Answer:

No, Only the value between 100 and 200 can not test the code correctly.
This code snippet ensures that the cost value is between 100 and 200.

Explanation:

The above code has three condition test- if, else-if and else.
The first condition is true for the value which is a minimum of 100.
The else if condition is true for the value which is maximum from 200.
Then the else condition is used when the if and else if condition is false.
when the user gives the value between 100 and 200 then it will test that the value lies between 100 or 200.
To test the whole scenario there must be one value is less than 100 and greater than 200.

If Seneca has not done anything since the conditional formatting she can undo what her last action was. This is done by either pressing control+Z or by clicking on the undo icon.

If other actions have been done, there are a few more steps that need to be taken in order to clear the formatting. They are:

1. Select the cell or cells whose formatting you want to delete.

2. Display the Home tab of the ribbon.

3. In the Editing group, click Clear | Clear Formats.

Write an application that throws and catches an ArithmeticException when you attempt to take the square root of a negative value

lozanna [386]

The code for the program described in question:

import java.util.Scanner;

public class Test {

public static void main(String[] args) {

double number;

double squareRootOfNumber;

String userInput = null;

Scanner scanner = new Scanner(System.in);

System.out.println("Enter the number: ");

userInput = scanner.next();

number = Double.parseDouble(userInput);

squareRootOfNumber = Math.sqrt(number);

if (number < 0) {

throw new ArithmeticException("Can't take square root of negative number");

}

System.out.format("Square root of number entered is %.2f %n", squareRootOfNumber);

}

The output of the program will be:

Enter the number:

-90

Exception in thread "main" java.lang.ArithmeticException: Can't take square root of negative number at com.brainly.ans.Test.main(Test.java:18)

Explanation:

Function from standard Java library java.lang.Math.sqrt will not throw an ArithmeticException even its argument is negative so there is no reason to surround your code try/catch block.

Instead, we have thrown ArithmeticException manually by using throw keyword:

throw new ArithmeticException("Can't take square root of negative number");

If a filesystem has a block size of 4096 bytes, this means that a file comprised of only one byte will still use 4096 bytes of s

jenyasd209 [6]

Answer:

Python code given below

Explanation:

def calculate_storage(filesize):

block_size = 4096

full_blocks = filesize // block_size

partial_block = filesize % block_size

if partial_block > 0:

return (full_blocks + 1) * block_size

return filesize

print(calculate_storage(1))

print(calculate_storage(4096))

print(calculate_storage(4097))
