Chapter 11, Problem 2E

Write a method that takes two string parameters, and tells whether the first is a substring of the second. You can't use framework methods that do this for you, such as indexOf(). In other words, you have to write the loops yourself. But, you can use the primitive methods such as charAt(). Also analyze the program's performance and state the big-O complexity of your method. Provide a screenshot of the code working.

Write a mock Armor class. You will only need the protect() method. Paste it into the space below.

Write a Rectangle class to represent rectangles, with two data fields (width, height) and four methods (input data, display data, calculate and return area, calculate and return perimeter). Write another class to test all methods of the Rectangle class.

Write a new snowflake class that extends AbstractShape. Your snowflake should be a unique and simple shape unlike any other student’s. Use the drawing methods provided in the imported Graphics class The SimpleSnowFlake is provided in the project as an additional reference.  Add an equals(Object o) method that will compare unique instance variable data and return true if two of your snowflakes are the same. Your equals method should override the method from the Object class and call the equals method of AbstractShape Your snowflake should be a different color and move in a different and unique way.

also need help Write a second constructor that takes a String array of pages as input and sets the String array instance variable equal to the input. Continue to default the page number to zero. Part 2: Write a getter and a setter method for the current page number variable. The setter should check to make sure that the input is a valid page number and only update the variable if the new value is valid. Part 3: Write a getCurrentPage method that returns the String of the current page indexed by current_page.     public class Ebook{    private String[] pages;    private int current_page;    //constructor    public Ebook()    {        this.pages = {"See Spot.", "See Spot run.", "Run, Spot, run."};        this.current_page = 0;    }}

Add a new Java class to your project by right clicking on the src folder in the Project pane and select New > Java Class.Enter Hours as the name for this class, and IntelliJ will add it to the files in the src folder for your project. Remember tocopy and insert the standard heading for the main method as you did for Program 2.Write a program that prompts the user to enter a number of hours, and produces the equivalent number of days as a wholenumber along with the number of hours left over. Assume that a day has exactly 24 hours. The following example showsthe format to use for your output, where the input entered by the user is underlined.Enter the number of hours: 100100 hours is 4 days, plus 4 hours.Define Variables: The number of hours will be a whole number, and we would like to obtain results as whole numbers ofdays and hours, so use the int data type to declare the variables to hold the numbers of hours input, as well as the results(the number of days and number of hours left…

Complete the following code. Attach the simulation too.

Use the debugger to investigate the clock-display project. Set breakpoints in the ClockDisplay constructor and each of the methods, and then singlestep through them. Does it behave as you expected? Did this give you new insights? If so, what were they?

Create a new project for this program called TestOldMaid and add a class with a main() method. In the project: Copy your Deck and Card class from the earlier project into it. Create a subclass of Deck called OldMaidDeck. It is special because one of the Queens is missing so it only has 51 cards. Create a constructor method that calls the super class constructor, then removes a queen. Override the toString method so it returns the name of the deck and the number of cards in it. Write the test main() method. Create an OldMaidDeck object and deal all the cards to six players. It is ok if not everyone has an equal number of cards. Use arrays or ArrayLists for the players hands. Show the hands of all 6 players. Refer to the web to find out more about the Old Maid card game: https://bicyclecards.com/how-to-play/old-maid/ Fully document all classes with your name, date and description. And each data member and method is documented. Each block that does something is also documented.
