Transcribed Image Text: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!).

- Modify the Dice Poker program from this chapter to include any or all of the following features: 1- Splash Screen. When the program first fires up, have it print a short introductory message about the program and buttons for "Let's Play" and "Exit." The main interface shouldn't appear unless the user se- lects "Let's Play." 2-Add a "Help" button that pops up another window displaying the rules of the game (the payoffs table is the most important part). 3-Add a high score feature. The program should keep track of the 10 best scores. When a user quits with a good enough score, he/she is invited to type in a name for the list. The list should be printed in the splash screen when the program first runs. The high-scores list will have to be stored in a file so that it persists between program invocations.arrow_forwardWrite a program that will use WheelsFX shapes to create a Car. There is a size requirement; the Car should fit inside the box that appears on the start-up program. You will be able to change or refine your car over the next several assignments if you so choose. Be creative, your Car can also be something purely out of your imagination if you so choose. Pick one of your shapes. In English, what will you need to do to take it from the default that we get when we create the shape to what you need to build that part of your Car? Now take the shape that you wrote out in question 2 and now write what the Java code would be. Pretend that you were writing this program in C++ instead of Java. Take the code you wrote in question three and now re-write it to look like it would in C++. For the object, you must use a pointer variable. Looking at your answers for questions three and four, what differences do you see syntactically? What does this mean going forward for other objects we work with? The…arrow_forwardThis method returns a string where a triangle appears on the left size of the diagram, followed by horizontal lines. For example calling DrawingApp.getFlag(9, ‘R’, ‘.’, ‘Y’); will generate the stringarrow_forward
