Define a new object in variable painter that has properties "name" storing "Vincent van Gogh"; "artworks" storing "The Starry Ni

trapecia [35]

Answer:

painter = {'name' : "Vincent van Gogh", 'artworks': ["The Starry Night","Irises","The Potato Eaters"],'bornDate': "March 30, 1853", 'eyeColor': "July 29, 1890", 'diedDate': "July 29, 1890"} #this is a code which holds the questions defined value in a painter variable.

Explanation:

The above question wants to declare a variable that is in the form of a key and value pair.
The above question states to define name, artworks,eyeColor, and dieddate as a key and the other is defined as a value.
when a user wants to access the whole dictionary then he can do with the help of the painter variable.
But when he wants to access the value of any particular key, then he can do it with the help of the key name as "painter[keyname]".

Does the submission include the file "SuperPower.java"? Does the file include a public class called "SuperPower"? Does the class

Oduvanchick [21]

Answer:

Here is the program fulfilling all the requirements given:

import javax.swing.JOptionPane;

public class SuperPower{

public static void main(String[] args) {

String power;

power = JOptionPane.showInputDialog("What is your super power?");

power = power.toUpperCase();

JOptionPane.showMessageDialog(null, power);} }

Explanation:

Does the file include a public class called "SuperPower"

See the statement:

public class SuperPower

Does the class include a public method called "main"? Is the "main" method static?

See the statement:

public static void main(String[] args)

Does the main method have a String assignment statement that uses "JOptionPane.showInputDialog"

See the statement:

power = JOptionPane.showInputDialog("What is your super power?");

Does the main method have a statement that uses "JOptionPane.showMessageDialog"?

See the statement:

JOptionPane.showMessageDialog(null, power);

Does the program convert the String from "JOptionPane.showInputDialog" using the "toUpperCase" method?

See the statement:

power = power.toUpperCase();

Does the submission include a screenshot that shows an Input dialog that asks, "What is your superpower?" Does the submission include a screenshot that shows a Message dialog stating " TO THE RESCUE!", where "" is the input converted to upper case?

See the attached screenshots

If the program does not let you enter an exclamation mark after "to the rescue" then you can alter the code as follows:

import javax.swing.JOptionPane;

public class SuperPower{

public static void main(String[] args) {

String power;

power = JOptionPane.showInputDialog("What is your super power?");

power = power.toUpperCase();

JOptionPane.showMessageDialog( null, power+"!");} } // here just add an exclamation mark which will add ! after the string stored in power

An aviation tracking system maintains flight records for equipment and personnel. The system is a critical command and control s

sergeinik [125]

Answer:

offline backup solution

Explanation:

In such a scenario, the best option would be an offline backup solution. This is basically a local and offline server that holds all of the flight record data that the cloud platform has. This offline backup server would be updated frequently so that the data is always up to date. These servers would be owned by the aviation company and would be a secondary solution for the company in case that the cloud platform fails or the company cannot connect to the cloud service for whatever reason. Being offline allows the company to access the database regardless of internet connectivity.

When a visitor clicks the submit button on a form, the ______ of each form element is sent?

Bond [772]

In data presentation of computing systems and applications, when a user click the submit button on the form, the name-value pair of each form is sent because it is an open-ended data structure that allows future extension without altering existing code or data.

Write the 8-bit signed-magnitude, two's complement, and ones' complement representations for each decimal number: +25, + 120, +

pshichka [43]

Answer:

Let's convert the decimals into signed 8-bit binary numbers.

As we need to find the 8-bit magnitude, so write the powers at each bit.

Sign -bit 64 32 16 8 4 2 1

+25 - 0 0 0 1 1 0 0 1

+120- 0 1 1 1 1 0 0 0

+82 - 0 1 0 1 0 0 1 0

-42 - 1 0 1 0 1 0 1 0

-111 - 1 1 1 0 1 1 1 1

One’s Complements:

+25 (00011001) – 11100110

+120(01111000) - 10000111

+82(01010010) - 10101101

-42(10101010) - 01010101

-111(11101111)- 00010000

Two’s Complements:

+25 (00011001) – 11100110+1 = 11100111

+120(01111000) – 10000111+1 = 10001000

+82(01010010) – 10101101+1= 10101110

-42(10101010) – 01010101+1= 01010110

-111(11101111)- 00010000+1= 00010001

Explanation:

To find the 8-bit signed magnitude follow this process:

For +120

put 0 at Sign-bit as there is plus sign before 120.

Put 1 at the largest power of 2 near to 120 and less than 120, so put 1 at 64.

Subtract 64 from 120, i.e. 120-64 = 56.

Then put 1 at 32, as it is the nearest power of 2 of 56. Then 56-32=24.

Then put 1 at 16 and 24-16 = 8.

Now put 1 at 8. 8-8 = 0, so put 0 at all rest places.

To find one’s complement of a number 00011001, find 11111111 – 00011001 or put 0 in place each 1 and 1 in place of each 0., i.e., 11100110.

Now to find Two’s complement of a number, just do binary addition of the number with 1.
