Gradient FillIn this labwork are asked to write a GUI application again using AWT. This is a fairly easy labworkthat is more about getting used to synchronized online learning. You are expected to:• Draw two rectangles.• Both of them should be filled using GradientPaint() function of AWT. (Check out itsfunction definition that is listed below.)• The first gradient should be parallel to the diagonal of the first rectangle. The colorgradient should not be repeated (acyclic).• The second gradient should be horizontal. The color gradient should be repeated forthis one (cyclic).• You are free to choose the colors but other than that your output should be similar tothe example screenshot given below.
Picture card: Create a picture card that looks SIMILAR to this. There are images available in the "images" directory to assist you in making this card. They are not the same images, but there is an image of a desert and a person.
Picture card
In this screenshot, the title is "Title goes here", the secondary text is "Secondary text", and the body text is "Greyhound divisively hello coldly wonderfully marginally far upon excluding."
The card's root element is a with a class of "card".
The card is 344px wide.
The desert picture is 194px tall.
The padding between the body text and everything else is 16px.
The color of the title text is #000.
The color of the secondary and body texts is #232F34.
The size of the person picture is 40px in diameter.
The size of the body text is 11px.
The size of the title is 22px.
For the padding or margin around any other elements, use your best judgment to make it look like the screenshot.
You have some questionable legacy code (that doesn't use interfaces) that you want
to enhance, but you don't want to risk breaking other code that uses it. Which
pattern would you use?

You can read the rules in it's entirety of the Hunt the Wumpus game online to get a better idea of the specifications. It's an actual game. INFORMATION: The object of this game is to find and kill the Wumpus within a minimum number of moves, before you get exhausted or run out of arrows. There is only one way to win: you must discover which room the Wumpus is hiding in and kill it by shooting an arrow into that room from an adjacent room. The Cave The Wumpus lives in a cave of 30 rooms. The rooms are hexagonal. Each room has up to 3 tunnels, allowing access to 1, 2 or 3 (out of 6) adjacent rooms. The attached diagram shows the layout of rooms in the cave. The map wraps around such that rooms on the edges (white cells) have neighbors from the opposite edge (blue cells). E.g., the neighbors of room 1 are rooms 25, 26, 2, 7, 6, and 30, and you could choose to connect room 1 to any of these rooms.

Each player will take turns attempting to add letters to a growing word fragment. The letter you select should attempt to force your opponent to spell a word or create a word fragment that has no possibility of creating a word. Unlike the prior ghost competition, when it is your turn you are allowed to add a letter to either the front or back of the word fragment. Winning Criteria: If your opponent spells a word that is at least 6 characters long if your opponent creates a word fragment that has no possibility of creating a word if your opponent takes longer than 60 seconds to select a word. Tip: If you are the first player you can only spell words that are odd length thus you can only lose when you spell words that are odd but you can win when your opponent spells words that are…arrow_forward
- In a bounding box with scaling handles, what happens if you hover your mouse cursor over one of the handles on the edge or corner of the box?arrow_forwardYou are creating a simple RPG video game, and you need to work out some details for your crafting menu. Your characters can craft two potions with simple ingredients: Minor Mana, and Minor Healing. The two potions have similar ingredients with some slight differences shown below. You want to add a "Craft All Potions" option, which will ask the user if they would like to prioritize Healing or Mana potions. It will then tell you how many you can produce of your priority potion, and then with the leftovers it will craft the other type of potion if it is possible. First ask for the priority potion, and then the quantities of the ingredients as an input. Then output how many of the priority potion you can make, and how many of the other potion. If the user provides an invalid input, ask them again.arrow_forwardOpen the clock-display project and create a ClockDisplay object by selecting the following constructor: new ClockDisplay() Call its getTime method to find out the initial time the clock has been set to.

- Prompt: Create a virtual pet care game where players can choose a cute pet and then feed, train, or play-with it. The game is based on a simple game loop, where at the beginning of each loop, the game notifies the player of the current pet status (hungry, sleepy, bored, etc.) The player should then select the corresponding actions to improve the status of the pet. After each action, the game loop is repeated and the pet values are updated. The status should be displayed along with the corresponding messages as well as the menu of actions. Design Requirements: Implement the Pet class Create the base Pet class. It should manage variables that keep track of the pet's state, such as how hungry/sleepy/bored/happy the pet is currently. Include a function that updates the pet's state values to reflect the passage of time. If any of the variables are above some threshold (such as 40 out of 100), the function should output the corresponding message such as "<Pet name> is hungry!"

Test each potential move to see if the knight has already visited that square. Test every potential move to ensure that the knight does not land off the chessboard.
