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.
Given the following C code: struct Node int data; struct Node struct Node next; prev; struct Node head; void funx ( ) if (head==NULL) return; struct Node current=head; while (current->next!=NULL) current=current-->next; while (current!=NULL) printf("&d ", current->data; current=current->prev; What is the functionality of this function? a) Print the contents of linked list b) Print the contents of linked list in reverse order c) None
It is python language Write the code that creates a new Node class. It will store data and next attributes. You only need to create the __init__ method. data and next variables will have default values, both set to None. Assume you are using the Node class from the previous connection to create a LinkedList. You have the code below, create a method that removes the first node from the LinkedList. class LinkedList: def __init__(self): self.head = None Based on the code from the last two questions, create a new LinkedList. Add 2 values to the LinkedList (there is an add method that accepts data as an argument, called add). Then call the removeFront method created in the previous question. Based on the previous questions, create a Queue class that uses the LinkedList for its data storage. Create the __init__, isEmpty, insert, remove, and size methods. Assume that LinkedList class has the add, removeFront and size methods defined. Based on the LinkedList code already…

1. Goals and Overview The goal of this assignment is to practice creating a hash table. This assignment also has an alternative, described in Section 5. A hash table stores values into a table (meaning an array) at a position determined by a hash function. 2. Hash Function and Values Every Java object has a method int hashCode() which returns an int suitable for use in a hash table. Most classes use the hashCode method they inherit from object, but classes such as string define their own hashCode method, overriding the one in object. For this assignments, your hash table stores values of type public class HashKeyValue { K key; V value; } 3. Hash Table using Chained Hashing Create a hash table class (called HashTable211.java) satisfying the following interface: public interface HashInterface { void add(K key, V value); // always succeeds as long as there is enough memory V find (K key); // returns null if there is no such key } Internally, your hash table is defined as a private…
