(Use the GregorianCa1endar class) Java API has the GregorianCalendar class in the java.util package, which you can use to obtain the year, month, and day of a date. The no-arg constructor constructs an instance for the current date, and the methods get (GregorianCalendar.YEAR), get (GregorianCalendar.MONTH), and get (GregorianCalendar.DAY_OF_MONTH) return the year, month, and day. Write a
- 1. Display the current year, month, and day.
- 2. The GregorianCalendar class has the setTimeinMillis(long) , which can be used to set a specified elapsed time since January 1, 1970. Set the value to 1234567898765L and display the year, month, and day.

Python:Please read the following.
The Game class
The Game class brings together an instance of the GameBoard class, a list of Player objects who are playing the game, and an integer variable “n” indicating how many tokens must be aligned to win (as in the name “Connect N”).
The game class has a constructor and two additional methods. The most complicated of these, play, is provided for you and should not be modified. However, you must implement the constructor and the add_player method.
__init__(self,n,height,width)
The Game constructor needs to initialize three instance variables. The first, self.n, simply holds the integer value “n” provided as a parameter. The second, self.board, should be a new instance of the GameBoard class (described below), built using the provided height and width as dimensions. The third, self.players, should be an initially empty list.
add_player(self,name,symbol)
The add_player method is provided a name string and a symbol string. These two values should be…
Rules:
Corner cases. By convention, the row and column indices are integers between 0 and n − 1, where (0, 0) is the upper-left site.
Throw an IllegalArgumentException if any argument to open(), isOpen(), or isFull() is outside its prescribed range.
Throw an IllegalArgumentException in the constructor if n ≤ 0.
Unit testing. Your main() method must call each public constructor and method directly and help verify that they work as prescribed (e.g., by printing results to standard output).
Performance requirements. The constructor must take Θ(n^2) time; all instance methods must take Θ(1)Θ(1) time plus Θ(1)Θ(1) calls to union() and find().
Method Overloading is a feature that allows a class to have two or more methods having
same name, if their argument lists are different. Argument lists could differ in:
1. Number of parameters.
2. Data type of parameters.
3. Sequence of Data type of parameters.
Write different version of method sum() that display the sum of the values received as
parameter according to the following main method content:
public static void main(String[] args)
{
sum ( 10, 10 );
sum ( 10, 10, 10 );
sum ( 10.0, 10.0 );
sum ( 10, 10.0 );
sum ( 10.0, 10);
}
You have to define five functions with the specified types. Then, demonstrate the Argument
Promotion concept by reducing the number of method to two.

Create a "Car" class that keeps car ids and prices. And create a "Galleries" class that holds the car list for a particular gallery. In this class there should be methods for get / set and print for car name, car number and car list. Adding / Removing Cars to the List in This Class should have methods. And create another method to find and print the IDs of Cars with Car Segment equal to X. (print_id(X)). Car Prices are as follows according to the segments. 0$-19999$ -> Z20000$-29999$ -> Y30000$-44999$ -> T45000$-100000$ -> P Apply the Car list using "Singly Linked List"(Node, newNode, head).arrow_forwardWrite a method for the farmer class that allows a farmer object to pet all cows on the farm.

- Basic Java Help Each year, the Social Security Administration provides a list of baby names for boy and girls by state. You will write a program to read a file containing a list of baby names and display the top names. To start, implement the following class: baby names util = printTopNames(File, int): void printTopNames Will be a static method. It will accept two parameters, one is a File containing the list of names. The other is an integer that indicates how many names to display (ie, top 10 names, or top 50 names, etc). The integer argument could be any valid integer. You do not have to worry about an integer value large than 5 for the boy/girl names. This method should open the file and parse the file and print the names as shown below: Your program will use the Scanner class to read the data from the file (see your text for examples). You will also need to use a delimiter with the scanner so that the scanner will break the line apart based on the commas.

- java program Add a divide method to the following program to take another Fraction as the parameter and return a new Fraction that is the division of current Fraction and the Fraction in the parameter. (public Fraction divide(Fraction f)). - Add scaleup and scaledown methods to the Fraction class. The scaleup method will take a factor as the parameter and multiply the numerator by the factor. The scaledown method will take a factor as the parameter and multiply the denominator by the factor. - Add a scale method that will have two parameters: factor and flag. The flag is boolean. If flag is true, then scale up the fraction; otherwise scale down the fraction. - Both scaledown and scale methods must check if the factor is 0. If it is 0, a warning message is printed out and no scaling is operated. - Add two more constructors. One of the constructors will have no parameters; it initializes the fraction to 0/1. The other constructor will have one parameter, representing the numerator of the…arrow_forwardI already have the code for the assignment below, but the code has an error in the driver class.
