Define data encapsulation, and why you would want to use it.
Step by step
Solved in 3 steps
- How does data encapsulation work, and when would you want to utilize it?What exactly is data encapsulation, and why would you want to utilize it?JAVA Script Create a form that has a last name, a first name, an email address, a drop-down listing of 10 cities in Massachusetts. The list is to be sorted (hint: think array), an email address, and a zip code field. Each field is to be process through a validation function. You may use one function for each but if you are creative you should be able to use just one function. The drop-down listing will not require validation because they will be choosing from a list that you are providing. This input from must be styled and show an effect to the user as to which field that are currently providing input.
- NO CODE, ESSAY ONLY. EXPLAIN. Develop a program that implements any of the indexing types. Use methods to organize your code and do not forget to follow naming conventions.Q1: What are some features and benefits to structured data? Check all that apply. Group of answer choices A method can be passed a structure and the method can then process multiple data items in a structure. 1: Related data items can be under 1 structure definition. 2: Programmers can code structures as they see fit. 3: Structures can be used in arrays to simplify some programming tasks. 4: Multiple variables can be defined using the same structure. Q2: Enumerations are representing constant values and are therefore required to be coded in uppercase characters. True False Q3: Enumerations are stored in memory as ______ . Group of answer choices Integer 1: String 2: Pointer to an internal variable 3: Internal array Q4: Why did the author include enumerations in the same chapter as structured data? Check all that apply. 1: Enumerations are a programmer-defined data type, similar to structured data types being programmer-defined. 2: You can't have structured…In this section, you will provide instances of data that is appropriate for display in three dimensions.
- How do data dictionaries aid in mapping dependencies between data elements?Consider the following scenario: you're creating a Java application to store the names and ages of a family's children. Describe the strategy you would use in order to determine the data types that would be necessary for your particular application. You must provide three (3) data components and the data types that correspond to them for your application. Justify your response with a specific reason.Software development C#The application developed in Part 1 is already useful in terms of functionality, but it has a severe usability flaw: the data is not persisted, forcing the user to capture all the data from scratch if the application is executed again.For this part, you will continue working on the application you developed in Part 1. Remember to implement any feedback provided by your lecturer on Part 1 before working on Part 2. Marks will be awarded for this (see the rubric for details).All the requirements from Part 1 must still be met by the program, with the following changes and additions:1. The software shall persist the data in a SQL database.2. The user shall be able to register with a username and password.3. The software shall store only the hash of the password in the database.4. The user shall be able to log into the software with their username and password.5. The user shall only be able to see their own data and never that of other users.Non‐functional…
