Expand the example code to have some simple functionality and then write unit tests that integrate with Guice for their behavior.   import com.google.inject.AbstractModule; public class BillingModule extends AbstractModule {   @Override    protected void configure() {      /*       * This tells Guice that whenever it sees a dependency on a TransactionLog,       * it should satisfy the dependency using a DatabaseTransactionLog.       */     bind(TransactionLog.class).to(DatabaseTransactionLog.class);      /*       * Similarly, this binding tells Guice that when CreditCardProcessor is used in       * a dependency, that should be satisfied with a PaypalCreditCardProcessor.       */     bind(CreditCardProcessor.class).to(PaypalCreditCardProcessor.class);   } }

Modify the simulate() method in the Simulator class to work with the revised interface of ParkingLot and the new peek() method in Queue. In addition, implement the getIncomingQueueSize() method of Simulator using the size() method of Queue. The getIncomingQueueSize() is going to be used in the CapacityOptimizer class (next task) to determine the size of the incoming queue after a simulation run.   CODE TO MODIFY IN JAVA: public class Simulator { /** * Length of car plate numbers */ public static final int PLATE_NUM_LENGTH = 3; /** * Number of seconds in one hour */ public static final int NUM_SECONDS_IN_1H = 3600; /** * Maximum duration a car can be parked in the lot */ public static final int MAX_PARKING_DURATION = 8 * NUM_SECONDS_IN_1H; /** * Total duration of the simulation in (simulated) seconds */ public static final int SIMULATION_DURATION = 24 * NUM_SECONDS_IN_1H; /** * The probability distribution for a car leaving the lot based on the duration * that the car has been parked in…

The Java classes GenericServlet and HttpServlet may be differentiated from one another with the assistance of an example.

The map-reduce framework is quite useful for creating inverted indices on a setof documents. An inverted index stores for each word a list of all documentIDs that it appears in (offsets in the documents are also normally stored, butwe shall ignore them in this question).For example, if the input document IDs and contents are as follows:1: data clean2: data base3: clean basethen the inverted lists woulddata: 1, 2clean: 1, 3base: 2, 3Give pseudocode for map and reduce functions to create inverted indices on agiven set of files (each file is a document).Assume the document IDis availableusing a function context.getDocumentID(), and the map function is invokedonce per line of the document. The output inverted list for each word should bea list of document IDs separated by commas. The document IDs are normallysorted, but for the purpose of this question you do not need to bother to sortthem.

Define the abstract base class LinkedSQD_Base using a linked implementation. Indicate whether each field and method should be public, protected, or private, and explain why. Implement each of the ADTs stack, queue, and deque as a class that extends your base class. Repeat parts a and b, but instead define and use the abstract base class ArraySQD_Base using an array-based implementation. Java program

Create an implementation of each LinkedList, Queue Stack interface provided For each implementation create a tester to verify the implementation of thatdata structure performs as expected Your task is to: Implement the LinkedList interface ( fill out the implementation shell). Put your implementation through its paces by exercising each of the methods in the test harness Create a client ( a class with a main ) ‘StagBusClient’ which builds a bus route by performing the following operations on your linked list: Create (insert) 4 stations List the stations Check if a station is in the list (print result) Check for a station that exists, and one that doesn’t Remove a station List the stations Add a station before another station. List the stations Add a station after another station. Print the stations StagBusClient.java package app;  import linkedList.LinkedList; import linkedList.LinkedListImpl; public class StagBusClient { public static void main(String[] args) { // create…
