Create an interface called Runner. The interface has an abstract method called run() that displays a message describing the meaning of run to the class. Create classes called Machine, Athlete, and PoliticalCandidate that all implement Runner.
The run() should print the following in each class:
Machine - When a machine is running, it is operating.
Athlete - An athlete might run in a race, or in a game like soccer.
PoliticalCandidate - A political candidate runs for office.
----------------------------------------------------------------------------------------------------
public class Athlete implements Runner
{
public void run()
{
// write your code here

public class DemoRunners
{
public static void main(String[] args)
{
Machine runner1 = new Machine();
Athlete runner2 = new Athlete();
PoliticalCandidate runner3 = new PoliticalCandidate();
runner1.run();
runner2.run();
runner3.run();

Answer:
Please find the code and its output in the attached file.
Explanation:
In the above-given code, an interface "Runner" is defined, inside the interface, an abstract method run is declared.
In the next step, three class "Athlete, Machine, and PoliticalCandidate" s defined that implements the run method, and use the print message that holds a given value as a message.
In the next step, a class "DemoRunners" is defined, and inside the main method, the three-class object is declared, which calls the run method.

802.11ac provides an advantage over 802.11n by incorporating increased channel bonding capabilities. What size bonded channels does 802.11ac support?
Answers
Answer:
The 802.11ac wireless standard takes channel bonding to a higher level because it can support 20MHz, 40MHz, and 80MHz channels, with an optional use of 160MHz channels.
Explanation:
The 802.11ac is a standardized wireless protocol established and accepted by the institute of electrical and electronics engineers (IEEE). 802.11ac as a wireless local area network (WLAN) protocol, has multiple amplitude and bandwidth, thus making it to be the first standard wireless protocol to have the ability to operate on a Gigabit (Gb) network.
Generally, the 802.11ac wireless standard provides an advantage over 802.11n by incorporating increased channel bonding capabilities. The 802.11ac wireless standard takes channel bonding to a higher level because it can support 20MHz, 40MHz, and 80MHz channels, with an optional use of 160MHz channels.
On the other hand, 802.11n is a standardized wireless protocol that can support either a 20MHz or 40MHz channel.
A bank has three types of accounts: checking, savings, and loan. Following are the attributes for each type of account:
CHECKING: Acct No, Date Opened, Balance, Service Charge
SAVINGS: Acct No, Date Opened, Balance, Interest Rate
LOAN: Acct No, Date Opened, Balance, Interest Rate, Payment
Assume that each bank account must be a member of exactly one of these subtypes. Using generalization, develop an EER model segment to represent this situation using the traditional EER notation, the Visio notation, or other tools like Lucidchart / Draw.io. Remember to include a subtype discriminator.

Explanation:
Description of the model:
Generalization is the method used here just for the EER model, which sweeping generalization is a way to identify the common characteristics of a sequence to create a common entity. This is an approach from the bottom up. Its verification, savings, and credit firms are extended to a higher-level object's account. So, the entity entities (Account) are the common traits of these bodies. As well as the specific qualities are the part of specialized entities (checks, savings, and loans). This EER model is shown via the subgroup and supertype notes. The Balance has calculated the distance, throughout the entity type entity are key patterns of the subgroup entities. The wood beaded includes Acct No, Balanced and Open Date. The key was its underliner Acct No. the very first key. CHECKING, SAVINGS, and LOAN are the subsection organizations of the Supertype Account.Its subtypes get the traits that are not normal. It Testing feature is the uncommon extra fee feature. Its SAVINGS post-type feature has the peculiar exchange rate feature. Its LOAN subgroup feature produces unusual interest in fixed payment characteristics.Enhanced Entity relationships[EER] represent the requirements and complexities of a complex database.
What is Enhanced Entity-relationship?Here, the account entity generalized into three entities and these are checking, savings, and loan.
Also, the common attribute the three of them have can be considered in the account entity which is common in them while the individual attributes must be specified under its own entity.

In __________ write, the data are stored in the cache, and control returns to the caller. Select one: a. a synchronous b. a buffered c. an asynchronous d. a non-buffered
Answers
Answer:
The correct answer to the question is option C (an asynchronous)
Explanation:
Computer store files in its temporary data storage space so as to facilitate easy retrievals when needed. Cache memory is in the temporary data storage space of the computer, faster than any other system memory so that when the processor requests information from the computer memory after a user place a command, the cache memory makes the information available in a short time when the data are required eliminating delay when ram will have to take time to fetch the data to provide to the processor.
In an asynchronous write, the data are stored in the cache to enable easy retrieval by the computer processor just as the cache is explained above, it allows writing data to the cluster. Asynchronous write also allows control returns to the caller.

sum_even Write a program that reads an integer 0 < n < 2^32, returns the sum of all digits in n that are divisible by 2. For example, if n = 341238 the output would be 14, because it is the sum of 4 + 2 + 8. Hint: a signed int may not be enough.
Answers
Answer:
Written in Python
n = int(input("Num: "))
sum_even = 0
if n > 0 and n < 2**32:
strn = str(n)
for i in range(0,len(strn)):
if int(strn[i])%2 == 0:
sum_even = sum_even+ int(strn[i])
print(sum_even)
Explanation:
This line prompt user for input
n = int(input("Num: "))
This line initializes sum_even to 0
sum_even = 0
This line checks for valid input
if n > 0 and n < 2**32:
This line converts input to string
strn = str(n)
This line iterates through each digit of the input
for i in range(0,len(strn)):
This if condition checks for even number
if int(strn[i])%2 == 0:
This adds the even numbers
sum_even = sum_even+ int(strn[i])
This prints the sum of all even number in the user input
print(sum_even)
Adjust list by normalizing When analyzing data sets, such as data for human heights or for human weights, a common step is to adjust the data. This can be done by normalizing to values between 0 and 1, or throwing away outliers. For this program, adjust the values by subtracting the smallest value from all the values. The input begins with an integer indicating the number of integers that follow. Assume that the list will always contain fewer than 20 integers. Ex: If the input is: 5 30 50 10 70 65 the output is: 20 40 0 60 55 The 5 indicates that there are five values in the list, namely 30, 50, 10, 70, and 65. 10 is the smallest value in the list, so is subtracted from each value in the list. For coding simplicity, follow every output value by a space, including the last one.

Memory locations in personal computers are usually given in hexadecimal. If a computer programmer writes a program that requires 100 memory locations, determine the last memory location that is used if the program starts at location 2C8DH 16 hexadecimal
Answers
Answer:
The answer is "The last memory addresses used by a specific program is 2CF0".
Explanation:
For this specific problem, we assume that only a memory storage allocation like Array data structure is needed, as well as any allocation only needs one memory cell since it focuses on the structure and type of data used.
So, first, we will transform the provided memory address for better comprehension from Hexadecimal into decimal.
[tex]\to \bold{(2C8D)_{16} = (11405)_{10}}[/tex]
Now 11405 is the first memory cell's address. With all of this number, it can add 99, resulting in the final decimal memory address.
[tex]=11405 + 99\\\\= 11504[/tex]
[tex]\bold{(11504)_{10} = (2CF0)_{16}}.[/tex]
