- You have a card on which the letter J is written on one side and K on the other. You want to see all of the possible ways the card will land if you drop it n times. Write a recursive method that prints each session of dropping the cardswith J's and K's in java?Write up Java source codes for compiling and execution of program below. Draw UML diagram for codes. There is a very simple solution to keeping Tic-tac-toe fresh and interesting, though, and it has been thought up by a group of mathematicians. It’s being called Ultimate Tic-tac-toe and simply embeds a Tic-tac-toe board in each of the nine squares of the original game. Now instead of just winning the main board, you also need to win each of the smaller boards first until you have a line of three. New Rule: You can only place a mark on the board determined by the position of your opponent’s last placed mark. So, if they put an X or O in the top right corner of a square, your next move must occur in the top right board. By adding that rule the game is no longer about winning a single board, it’s about tactically managing up to 9 games at once and plotting ahead. You still win by marking three squares in a row, but that now involves winning three games. The effects of the New Rule: 1:…Is there a way to create a java program on Branching and selecting method on problems like this? Suppose that we are working for an online service that provides a bulletin board for its users. We would like to give our users the option of filtering out profanity. Suppose that we consider the words cat dog and rabbit to be profane. Write a program that reads a string from the keyboard and test whether the string contain any one of these words. Your program should find words like cAt that differ only in case. Have your program reject only lines that contain one or more of the three words exactly. For example, concatenation is a small category should not be considered profane. This problem can be solved easily. If you add a space to the beginning of the string and a space at the end of the string you only need to check if space cat space or space dog space or space rabbit space is in the string. Use three if statements; one for each word. If one or more of the words are there set…
- how to answer the follow question in java In between is a well-known card game. Many variations exist- we define it as follows. One deck of card is used. A game consist of one or more hands. A player starts with a certain number of chips called the stake (say 100) and must risk one or more chips on each hand, before seeing any cards, as long as the player still has chips and there are three or more card left in the desk(enough to play one hand), the game continues. For each hand player must risk the player For each hand the player must risk between one and their total number of chips. Two cards are dealt face up. Then the third card is dealt. If the third card is in between the first two cards, based on ranks of the cards, the player’s chips are increase by the amount risked. Otherwise they decreased by the amount. A implement the game. The application user is the player (GUI not require) (only three cards is required to play). If the first two cards are the same rank, that hand is…Write an application that prints the following diamond shape.

Define a class Car as follows: class Car { public String make; public String model; public int mpg; // Miles per gallon } a) Implement a comparator called CompareCarsByMakeThenModel that can be passed as an argument to the quicksort method from the lecture notes. CompareCarsByMakeThenModel should return a value that will cause quicksort to sort an array of cars in ascending order (from smallest to largest) by make and, when two cars have the same make, in ascending order by model. b) Implement a comparator called CompareCarsByDescendingMPG that can be passed as an argument to the quicksort method from the lecture notes. CompareCarsByDescendingMPG should return a value that will cause quicksort to sort an array of cars in descending order (from largest to smallest) by mpg. c) Implement a comparator called…

Each part is first painted in one of two colors: red or green, your information is given with string C. The color of the I-th part Ci will be equal to 'R' if the color of the part is red and 'G' if it is green. John decided to paint the whole fence green. To make the normal drawing process more fun he decided to do it using the following process. Every minute (until the whole fence is painted green) you will do the following steps: Select any part of the phone that is painted red. Let's show the index of this section as X. In each section with references X, X + 1, ..., min (N, X + K - 1), flip the color of the corresponding part from red to green and from green to red by re-painting. John wonders how quickly he can paint the phone. Please help her find the minimum number of minutes needed to repaint. Input: 1 73 RGGRGRG Output: 4
