2- Consider the following program:public class Product{ private int price;public void setPrice(int theprice){price = thePrice;}}public class SpecialProduct extends Item{ private int discount;public void setDiscount(int theDiscount){discount = theDiscount;}}public class Main{public static void main(String[]args){SpecialProduct product = new SpecialProduct();}}Which of the following compiles without a problem? Why?a. product.discount = 20;b. product.setDiscount(20);c. product.setPrice(50);

Object-oriented programmingcreate a program that manages the production of a company. The production of each of the months of the year 2021 is saved, the average production of the year is also stored.Include a method to display all company information.Include at least three public or private type attributes. If they are private don't forget to include the getter and setter methods ONLY for private attributes.Include both default and parameterized constructors.Your program must allowShow all company dataRequest company dataShow the name of the month that had the highest production.Show the name of all the months with production less than the annual average.Identify the methods that are of the class and those that are of the main program.DO NOT forget that attributes, methods, classes, objects and messages are written in English.The MIN and MAX methods must be part of the main program. NOT of the class
1) Through BlueJ, the class must define a method called isSpace that allows the book club staff to determine whether there is enough capacity for a group to attend. This method must take a single integer parameter representing the size of the group, and return a boolean result. The method must work as follows: If the value of the parameter is less-than or equal-to 0 then the method must return false. This case has priority over those following. If the value of the parameter is less-than or equal-to the space left in the book club (use the capacity and occupancy values in the to work this out) then the method must return true. Otherwise (i.e., if there is not space in the book club for the whole group) then the method must return false. 2) This method must not change the state of the BookClub object. In other words, both the current number of occupants and the capacity of the club must be exactly the same after it is called as it was before (Note that the return type of this method…
Hr, Min, Sec Constructors to handle: default, (4, 15, 6), (1,30), (14), (clock1) Overload <> ++,, >=, ==, != Get and Set methods. Write a tester program that creates 2 clocks(Input from the user). The first clock will represent the real time and one will represent your alarm clock. Do a loop that will continue to add 1 second to the current time and stop when it reaches the alarm clock time. Display the time each second on the screen. You can use system("CLS"); to clear the screen each time so it looks like it is overwriting the current time. #include void main() { system("cls"); }

IN JAVA Cartesian Item Programming Depiction of the test: The Cartesian result of two arrangements of numbers An and B is characterized as the arrangement, all things considered (a,b) where an is an individual from An and b is an individual from B. It is frequently addressed by the image A x B and is alluded to as the Cartesian item since it starts in Descartes' meaning of logical calculation. The Cartesian result of two arrangements of genuine numbers is as requested sets. for example An equivalents [1, 2, 3]. B approaches [4, 5]. C = [(1, 4), (1, 5), (2,4), (2.5), (3,4), (3,5)] is the Cartesian item. Presently, given a facilitate tuple (i,j), where I signifies A[i] and j indicates B[j], and knowing A, B, develop a capacity that profits the file of a part in Cartesian item C as per (i,j) Introduction code: Primary public class /** * Repeat over the information lines individually. */ IOException is tossed by open static void main(String[] args). new…
How can I express the following situation in Java programming? Orcs, Hobbits, and Tom Bombadil We have n-1 Orcs and n Hobbits who want to cross a river. We also have Tom Bombadil who wants to cross as well. Only Hobbits and Tom Bombadil can row the boat (don’t ask　me why!) At all times, the number of Hobbits on either side of the river must be greater or equal the number of Orcs on that side (unless there are no Hobbits on that side), or the Hobbits will be killed by the Orcs! If the boat holds 2, with n=4 or more, the problem has no solution. If the boat can hold 3, then up to n=5 can be solved. If the boat can hold 4, any number (n) Hobbits can cross. So -- if n = 1,2 or 3 - use a boat of size 2. If n = 4 or 5 - use a boat of size 3. If n > 5 use a boat of size 4. If n <0 invalid input if n = 0 no output.

TressetteYou are given the types: type colore = Spade | Coppa | Bastoni | Denari ;; type valore = Ace | Two | Three | Four | Five | Six |Seven | Jack | Knight | King ;; type mazzo = Null | Carta of carta and carta ={ c : colore ; v: valore ; mutable tl : mazzo };; (see the picture with cards) a. Write a function points : mazzo -> int = that given a deck of cards calculates its point score. The scoring is as follows: Ace is worth 1 point; Two, Three, King, Knight, Jack are each worth 1 3 ; and the rest do not contribute the the point total. The total point score is equal to the sum of the individual points, rounded down at the end. b. Write a function max_cards : mazzo -> mazzo = that takes a deck of cards and filters out everything except the greatest cards by value (valore) of each color. The order of cards by value is as follows: Three > Two > Ace > King > Knight > Jack > Seven > Six > Five > Four. Due to the size of the output, lists like…
