Python:
Write a code snippet that imports the tkinter library and creates a new window object root.
Add a label widget to the window object root with the text "Hello, World!".
Write a code snippet that adds a button widget to the window object root with the text "Click me!", and binds the button to a function button_click() that prints "Button clicked!" to the console.
Hint: You may find the Label, Button, and command attributes in tkinter useful for completing parts 2 and 3
Note: For each part of the question, make sure to provide clear instructions and examples for the code snippets. Also, make sure to test your code snippets to ensure that they work as intended.
Create a sample program that uses type conversion
and scanner class.
Create a PHOTO ESSAY that shows how you are using
the type conversion and Scanner class in java.
Include at least 7 pictures with 30 to 50 words caption
each.
Write a Java program StringApplication which creates a Scanner object then does the
following:
1. Ask the user to enter a book title using prompt "Enter a book title: "
2. Read in the book title
3. Print the first character of the book title within single quotes.
4. Print the first word of the book title within double quotes.
5. Print the rest of the book title without the space after the first word within double quotes
6. Ask the user to enter the starting position for a substring
7. Read in the starting position and store it in an integer variable
8. Ask the user to enter the length for the substring
9. Read in the length and store it in an integer variable
10. Print the substring of the book title specified by the starting position and the length within
double quotes
There is no starter code. You can have local variables as needed but should create just one
Scanner object.

- the AFMotor library installed, launch the Arduino IDE. Let's write a sketch that will test the stepper motor. The code will do the following: 1. Load the AFMotor library. 2. Create an AFMotor stepper motor object and set the stepper's connection and steps per revolution (i.e., how fast the stepper motor's shaft rotates). 3. Move the shaft clockwise and counterclockwise using the stepper motor's two coils. By the way, this action is known as double-coil activation, and it produces greater torque compared to using just a single coil at a time. We will need that extra torque to move the curtain string.arrow_forwardusing java (Use the Date class) Write a program that creates a Date object, sets its elapsedtime to 10000, 100000, 1000000, 10000000, 100000000, 1000000000,10000000000, and 100000000000, and displays the date and time using thetoString() method, respectively.arrow_forwardCreate a Java application which will take an infix algebraic expression as an input from user.

- Create an application in Java that uses card layout with three cards. The first card - a login card - should have two text fields, one for username and other for password. There are two users - Bob and Fred - whose passwords are "mubby and "goolag" respectively. If Bob logs in, switch to a card - the bob card - that has a text field, a text area and two buttons. If the first button is pressed, get the text from the text field and append it to the text area. If the second button is pressed, return to the login card. If Fred logs in, switch to a card - the fred card - that has three buttons. If the first button is pressed, change the background color to green. If the second button is pressed, change the background color to red. If the third button is pressed, return to login card.arrow_forwardCreate a simple guessing game, similar to Hangman, in which the user guessesletters and then attempts to guess a partially hidden phrase. Display a phrase inwhich some of the letters are replaced by asterisks: for example, G* T*** (for GoTeam). Each time the user guesses a letter, either place the letter in the correctspot (or spots) in the phrase and display it again or tell the user the guessed letteris not in the phrase. Display a congratulatory message when the entire correctphrase has been deduced. Save the game as SecretPhrase.java. In the nextchapter, you will modify this program so that instead of presenting the user withthe same phrase every time the game is played, the program randomly selects thephrase from a list of phrases. Professor's note: "HINT on Lab #4 : Be sure to check for UPPER & LOWER Case entries from the User when they enter guessed characters for your phrase."arrow_forwardWrite an Java application that determines whether a phrase entered by the user is a palindrome. A palindrome is a phrase that reads the same backward and forward without regarding capitalization or punctuation. For example, “Dot saw I was Tod”, “Was it a car or a cat I saw?”, and “Madam, I’m Adam” are palindromes. Display the appropriate feedback: You entered a palindrome or You did not enter a palindrome. import java.util.*; public class Palindrome { public static void main(String[] args) { // Write your code here } }arrow_forward
- Using the Circle2D class you defined in Exercise 8.18, write a program that enables the user to specify the location and size of two circles and displays whether the circles intersect, as shown in Figure 12.20. Enable the user to point the mouse inside a circle and drag it. As a circle is being dragged, the program updates the circle’s center coordinates and its radius in the text fields.arrow_forwardCode with comments and output screenshot is must for an Upvote.
