JAVA and use the code at the bottom 28.7 LAB: Acronyms An acronym is a word formed from the initial letters of words in a set phrase. Define a method named createAcronym that takes a string parameter and returns the acronym of the string parameter. Append a period (.) after each letter in the acronym. If a word begins with a lower case letter, don't include that letter in the acronym. Then write a main program that reads a phrase from input, calls createAcronym() with the input phrase as argument, and outputs the returned acronym. Assume the input has at least one upper case letter. Ex: If the input is: Institute of Electrical and Electronics Engineers the output should be: I.E.E.E. Ex: If the input is: Association for computing MACHINERY the output should be: A.M. Although the letters ACHINERY in MACHINERY are upper case, those letters are omitted for being a part of the word MACHINERY. The program must define and call a method:public static String createAcronym(String…
Implement the above system using inheritance in the best possible way. Keep every object size as small as possible. Implement all methods (setter/getter/constructors and destructors) Note that the region area is 0 while the city is len*width and the country is the sum of their cities. Create array of countries called Arab of 22 countries. Write a function fill that fills the array Arab Write a method that finds the city that has the max area in a country Write a method that sorts the cities in a country from the largest to the smallest area Write a function that returns array of countries of the same area of Arab Write a function that compares between two countries. It returns true if country1 area greater than country2 area. Write a function to move a city from one country to another.
Exercise (Section 30/40): Implement a superclass Appointment and subclasses Onetime, Daily, and Monthly. An appointment has a description (for example, "see the dentist") and a date. Write a method occursOn(int year, int month, int day) that checks whether the appointment occurs on that date. For example, for a monthly appointment, you must check whether the day of the month matches. Then fill an array of Appointment objects with a mixture of appointments. Have the user enter a date and print out all appointments that occur on that date. Give the user the option to add new appointments. The user must specify the type of the appointment, the description, and the date.
