Can you help with the code and explanation comments? You should design a Skyscraper class, with private variables representing the state (i.e., theboard configuration) as well as the following methods:1. public boolean verifyPlacement() – this method should return true if the place-ment is valid (i.e., every row and every column contains each number exactly once.).Otherwise, this method should return false.2. public void loadPuzzle()in the format specified below. This method must update the relevant instance variablesfor the object.3. public void print()lowing the format specified below.4. public void printWithVisibility()with the visibility scores on the outside.5. A very simple main method which loads the puzzle from the user, then checks validityand prints the result. If it's valid, it also prints the puzzle with visibility.this method should read a puzzle from standard inputthis method should print the puzzle to standard output fol-this method should print the puzzle along 2.1Input and Output FormatThe loadPuzzle() method reads the configuration from standard input. This is the formatof the input and the required output for basic printing:1. The first line contains the square dimension of the board, DIM, as a single integer.2. The remaining DIM lines will each contain exactly DIM positive integers, separated bya single space, but with no trailing space after the last integer. These lines representthe heights of the skyscrapers in the same layout as the puzzle.3. All subsequent lines should be ignored.For example, the puzzle in Figure 3 is described by the input:44 3 2 11 4 3 23 2 1 42 1 4 32.1.1 printWithVisibility FormatThe printWithVisibility method should output a graphical representation of the puzzle,along with the visibility scores calculated according to the rules described earlier.For the puzzle in Figure 3, the output of this method should be:1 2 3 3114 3 2 1|42|1 4 3 2|3213 2 1 4|12|2 1 4 3|23 3 1 22.2 Design and DocumentationYou are required to have exactly the public methods described in this document. You arealso encouraged (but not required) to have helper methods. (These may be particularlyhelpful when verifying the puzzle and when calculating visibility.) All your helper methodsshould be declared private. If you have any class variables, they must be declared privateas well.Because it complicates grading, you are not allowed to have any package declarations. In-cluding package declarations in your submission will cause you to lose points.As with all Java programs, your program filename must match the public class exactly,therefore your program must be named Skyscraper.java and your class name must benamed Skyscraper.

Actually, java is a object oriented programming language. It is a platform independent.

Develop a menu-based shape-maker, using randomly generated sizes & characters: pyramid, inverted pyramid, diamond, and hourglass. Use functions to perform tasks, including separate functions for generating a random integer in a range and for generating a random character in a range. The four different shapes are made from a randomly generated printable character and a randomly generated maximum width between 4 and 12. Beneath the shape, print a descriptive caption stating the symbol and the maximum width.

simply fill in the blanks. To make it easier for you to enter the number, you may simply enter the number without having to indicate the base using the subscript. For example, you may enter AF instead of AFsixteen: Fill in the blanks. Provide the number immediately before and after the given number in the given base, respectively.

Add an event listener to the button with an id of "button2". Listen for the click event. The button should change the text content of the paragraph with an id of "p2" to: "This button toggles text content." If the button is clicked a 2nd time, the text content should change back to: "Paragraph Two."The button should switch the text back and forth, so 3rd and 4th clicks willdo the same, etc. NOTE: Questions 2 and 5 are about toggling. While Part 1 is wrong, Part 2 will be correct. This is not an error. You should try to make both parts correct.
