String class: The “String” class provides a number of methods that examines for a string inside of a string. The term “substring” refers to a string that denotes another string’s part. The “startsWith” method would determine whether calling string of object begins with a specific substring. The method returns “true” if string begins with specified substring, it returns “false” otherwise. The “endsWith” method would determine whether calling string would end with a specified substring. The method returns “true” if string ends with specified substring, it returns “false” otherwise. The “regionMatches” method would determine whether specified regions for two strings match. The first argument of this method can be “true” or “false” that indicates whether a case-insensitive comparison could be performed.

Program Plan Intro

String class:

The “String” class provides a number of methods that examines for a string inside of a string.

The term “substring” refers to a string that denotes another string’s part.

The “startsWith” method would determine whether calling string of object begins with a specific substring.

The method returns “true” if string begins with specified substring, it returns “false” otherwise.

The “endsWith” method would determine whether calling string would end with a specified substring.

The method returns “true” if string ends with specified substring, it returns “false” otherwise.

The “regionMatches” method would determine whether specified regions for two strings match.

The first argument of this method can be “true” or “false” that indicates whether a case-insensitive comparison could be performed.

The code given below represents a saveTransaction() method which is used to save data to a database from the Java program. Given the classes in the image as well as an image of the screen which will call the function, modify the given code so that it loops through the items again, this time as it loops through you are to insert the data into the salesdetails table, note that the SalesNumber from the AUTO-INCREMENT field from above is to be inserted here with each record being placed into the salesdetails table. Finally, as you loop through the items the product table must be update because as products are sold the onhand field in the products table must be updated. When multiple tables are to be updated with related data, you should wrap it into a DMBS transaction. The schema for the database is also depicted. public class PosDAO { private Connection connection; public PosDAO(Connection connection) { this.connection = connection; } public void…

Create the PolynomialDemoClass: instantiate and initialize PolynomialDataStrucClass objects p1, p2, p3, p4 Add terms to the polynomials (pass 2 arguments to the method: coefficient and exponent- for example: 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

It is time for you to demonstrate your skills in a project of your own choice. You must DESIGN,ANALYSE AND CODE any method for the GENERIC MyLinkedList class that will manipulate the linkedlist. You can decide yourself what it should be following the specification below:1. Purpose: The method must make logical sense – it should be of some purpose to somebody.You should describe in the text who will use the method for which purpose.2. Clearly explain the problem. Then clearly explain how your method will solve it.3. Test program: Test the method using a wrapped class like Integer however, you will get extramarks if you can test it with the new classes you created in I_Do1 and I_Do2.
