What is missing link describe briefly with an example class 11?

allsm [11]

A missing link is a long-extinct organism that filled in a gap between closely related species that now coexist on Earth, such as between apes and humans or reptiles and birds.

A possible or recent transitional fossil is referred to as the "missing link." In the media and in popular science, it is widely used to describe any novel transitional form. Initially, the expression was used to describe a hypothetical transitional form that existed between anthropoid ancestors and anatomically modern humans. The term was influenced by both the pre-Darwinian evolutionary theory known as the Great Chain of Being and the now discredited notion that simple species are more primitive than sophisticated ones. Human evolutionary phylogenetic tree. Since evolutionary trees only hold information at their tips and nodes, and the rest is relied on conjecture rather than fossil evidence, geneticists have supported the idea of the "missing link." But anthropologists no longer like it because of what it suggests.

In this assignment, you will design and create an ArrayList-based application that manages a collection of DVDs. Information abo

sergij07 [2.7K]

Create and design an arraylist based application which manages a DVDs collection.

Explanation:

DVD movie consists of a title, a rating (e.g. PG, R, etc.), and a running time in minutes.

In this project, you will create an application to allow the user to maintain a collection of DVD movies using an array.

When the application starts up, it will read in the DVD data from a text file to initialize the array, if the file is available. If the file is not there, then the program starts with an empty array. If the file is corrupted (has an invalid or missing value), then the program stops its initialization at the point of the error. The data file should contain one DVD per line, with title followed by rating followed by running time in minutes, all separated by commas. You may assume titles are all in uppercase and do not contain commas. For example:

ANGELS AND DEMONS,PG-13,138

STAR TREK,R,127

UP,PG,96

The titles may not be in alphabetical order, but the DVDs should be inserted into the array in alphabetical order.

The application will then allow its user to perform the following operations:

ADD OR MODIFY DVD - The user will be prompted to enter the title, rating and running time (in minutes) for a DVD. If the title is already in the array, then the rating and running time are updated to the supplied values. If the title is not in the array, a DVD is added to the array so that the array is sorted by title. Convert all titles to uppercase only.

REMOVE DVD - The user will be prompted to enter the title of a DVD. If the title is in the array, then the DVD is removed, shifting subsequent DVDs over one position to fill in the gap left by the removed DVD. Again, titles must match exactly (in uppercase).

GET DVDs BY RATING - The user will be prompted to enter a movie rating (e.g. PG). This operation displays a string containing all DVDs matching the given rating in the order that they appear in the DVD collection, separated by newline characters.

GET TOTAL RUNNING TIME - This operation displays the total running time of all DVDs in the collection for the user.

SAVE & EXIT - The user can quit the program, performing an automatic save if the DVD collection has been modified.

Java Files

DVD.java - A class to model a single DVD, including its title, rating and total running time.

DVDCollection.java - A class to model a collection of DVDs using an array.

DVDUserInterface.java - An interface that describes the operation required for any user interface to this DVD collection.

DVDGUI.java - A class that implements the DVDUserInterface interface and provides a graphical user interface to the DVD collection.

DVDConsoleUI.java - A class that implements the DVDUserInterface interface and provides a console user interface to the DVD collection.

DVDManager.java - A class that contains a main method that launches one of the two user interfaces for the user to work with the DVD collection based on the user input.

Complete the DVD class by completing the given methods (constructor, accessors and mutators). Add javadoc comments so you can generate a javadoc documentation file showing how to use this class.

The DVDCollection class uses an array to maintain the collection of DVDs. The DVDs should be stored in alphabetical order based on title starting at position 0 in the array, using adjacent cells. All titles should be stored in uppercase only and are assumed to be unique (no duplicates).

toString - returns a string containing all of the DVDs in the collection, separated by newlines characters, along with the value of numdvds and the length of the DVD array for debugging purposes. The string should be formatted as shown in the example below:

numdvds = 3

dvdArray.length = 7

dvdArray[0] = ANGELS AND DEMONS/PG-13/138min

dvdArray[1] = STAR TREK/R/127min

dvdArray[2] = UP/PG/96min

addOrModifyDVD - given the title, rating and running time of a DVD, add this DVD to the collection if the title is not present in the DVD collection or modify the DVD's rating and running time if the title is present in the collection.insert the DVD so that all DVDs are in alphabetical order by title.

removeDVD - given the title, this method should remove the DVD with this title from the collection if present. The title must match exactly (in uppercase). If no title matches, do not change the collection.

getDVDsByRating - given the rating, this method should return a string containing all DVDs that match the given rating in the order that they appear in the collection, separated by newlines.

getTotalRunningTime - this method should return the total running time of all DVDs in the collection. If there are no DVDs in the collection, return 0.

loadData - given a file name, this method should try to open this file and read the DVD data contained inside to create an initial alphabetized DVD collection.

save - save the DVDs currently in the array into the same file specified during the load operation, overwriting whatever data was originally there.
