47. What statement of the following is the most appropriate? Group of answer choices The node class defined in the textbook can be implemented as a template class, providing more limitation to implement other container classes. The node class defined in the textbook can be implemented as a template class, providing more memory leak possibility to implement other container classes. The node class defined in the textbook can be implemented as a template class, providing more flexibility to implement other container classes. The node class defined in the textbook can be implemented as a template class, providing more tool box to implement other container classes. The node class defined in the textbook can not be implemented as a template class.
1, Show the LinkedtStackADT<T> interface 2. Create a LinkedStackDS<T> with the following methods: default constructor,overloaded constructor, copy constructor, isEmptyStack, push, peek, pop 3. Create a private inner StackNode<T> class with the following methods: defaultconstructor, overloaded constructor, toString 3. Exception classes: StackException, StackUnderflowException,StackOverflowException 4. Create a PalindromeDemo class that instantiates a LinkedStackDS<Character>object. Execute a do-while loop that asks the user using dialog boxes to “Input aString for Palindrome Test:” Use the replaceAll method to remove all blanks andspecial characters from testStr. Output whether or not it is a palindrome in adialog box. [Use the 5 inputs given on the other handout sheet for testing.]
Compliant/Noncompliant Solutions The following code segment was provided in Secure Coding Guidelines for Java SE: void readData() throws IOException{ BufferedReader br = new BufferedReader(new InputStreamReader( new FileInputStream("file"))); // Read from the file String data = br.readLine();} The code is presented as a noncompliant coding example. For this assignment, identify two compliant solutions that can be utilized to ensure the protection of sensitive data. Provide a detailed explanation of factors, which influence noncompliant code and specifically how your solutions are now compliant. Your explanation should be 2-3 pages in length. Submit the following components: Word document with appropriate program analysis for your compliant solutions and source code in the Word file. Submit your .java source code file(s). If more than 1 file, submit a zip file.
Step 1: Read your files! You should now have 3 files. Read each of these files, in the order listed below. dynamicarray.h contains the class definition for DynamicArray. Be sure you fully understand the changes to the class definition: arr is defined differently ● O -- o A new variable, capacity, has been added o A new member function, cap(), has been added to allow external access to the capacity. This is to make sure you're resizing correctly. dynamicarray.cpp -- contains the definition of the print() function for DynamicArray. main.cpp client code to test your dynamicarray class. o Note that the multi-line comment format (/* ... */) has been used to comment out everything in main below the first print statement. As you proceed through the lab, you will need to move the starting comment (/*) to a different location. Other than that, no changes ever need to be made to this file.
Create a header and source files that contain the class definition and implementation of the following members: a. Define studentName (string), studentId(string), and grade (float) data members. b. Define three constructors to initialize the data members. c. Define member methods to implement the creation, insertion (could be anywhere), and deletion (could be anywhere) of student records implemented as linked list. Name the source file that contains the main function as ProgExer03.cpp. You may choose an appropriate name for the class header and source files.
First, create the custom exception class called OutOfStockException by creating a new class that extends the Exception class The class has a single constructor that takes a single argument, a string called message. The message argument is passed to the parent class (Exception) via the super keyword. Create the Store class and import the java.util.HashMap and java.util.Map classes The Store class is defined with a private Map called products, which is used to store the product names and their corresponding quantities. Create a default constructor that initializes the products map with three items: "apple", "banana", and "orange", with respective quantities of 10, 5, and 0. Define thepurchase method , which takes two arguments: a product name and a quantity to be purchased. This method throws an OutOfStockException if either the specified product is not available in the store or if the requested quantity is greater than the quantity available in stock. The method first…

2. Team Class a. Variables i. Trainer -> String Gym - >String Members ->arrayList of type pokemon iv. ii. ii. saveFile ->a constant string that is the filename of "teamData.record" b. Methods i. Accessor and Mutator methods for all variables ii. setTeam - >sets all variables for a team ii. 2 Constructors addMember 1. Add a pokemon to the members arraylist 2. readlnput for such pokemon V. saveData 1. Writes all data from this class to the binary file saveFile vi. loadData 1. Loads data from saveFile 2. Set the team using the setTeam method vii. writeOutput 1. Prints all data for a team including printing all data for each pokemon in the members arraylist 2. Before printing pokemon data, ensure that you use Collections.sort(members) on the members arrayList. You can look up how this method works, but it should use the compareTo that we set up in the pokemon class and sort the pokemon into alphabetical order before printing.
