Lab 3 Directions (linked lists) Program #1 1. Show PolynomialADT interface 2. Create the PolyNodeClass with the following methods: default constructor, overloaded constructor, copy constructor, set Coefficient, setExponent, setNext, getCoefficient, getExponent, getNext 3. Create the Polynomial DataStrucClass with the following methods: default constructor, overloaded constructor, copy constructor, isEmpty, setFirstNode, get FirstNode, addPolyNodeFirst (PolyNode is created and set to beginning of polynomial), addPolyNodeLast, addPolyNode (PolyNode is set to the end of polynomial), addPolynomials, toString 4. Create the Polynomial DemoClass: instantiate and initialize Polynomial Data StrucClass objects p1, p2, p3, p4 - - Add terms to the polynomials (pass 2 arguments to the method: coefficient and exponent-for example: p1.addPolyNodeLast(4, 3);) Print out p1, p2 and sum of the polynomials AND p3, p4, and sum of the polynomials Use: p1= 4x^3 + 3x^2 - 5 : p2 = 3x^5 + 4x^4 + x^3 - 4x^2 + 4x^1 + 2 AND p3= -5x^0 + 3x^2 + 4x^3; p4 = -4x^0 + 4x^3 + 5x^4

Write a java program to print the flag of America. Don't hard code it.

Write the necessary Java statements (not necessarily programs) to achieve the indicated task. To display the string CUNY 50 times on the screen on separate lines. Need to use a loop.

Given is a Python program that connects to a sqlite database and has one table called writers with two columnns: name - the name of a writer num - the number of works the writer has written The writers table originally has the following data: name, num Jane Austen,6 Charles Dickens,20 Ernest Hemingway,9 Jack Kerouac,22 F. Scott Fitzgerald,8 Mary Shelley,7 Charlotte Bronte,5 Mark Twain,11 Agatha Christie,73 Ian Flemming,14 J.K. Rowling,14 Stephen King,54 Oscar Wilde,1   Update the Python program to ask the user if they want to update entries or add new entries. If the name entered already exists in the writers table then the database record is updated, overwriting the original contents. If the name does not exist in the writers table, then add a new record with the writer's name and number of works. The following TODO sections must be completed. Check if a writer exists in the writers table If the writer exists in the table, locate an entry to be updated by writer's name and update…

In a Java application, we know that we must have a Main method to run the program.  What tells the Main method to run and what would happen if you did not include the Main method in your Java application?
