Answer:

Explanation:

The following code is written in Java and it simply creates the 2-Dimensional int array with the data provided and then uses the Arrays class to easily print the entire array's data in each layer.

import java.util.Arrays;

class Brainly {

public static void main(String[] args) {

int[][] arr = {{16, 17, 14}, {17, 18, 17}, {15, 17, 14}};

System.out.print(Arrays./*Remove this because brainly detects as swearword*/deepToString(arr));

}

Evaluate the expression. Be sure to list a value of appropriate type (e.g., 7.0 rather than 7 for a double, Strings in quotes).

<h2>Answer:</h2>

14.0

<h2>Explanation:</h2>

Using the level of precedence in Java,

From left to right;

(i) the first division operation will be done.

(ii)followed by the second division operation.

(iii)followed by the first multiplication operation.

(iv)followed by the third division operation.

(v)followed by the second multiplication operation.

(vi) followed by the first addition operation.

(vii)lastly followed by the second addition operation.

=================================================

Taking the steps above one after the other;

(i) the first division operation will be done (i.e 19 / 2)

=> Integer division in Java gives an integer result. Therefore, 19 / 2 = 9.5 will give 9.

So,

=> 19 / 2 / 2.0 + 2.5 * 6 / 2 + 0.5 * 4

=> 9 / 2.0 + 2.5 * 6 / 2 + 0.5 * 4

(ii)followed by the second division operation. (i.e 9 / 2.0)

=> From the result from step (i), the second division operation is now 9 / 2.0.

=> 9 / 2.0 = 4.5

So,

=> 9 / 2.0 + 2.5 * 6 / 2 + 0.5 * 4

=> 4.5 + 2.5 * 6 / 2 + 0.5 * 4

(iii)followed by the first multiplication operation. (i.e 2.5 * 6)

=> The first multiplication operation is given by 2.5 * 6

=> 2.5 * 6 = 15.0

So,

=> 4.5 + 2.5 * 6 / 2 + 0.5 * 4

=> 4.5 + 15.0 / 2 + 0.5 * 4

(iv)followed by the third division operation. (i.e 15.0 / 2)

=> The third division operation is given by 15.0 / 2

=> 15.0 / 2 = 7.5

So,

=> 4.5 + 15.0 / 2 + 0.5 * 4

=> 4.5 + 7.5 + 0.5 * 4

(v)followed by the second multiplication operation. (i.e 0.5 * 4)

=> The second multiplication operation is given by 0.5 * 4

=> 0.5 * 4 = 2.0

So,

=> 4.5 + 7.5 + 0.5 * 4

=> 4.5 + 7.5 + 2.0

(vi) followed by the first addition operation. (i.e 4.5 + 7.5)

=> The first addition operation is given by 4.5 + 7.5

=> 4.5 + 7.5 = 12.0

So,

=> 4.5 + 7.5 + 2.0

=> 12.0 + 2.0

(vii) lastly followed by the second addition operation. (i.e 12.0 + 2.0)

=> The second addition operation is given by 12.0 + 2.0

=> 12.0 + 2.0 = 14.0

So,

=> 12.0 + 2.0

=> 14.0

Therefore, 19 / 2 / 2.0 + 2.5 * 6 / 2 + 0.5 * 4 = 14.0

In Java, the order of precedence for arithmetic operators is;

=> /, * and %

=> followed by + and -

Which of the following is the safest authentication method?

myrzilka [38]

The safest authentication method is authentication using a smart card.

Smart Card Authentication uses a physical card along with a smart card reader and software on the workstation to validate users into enterprise resources like workstations and applications. Although smart card authentication offers a terrible user experience and is expensive to deploy and maintain, it is very secure.

Because smart card authentication requires a physical credential, a hardware card reader, and software, it is expensive and difficult to administer. Smart cards are only used in the most secure workplaces, such as three-letter agencies of the federal government or privileged access at a financial institution, as these environments frequently forbid employees from carrying smartphones to and from work.

Write a function called which_vowels_present that takes a single string parameter. Complete the function to return a list of str

romanna [79]

Answer:

import java.util.ArrayList;

import java.util.List;

public class Vowels {

public static void main(String[] args) {

String word = "I am David from Nigeria";

System.out.println(which_vowels_present(word));

}

public static List which_vowels_present(String enteredWord){

List<Character>list = new ArrayList<>();

String word = enteredWord.toLowerCase();

for (int i =0; i<word.length(); i++){

if (word.charAt(i) == 'a' || word.charAt(i) == 'e' || word.charAt(i) == 'i'

|| word.charAt(i) == 'o' || word.charAt(i) == 'u') {

list.add(word.charAt(i));

}

return list;

}

Explanation:

Using Java programming Language
Import java.util.ArrayList; and java.util.List
Create the method which_vowels_present which accepts a string parameter
Within the method create a list object
Use a for loop to iterate the string. within the for loop use an if statement to check individual characters of the string if any is a vowel, add it to the list
return the list
In the main method, create a test string, call the method and pass the string as parameter
