Array

The simplest way to start thinking about an array is as a collection, or a set of elements. In programming, these elements may be constants, variables, functions and pointers.

Question

Take the following list of methods:
Student ()
{
// Creates a student object with all fields blank
Student (String name)
{
// Creates a student object with a set name
}
Student (String name, Array [])
{
}
power (int x)
{
// returns x^2
}
power (int x, int y)
{
// returns x^y
}
greet (String name).
{
// returns "Hello, + name + " !";
}
"1
a) What are your options if you want to find the value of a number squared? Which would you
choose if you wanted the method to say something to the user?
b) What 'Student' would you call if you want to create a student when you don't have any
input?
c) What 'Student' would you call if you had a whole array of data to input into the student
object?
d) Why do you think this is a capability that Java has? What uses can you imagine for it?

Python help please! Thank you! Add the following methods to your Boat Race class: Write a method called add_racer which takes in a Boat object and adds it to the end of the racers list. The function does not return anything. Write a method called print_racers which loops through racers and prints the Boat objects. This function takes in no parameters (other than self) and returns nothing. Write a method called count that returns the number of racers. Write a method called race. The race function calls the move function for all of the racers in the BoatRace. Once all the racers have moved, call the print_racers method to display information about the progress of each boat. Then, check if any of the racer’s current_progress is greater than or equal to the race’s distance. If so, then return a list of all of the racers whose current_progress is greater than or equal to distance. If no racer has finished the race then repeat the calls to move and check until at least one…
True or False? In Java, an array is a primitive type that need not be instantiated.
Define a class called Book. This class should store attributes such as the title, ISBN number, author, edition, publisher, and year of publication. Provide get/set methods in this class to access these attributes. Define a class called Bookshelf, which contains the main method. This class should create a few book objects with distinct names and store them in an ArrayList. This class should then list the names of all books in the ArrayList. Enhance the program by providing a sort function, which will sort the books in ascending order of their year of publication. Create a few more Bookobjects with the same names but with different edition numbers, ISBNs, and years of publication. Add these new Book objects to the ArrayList, and display the book list sorted by book name; for duplicate books of the same name, sort the list by year of publication. (Hint: You will need to define a comparator class that takes two Book objects as parameters of the compareTo This method should do a two-step…
Write java code that recursively calculates the Sum of the array cells. Program requirements: Create an array named MyArr and initialize it as follow: 19 27 81 243 88 1- Write a method named ArrSum that recursively calculates the Sum of the numbers in the Array and returns the Sum of the numbers. Hint: Method with 1 parameter (the Array) that returns 1 value (the Array's Sum). 2- Write a method named Display that displays the Array contents and Sum of the numbers. Hint: Method with 2 parameters (the Array) and Sum with no returns (void) 3- Your program output format must be the same as the following: =>> Array Summation Array: 31 19 27 81 243 88 100 6 10 5 Sum: 610 =>> End of the Program Documentation / Comments 31 100 6 10 5

for the class ArrayAverage write a code that calculates the average of the listed numbers with a double result for the class ArrayAverageTester write a for each loop and print out the result
a). Write a method called createArray which takes two parameters a and b, and returns an array that has all integer from a to b. Example 1: a = 6, b = 2 Array is [6, 5, 4, 3, 2] Example 2: a = 4, b = 8 Array is [4, 5, 6, 7, 8] Example 3: a = 4, b = 4 Array is [4] b). In main method, you should ask the user to input two integers a and b. Then call method createArray and print out the array. class Main {public static int[] createArray(int a, int b) {}public static void main(String[] args) {}}
