies a mean of one year.) Use @RISK to simulate the six-year period. Include as outputs (1) your total cost, (2) the number of failures during the warranty period, and (3) the number of devices you own during the six-year period. Your expected total cost to the nearest $100 is _________,…
Which one of the 4 Entities mention in the diagram can have a recursive relationship?    If a new entity Order_Details is introduced, will it be a strong entity or weak entity? If it is a weak entity, then mention its type (ID or Non-ID, also Justify why)?
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…
