Array/Array List Operations Write a menu-driven JAVA program that performs the following array/vector operations: a) Reverse the sequence of elements in an array/array list. For instance, if the array/array list contains , after choosing this option, the array/array list will contain . b) Append one array/array list to another. For instance, if a is and b is , after choosing this option the following will be returned: c) Merge two array/array list, alternating elements from both. If one is shorter than the other, append the remaining elements from the longer array/array list. For instance, if a is and b is , after choosing this option, the following will be returned: . d) Remove duplicates from an aray/array list. For instance, if the array/array list contains , after choosing this option, the array/array list will contain . Your Main should display a menu with the following options: - Enter first array/array list - Enter second array/array list - Reverse array/array list - Append array/array list - Merge array/array list - Remove duplicate from array/array list - Quit You should also perform appropriate error checking and output messages to the user as needed. In this unit, we explore a different concept of urban planning, created by Ebenezer Howard. His idea of the Garden City was considered to be revolutionary after what people had witnessed cities become during the Industrial Revolution. In previous units, we have explored many different designs. For example, in Unit 3, we read about Haussmann’s restructuring of Paris, which looked very similar to what we see today in Gentrification of Urban settings. Unlike Haussmann, the elements of Howard's plan were meant to reform the way of life in heavily populated urban areas. With the goal of creating a sustainable environment and community for all, Howard proposed a way of life that combined both urban and suburban styles of living. Howard describes his alternative approach in three scenarios which he referred to as, “The Three Magnets,” The Town, The country, and The Town-Country Magnet. The Town-Country magnet allowed for a person to get the best of both worlds, and developed into what he named The Garden City. The city would be built across 6,000 acres complete with a sustainable and well-watered garden in the center. Once the population reached 3,000 people…a new town was formed. Each town was to be unique, but was also to be connected back to the same large plan. There were also plans for these towns to be more than just a means of shelter, but social cities. The land was not in the hands of private owners but in the hands of the people, to be administered in a way that they felt would best benefit the community. He aimed to have his towns and their people surrounded by the most “healthy and advantageous conditions” possible, and each generation would ensure that their society met their needs. Many called Howard’s plan utopian, and felt it would never work. However, other Garden cities emerged around the same time emulating the same goals and beliefs as the Garden City. “Garden Cities of Tomorrow” For this week’s discussion: 1. What do you think are the most successful aspects of the Garden City? 2. What elements of the Garden City are similar to Haussmann’s plan? 3. Identify a city that was influenced the most by the Garden City and in what ways.

The implementation of algorithmic concepts through practical programming tasks enhances understanding of both data structures and real-world problem solving. In this paper, we explore the development of a comprehensive, menu-driven Java application designed to perform essential array and ArrayList operations. Such operations include reversing data sequences, appending and merging lists, and removing duplicates, which are fundamental in various computational and data management tasks.
To begin, the architecture of the program revolves around providing an interactive menu to the user, enabling seamless selection and execution of desired operations. The core functionalities are structured to ensure robustness, including appropriate error-checking mechanisms to handle exceptions such as invalid inputs or empty lists. The program utilizes Java's ArrayList class for dynamic data management, owing to its flexibility and built-in methods that facilitate operations like appending, merging, and removing duplicates.
The first feature implemented is reversal of the list. Reversing an array or list is a simple yet essential operation, especially for data processing tasks. This is achieved by iterating through the list from the end to the beginning and reordering elements accordingly. The method ensures that the original sequence is inverted, providing a new view of the data that can be useful in various contexts such as undo operations or data analysis.
Next, the program allows appending one list to another. This entails combining two lists into a single list while maintaining the order of elements. The implementation involves using the addAll() method of ArrayList, which appends all elements of one list to the end of another seamlessly. Error handling is critical here to verify that the lists are properly initialized before performing the operation.
The merging of two lists in an alternating fashion follows, where elements from both lists are interleaved. This operation continues until all elements from the shorter list are exhausted, after which the remaining elements of the longer list are appended. This functionality is particularly useful in scenarios requiring interleaving datasets or creating composite sequences in multimedia applications.
Removing duplicates from a list is another vital feature that simplifies data sets by eliminating redundancy. This can be accomplished by constructing a LinkedHashSet from the list, which preserves insertion order while removing duplicates. The list is then reconstructed from the set, ensuring the final dataset contains unique elements only, a common requirement in data cleansing.
The program design emphasizes user interaction, requiring initial input of data for two separate lists, followed by options to manipulate these lists according to user selection. Error messages guide users through incorrect inputs or actions that cannot be performed, ensuring a user-friendly experience. Furthermore, the menu repeats until the user chooses to quit, allowing multiple operations in a single session.
In conclusion, the development of this Java program demonstrates essential programming skills such as handling collections, user input validation, and implementing common algorithms. The operation of reversing, appending, merging, and deduplicating lists collectively forms a fundamental toolkit that can be applied in numerous applications, from data analysis to software development. Proper error handling and a clear user interface enhance the usability and robustness of the system.
