In java language Class Design – Date V0.0 & V1.0 Create a new project for this lab and create a new class inside called Date. If you created a Date class last week, you may use it as a base. What does it mean to be a Date? What data items (called "state") do you need to keep track of? Alternatively, what does a date have? ("has a" == composition) What can a Date do? What are the actions and verbs that can be applied to a date? Come up with one or two. These become the class’s methods. Try adding 3 data items to your Date to manage the month, day and year. Should these be local variables? Class-level (or instance) variables? Now let’s build a method to set the date This function should take 3 integers as input and assign these to your instance variables declared in the previous step. public void setDate(int m, int d, int y) { And, let’s build a method to report the date This function takes no input and uses the console to output the Date in the format...

Create an Empty Activity Project to implement the following Layouts. Layouts: one Text, one E-mail, one Image and one Button. Tips: - The project’s layout structure is ConstraintLayout. - The first element is Text. You must write your name in place of "XYZ" with a textSize = 20sp and textColor of Red. - The second element is E-mail. You must write your email address under your name, with the textColor = Blue. - The third element is an image. You can add any image after your name and email with any size you like. - The fourth element is a button. Place the button on the end of the page and call it "OK". Implement the previous requirements and include the XML file and screenshot of the layout’s output, after you run the application. Layout’s output:

Java Program - GUI Number Guessing Look at the code, notice that the actionPerformed method is not complete. It just contains code that will print to the console when buttons are pressed. Make the following modifications to the code. When the Higher button is pressed invoke this.guesser.higher(), and then put the new guess into the this.guessField When the Lower button is pressed invoke this.guesser.lower() and then put the new guess into the this.guessField When the Reset button is pressed, invoke this.guesser.reset() and then put the new guess into the ghis.guessField When the Correct button is pressed, exit the app using System.exit(0). Wrap the invocation of lower() and higher() in try catch blocks that catch NumberGuesserIllegalStateExceptions. Show a JOptionPane that alerts the user that you are onto their schemes. Change the guessing algorithm from random-guess to binary search. You can do this by changing the object created for the guesser to a plain old NumberGuesser. It...

Define the following methods: computeBaseArea() has one double parameter as a cylinder's radius. The method returns the area of the cylinder's base as a double. The area of the base is calculated by: ���� = � ∗ ������2 computeSurfaceArea() has two double parameters as a cylinder's radius and height. The method returns the cylinder's surface area as a double, and uses the computeBaseArea() method to calculate the cylinder's base area. The surface area is calculated by: ������� ���� = (2 ∗ ���� ����) + (2 ∗ � ∗ ������ ∗ h���h�) Click here for example Note: Use Math.PI for �. 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 public class CylinderCalculations { /* Your code goes here */ publicstaticvoidmain(String[] args) { Scannerscan=newScanner(System.in); doublecylinderRadius; doublecylinderHeight; cylinderRadius=scan.nextDouble(); cylinderHeight=scan.nextDouble(); System.out.println("Cylinder radius: "+cylinderRadius);...

For each of the operators and methods listed above, explain what they do (experiment with code in Python, DON’T LOOK IT UP, and be sure to turn in the code that you used to figure it out (use comments to tell us which method or operator you are figuring out in each part of your code). • my_list.count(VALUE) • my_list.pop(VALUE) • my_list.reverse() • my_list.append(NEW_value) • my_list + my_next_list • len(my_list) 2- Explain what the following piece of code do. Write your answer in comments. my_list= ["twinkle", "twinkle", "little", "star", 4] print(my_list[slice(0, 3, 2)])

Using DrawingPanel.java (from chapter 3G), draw a grid for filling in a 4 x 4 square of cell containing integers. For this part of the assignment the values are not important, but you are welcome to use the values shown in the magic square from below. Note that the values in any horizontal row, vertical column or main diagonals add up to 34, in addition to various sub-squares in the larger square also add up to the same value. Requirements: The magic square should be centered in the panel The values in each of the cells should be centered in that cell (both horizontally and vertically). You can assume the values will be <= 99 (i.e., at most 2 digits). For this part of the assignment, you can hard-code the values; you will store them in a 2-dimensional array (from chapter 7) when implementing Part B of the assignment. The title "CSC 142 Magic Square" is centered horizontally in the panel and at y = 50 You are free to choose the colors, fonts, font sizes and effects. This is what I used...
