Chapter 9, Problem 11PP

Write an application that implements a trip-time calculator. Define and use a class TripComputer to compute the time of a trip. TripComputer should have the private attributes

  • totalTime—the total time for the trip
  • restStopTaken—a boolean flag that indicates whether a rest stop has been taken at the end of the current leg

and the following methods:

  • computeLegTime (distance, speed) —computes the time for a leg of the trip having a given distance in miles and speed in miles per hour. If either the distance or the speed is negative, throws an exception.
  • takeRestStop (time)—takes a rest stop for the given amount of time. If the time is negative, throws an exception. Also throws an exception if the client code attempts to take two rest stops in a row.
  • getTripTime—returns the current total time for the trip.
  • Here is one possible configuration of the labels, buttons, and text fields required by the trip-time calculator:

Computer Science You are required to develop a small chatting application where two or more friends can communicate each other through messages. Create a class Message which has Date d, and message (string). Provide getters/setters, constructors, toString. Create a class Friend having String name, String contact, email and ArrayList of Messages provide getters/setters, constructors, toString addMessage(Message m) method which will add new message to the list. Provide following options to the user using JFrame. Login which will help user login to the application. View Friends (Display List of All Friends) View Messages ( This should display all message of a Friend) Send message (This should ask for friend name and message match the friend name and write that message to the array list).
Shape Class JAVA Implement the Shapehierarchy shown in figure below. Shape TwoDimensionalShape ThreeDimensionalShape Circle Square Sphere Cube Each TwoDimensionalShape should contain method getArea to calculate thearea of the two-dimensional shape. • Each ThreeDimensionalShape should have methods getArea and getVolume tocalculate the surface area and volume, respectively, of the three- dimensional shape. Add OneDimensionalShape with sub classes , and add more shapes to classes (TwoDimensionalShape , ThreeDimensionalShape ). Create a program that uses an array of Shape references to objects of each concrete class in the hierarchy. The program should print a text description of the object to which each array element refers. • Also, in the loop that processes all the shapes in the array, determine OneDimensionalShape, whether each shape is a TwoDimensionalShape or a ThreeDimensionalShape. If it is a TwoDimensionalShape, it is display ThreeDimensionalShape, display its area and volume. its…
Exercise 6 - Loaded Coin Simulation Make a new class in the Lab2 project called LoadedCoinSim that simulates the toss of a loaded coin. A coin is loaded when it is constructed such that it is more likely to land on one value than another. Assume the probability the coin will land head is HEAD_PROB, and declare that as a constant in your program. Initially, use a value of 0.75, which means 75% chance the coin will show heads. Given this probability, simulate ten coin tosses and displaying the result. At the end, display the number of times the coin showed heads. The output should appear like this: Toss 1: HEADS Toss 2: HEADS Toss 3: HEADS Toss 4: TAILS Toss 5: HEADS Toss 6: HEADS Toss 7: HEADS Toss 8: HEADS Toss 9: TAILS Toss 10: HEADS Number of heads = 8
