Starter Code Class Assignment: Using Locale Object

Question

Startercode Class assignment Using Locale object Startercode Class assignment: Using Locale object This assignment involves completing a Java program that demonstrates formatting numbers, currencies, and dates using different Locale settings. The key tasks include utilizing the Locale class to create specific locale instances, formatting numbers and currencies accordingly, retrieving currency details, and displaying dates in different localized formats. The program aims to highlight how localization affects data presentation in Java applications, especially for internationalization purposes. The starter code contains placeholder question marks (?) in critical sections requiring implementation. To complete the assignment, students are expected to substitute these question marks with appropriate code snippets that instantiate Locale objects, specify locale parameters, and access currency information, along with adding relevant comments describing each step.

Localization plays a vital role in creating Java applications that can be used internationally by adapting the presentation of data—such as numbers, currencies, and dates—to conform with local conventions. The Java Locale class provides a means to specify geographical and cultural settings. Proper utilization of Locale objects allows programs to present data in formats familiar to users from different regions, thereby enhancing usability and user experience. In this assignment, the aim is to modify a starter code snippet to incorporate different locale settings for formatting numeric data, currency, and dates. The code initially uses default locale settings but is incomplete, with placeholders indicating where specific locale information should be inserted. By completing these sections, students will learn how to leverage the Locale class effectively and understand its application in data formatting. Using Locale for Number and Currency Formatting The first task is to instantiate a Locale object representing a specific geographical region. For example, to format data according to French conventions, students can use Locale.FRANCE. Similarly, other predefined constants such as Locale.US or Locale.JAPAN can be employed to demonstrate regional differences. Once the locale object is created, it can be used with the NumberFormat.getInstance(Locale) method to format numbers, or with NumberFormat.getCurrencyInstance(Locale) to format currency values. Embedding comments in the code helps clarify how these methods utilize the locale to produce region-specific formats. Retrieving Currency Details The program also requires fetching currency information based on a specific country. Using the Currency.getInstance() method, students should pass a Locale object that corresponds to a known country or their own choice. The returned Currency object has getDisplayName(), getCurrencyCode(), and other methods to retrieve human-readable names and symbols that reflect regional currency co
