Answer:

To tell what will happen when an if-statement is false

Explanation:

We use else statement if if-statement get false.

for example

if(a>20)

{

print "your age is greater than 20"

}

else

{

print "Your age is less than 20"

}

In the pseudo code, you see the use of else statement, that if age is greater than 20 then display message "you are age is greater than 20". if this statement get false, i.e. you are age is not greater than 20 then else statement will be executed and message will be displayed that your age is less than 20.

Why other option are not correct

To input a variable:

to get input, we use input statement of respective programming language not if-else statement.

To end an if statement

we don't use else statement to end if statement. when condition met then if statement will be ended

To handle string value

we use input validation statement to handle if statement.

artcher [175]

Answer:

Java variable is the name of a group of data value stored in memory that can change its value but cannot change its type during the program's execution

Explanation:

Generally, a variable is a temporary location in the memory where data are stored in a computer program. Values in the variable can always be change during the course of program execution.

The equal sign ( = ) is use to assign and identify a variable. The value to be stored in the variable is always at the right of the equal sign, while the variable name is always at the left of the equal sign.

84.6% complete question a network administrator is installing a device that uses redundant array of independent disks (raid) tec

Alja [10]

The device that this network administrator is most likely installing in the infrastructure is a Network Attached Storage (NAS).

<h3>What is a Network Attached Storage (NAS)?</h3>

A Network Attached Storage (NAS) can be defined as a file-dedicated storage device that is designed and developed to enable multiple end users and other heterogeneous client devices to store, share and retrieve data anywhere from a centralized disk, especially through a network.

In this context, we can infer and logically conclude that a Network Attached Storage (NAS) is the device that this network administrator is most likely installing in the infrastructure because it doesn't require licensing and the data stored on it at the file level can be accessed anywhere.

Write a Comparator that compares String objects by the number of words they contain. Consider any nonwhitespace string of charac

Readme [11.4K]

Answer:

import java.util.Scanner;

public class num12 {

public static void main(String[] args) {

Scanner in = new Scanner(System.in);

System.out.println("Enter the first String");

String word1 = in.nextLine();

System.out.println("Enter the second String");

String word2 = in.nextLine();

System.out.println("Enter the third String");

String word3 = in.nextLine();

//Remove all white spaces

String cword1 = word1.replace(" ","");

String cword2 = word2.replace(" ","");

String cword3 = word3.replace(" ","");

//Comparing the string by their lengths

if(cword1.length()>cword2.length()&&cword1.length()>cword3.length()){

System.out.println(word1+" Is the longest");

}

else if(cword2.length()>cword1.length()&&cword2.length()>cword3.length()){

System.out.println(word2+" Is the longest");

}

else{

System.out.println(cword3+" Is the longest");

}

Explanation:

Using Java Programming Language

Use the Scanner Class to obtain the String values from the user

Save them in different variables

Use the replace() method in java to remove white space from any of the string entered

Using if and else statements compare the lengths of the strings (word.length()) returns the length of the word.

Print out the word that is longest

NOTE I have compared three Strings, comparing two would have been more straigth forward

If x has a value of 7 and y has a value of 20, what is displayed as a result of executing the code segment

Llana [10]

6.65 is displayed as the output of the block of code

In python programming, * denotes multiplication. To get the output, we will substitute the value of x and y given into the result to have;

result = x * y - x / (y)

result = 7 * 20 - 7 / (20)

result = 140 - 7 / (20)

result = 133/20

result = 6.65

This shows that 6.65 is displayed as the output of the block of code

The question is incomplete;

Let the code segment be

>>> x = 7

>>> y = 20

>>> result = x * y - x / (y)

>>> result

output:__?
