Dynamic Apex: Write test class for this apex code(Not required the output) You are working on the project in which you have to create the apex code in which your task is to define the objects dynamically by using the method argument which is api name in string and a map of string, string as a key value pair. Class Code: public static void modifySobjectData(String str , Map mapofString) { //Retrive the type of Sobject by using the getGlobalDescribe Schema.SobjectType targetType = Schema.getGlobalDescribe().get(str); //Initalize the Object Sobject newobject = targetType.newSobject(); for(String s :mapofString.keySet(O) { newobject.put(s, mapofString.get(s)); } System.debug('newObject' + newobject); //Perform the DML if(targetType != null) insert newobject; } }
Create a new Java Application project called lab_07 Part 1: 1. Copy the source file Square class you crated in Lab 03 and paste the source file in the default package (you may need to fix any problems related to package declaration). 2. Open Square class using NetBeans editor. 3. Modify the class implementation to throw IllegalArgumentException if the side’s length is negative. You should modify the implementation of the arguments constructor and setSide method to throw the IllegalArgumentException. Use the following constructor header as a start: /** * Construct a Square object with the specified side’s length * @param side the side’s length of a square * @throws IllegalArgumentException if the side’s length is negative */ public Square (double side) throws IllegalArgumentException { // implement it } Part 2: 1. Write a program that prompts the user to read two integers and displays their sum. Your program should prompt the user to enter the number again if the input is…
CODE IN JAVA Please look at the attached image for the information about the format the code should be in The code should be in two different .java files one with getFirstName, getLastName and getZipCode; the other file would be containing the main method Design and implement an application that reads a sequence of up to 25 pairs of names and postal (zip) codes for individuals. Store the data in an object of a class called “NameAndZip”, designed to store a first name (String), last name (String), and a postal code (int). Create a driver class called “NameAndZipList”. Assume that each line of input will contain two strings followed by an integer value. You will then create an object for each line read in and store that object in an array of NameAndZip objects. After the Names and Codes have been entered, print the list in an appropriate format to the screen using the toString method in the NameAndZip class. To test the program enter 3 names and codes.
Exercise 2. Create a Book class where: Each book contains the following information: book title book Author name, barcode (as fong integers), and book topic. o Implement an appropriate constructor(s) and all necessary get/set methods. Test Book class: o Create diffcrent book objects (at least 5 hooks) and store them in a LinkedList sorted by book barcode value Generate a unique random integer value for the barcode. Iterate through the LinkedList and print out the books' details O Create a second LinkedList object containing a copy of the above LinkedList, but in reverse order.
Books can come in various formats, like paper books, audio books, ebooks, etc. Create a generic classBook that has as common attributes the title, the year of publication, and the author. The constructor of thisclass should instantiate all three attributes. Override the toString method of class Book that returns a stringthat contains the values of its attributes. Create a subclass PrintBook that extends Book with attributesPublisher and ISBN. Create another subclass AudioBook which has the book’s size (in MB), its playlength and the playback artist’s name as attributes. Both PrintBook and AudioBook classes override thetoString method inherited from Book. Write a Java application to demonstrate the usage of this hierarchy.
In a triangle, the sum of any two sides isgreater than the other side. The Triangle class must adhere to this rule.Createthe IllegalTriangleExceptionclass, and modify the constructor of the Triangleclass to throw an IllegalTriangleException object if atriangle is created with sides that violate the rule, as follows:/** Construct a triangle with the specified sides */public Triangle(double side1, double side2, double side3)throws IllegalTriangleException {// Implement it}

Language - Java Create a utility class called DuplicateCounter. Create an instance method called count that takes a single parameter called dataFile (representing the path to a text file) and uses a Map of Strings to count how many times each word occurs in dataFile. The counts should be stored in an instance variable called wordCounter. Create an instance method called write that takes a single parameter called outputFile (representing the path to a text file) and writes the contents of wordCounter to the file pointed to by outputFile. The output file should be overwritten if it already exists, and created if it does not exist. Create a separate class called Application that contains a main method which illustrates the use of DuplicateCounter by calling both the remove and write methods. Your input file must be called problem2.txt and your output file must be called unique_word_counts.tx

Implement a PowerSeller class that is derived from the Seller class. Create the powerseller.h andpowerseller.cpp files for this class. This derived class contains additional data members include:o the seller’s own web site address (string),o number of items sold in the current year.Methods included in this derived class are:• A default constructor and a copy constructor• A value constructor that receives all data for a power seller• Appropriate get and set functions for the new data• print() – overrides the parent class print() method. This method should call the Sellerclass print method to display all the information from a Person class and the seller class,and also display the additional power seller data with appropriate messages.• read() – overrides the parent class read() method. This method should call the Seller classread method to read all the information for Person class and seller class, and also read inthe information for the specific data for a Power Seller.
