Write a complete interactive program that displays the alphabet on the canvas. Each time the user presses a letter key, the matching letter should get a little big bigger. • When the user presses the ENTER or RETURN keys (you can use Processing's RETURN and ENTER values to detect this), the letters should be reset to their initial size Make sure your program doesn't crash if a non-letter key, like a number or punctuation, is pressed. Hint: You might be tempted to do this "the long way", with 26 different variables and 26 if/elif statements under your keyPressed() function. Don't do that. Use a dictionary to store the count/size of each letter. If you do this nicely, your code will be short. Our solution is only 29 lines (including blank lines and function headers!). Example 1: Initial state O alphabet a b c d e f klmnopq r s t u v w x Example 2 - After pressing the 'c'. 'o' and 'k' keys a few times Cdefghijklmn Op q r S

can you solve this please? Adopt appropriate Java animation code to implement the video in the file “test4.wmv” and given that the parametric equation for a circle. x=r*cos(t) y=r*sin(t) with t in range [0, 2p] and r is the radius of the circle.

Write a program that moves the ball in a pane. You should define a pane class for displaying the ball and provide the methods for moving the ball left, right, up, and down. Check the boundary to prevent the ball from moving out of sight completely.
You are to write a program that allows the user to draw a simple house using 5 mouse clicks. - The first two clicks will be the opposite corners of the rectangular frame of the house. - The third click will indicate the center of the top edge of the rectangular door. The door should have a total width that is 1/5 of the width of the house frame. The sides of the door should extend from the corners of the top down to the bottom of the frame. - The 4th click will indicate the center of a square window. The window is as wide as the door. (A change from the original book program.) - The last click will indicate the peak of the roof. The edges of the roof will extend from the point at the peak to the corners of the top edge of the house frame. Make the lines of the roof edge green. (Another change from the original book program.)
Write a program that displays twocircles with radius 10 at location (40, 40) and (120, 150) with a line connectingthe two circles, as shown in Figure . The distance between the circlesis displayed along the line. The user can drag a circle. When that happens, thecircle and its line are moved, and the distance between the circles is updated.
1). Write a java program that use the Canvas class to produce patterns by updating the code below. Where appropriate, use this.getWidth() and this.getHeight() so that the output will looks the same regardless of the window size. Use fill rectangle commands to produce/draw flag of France. The vertical stripes are same (blue, white, red), they are of the same size, and the same width as well. import java.wat.; import javax.swing.JFrame; public class DisplayGraphics extends Canvas { public static void main (String [] args) { DisplayGraphics m=new DisplayGraphics(); jFrame f=new JFrame (); f.add(m); f.setSize (400,400); f.setVisible (true); public void paint (Graphics g) { g.setColor(Color.blue) g.drawRec(400, 400, 100, 50); g.fillRec(400, 0, 100, 50); g.setColor(Color.white); g.drawRec(400, 400, 100, 50); g.fillRec(); g.setColor(Color.red); g.drawRec(400, 400, 100, 50); g.fillRec(); } 2).

Add a new Java class to your project by right clicking on the src folder in the Project pane and select New > Java Class.Enter Hours as the name for this class, and IntelliJ will add it to the files in the src folder for your project. Remember tocopy and insert the standard heading for the main method as you did for Program 2.Write a program that prompts the user to enter a number of hours, and produces the equivalent number of days as a wholenumber along with the number of hours left over. Assume that a day has exactly 24 hours. The following example showsthe format to use for your output, where the input entered by the user is underlined.Enter the number of hours: 100100 hours is 4 days, plus 4 hours.Define Variables: The number of hours will be a whole number, and we would like to obtain results as whole numbers ofdays and hours, so use the int data type to declare the variables to hold the numbers of hours input, as well as the results(the number of days and number of hours left…
