Describe in general how you’d remove any continue statement from a loop in a program and replace it with some structured equivalent. Use the technique you develop here to remove the continue statement.
What will be an ideal response?
A loop can be rewritten without a continue statement by moving all the code that appears in the body of the loop after the continue statement to an if statement that tests for the opposite of the continue condition. Thus, the code that was originally after the continue statement executes only when the if statement’s conditional ex- pression is true (i.e., the “continue” condition is false). When the “continue” condi- tion is true, the body of the if does not execute and the program “continues” to the next iteration of the loop by not executing the remaining code in the loop’s body.

Create an application that will play a simple one-player card game. In this game, you get four random cards that have values in the range from 1 to 10 and are face down so their values hidden. As the game progresses, you can press a NewCard button and get a new card with its value shown. Use an icon and a label to display the card. Getting a new card will cost you one point from your total score. You can then choose to replace one of your four cards with the new card. To do so, implement the four cards as buttons with icons and use a button press to indicate which card you want to replace. When the card is replaced, use a text label to inform the player of the value of the card that was replaced. Make sure that only one card can be replaced. At any point, you can press a Stop button to sto
This application can really look nice with appropriate use of icons. The solution has an icon for the back of the card and one for each of the faces. It then uses the setIcon method for a JButton to change the image as needed. The solution uses getSource to determine which button was pressed, but it could be easily modified to check for an action string instead. The most complicated part of the application is deciding what to do for each click as there are a number of possible states that we can be in and we want to keep track of the score as the player deals out cards. One interesting thing to do is to analyze this game. Is it advantageous to deal a card? Once the card is dealt, should we replace one of our known or unknown cards with it? This game is simple enough that it can be analyzed, but complicated enough to make it interesting.
