4.2.3: Method definition: Volume of a pyramid. Define a method pyramidVolume with double parameters baseLength, baseWidth, and pyramidHeight, that returns as a double the volume of a pyramid with a rectangular base. Relevant geometry equations: Volume = base area x height x 1/3Base area = base length x base width.(Watch out for integer division). import java.util.Scanner; public class CalcPyramidVolume { //answer goes here// public static void main (String [] args) { Scanner scnr = new Scanner(System.in); double userLength; double userWidth; double userHeight; userLength = scnr.nextDouble(); userWidth = scnr.nextDouble(); userHeight = scnr.nextDouble(); System.out.println("Volume: " + pyramidVolume(userLength, userWidth, userHeight)); }}
You can just provide code as you don't have required utility class, Please provide explanation and comments for code : Write a static method asciiGraph(), to display a “graph” of ASCII values of a String. 2.The method has a single String parameter str, and returns nothing (void).3.The method loops through all characters in str, and for each displays a line of *s on a row equal to the ASCII/Unicode integer value of the character being examined (see example).Hints:1. recall the String methods .charAt() and .length(), and casting a char with (int) directly returns the int ASCII/Unicode value2. to produce the line of *s, call the method starLine() from the Exam utility class3. in the output capture document, consider reducing the font size to 7 or 8 point to have each row of *s on a single line Consider the strings “Ab C” and “TED 99”, that are composed of:A displays 65 stars (*), since Unicode 65 = 'A'b 98 stars (*), since Unicode 98 = 'b'space 32 * , since Unicode 32 = ' ' (the space)C…
The Java code provides a Class named Function in Function.java that has a static method named f that takes a double argument and returns the value of . It also has a static method named fprime that takes a double argument for x and returns the value of the slope of f(x). The slope of f(x) can be calculated as . Implement this method. public class Function { public static double f(double x) { return Math.pow(x,3) - 3 * x; } public static double fprime(double x) { // your code goes here } }

python pleaseWrite a class called Point that represents a point in 2D plane.- The constructor accepts the x and y dimensions of the point.- Provide a method getX that returns the x coordinate of a point, and another method getYthat returns the y coordinate of a point.- Provide a method called translate that changes the original coordinates of the point byadding a given values for x and y coordinates.- Provide a method distanceTo that calculates the distance between that point and anotherone.Use this equation to calculate the Distance math.sqrt((x2 - x1) ** 2 + (y2 - y1) ** 2))While the math is a library you should import. Where the (x1, y) is the coordinates of the first pointand (x2, y2) is the coordinates of the second pointThe output should be like this screenshot.
Define a Static method 'max' with return type as 'int' in class 'ProblemSolution' that take two numbers with type 'int'. Inside the 'max' method, compare the two numbers and return the maximum of the two numbers. Then, inside the 'main' method. Define two 'int' type numbers; the first number (num1) is equal to 5 and the second number (num2) is equal to 2. At the next line, call the 'max' method where its parameter input are the two numbers above, and assign the result of the method to the variable num3 (type 'int'). Finally, on the next line, print out -> "The maximum of " + num1 + " and " + num2 + " is " + num3 Output The maximum of 5 and 2 is 5 Where, There must be space between all the words and numbers. There should not any space after the last number
Basic Java please Write a method called torusVolume(? littleR, ? bigR) that takes an int littleR and an int bigR in as parameters. Use the two values to find and return the volume as a double of the associated regular octagonal prism. The formula for the volume of a torus is (2πR)⋅(πr^2)
For this problem you will write a method that computes the number of boxes in a pyramid of boxes based on the number of boxes in the base. The boxes in each layer of the pyramid are stacked directly on top of one another (i.e. not offset between two boxes below). For example, below are shown two pyramids, one with base 5 and one with base 6. [] [][] [][][] [][][][] [][][][][] [][][][][][] Implement and test the computePyramidBoxes() method in the PyramidBoxCount class. When testing the computePyramidBoxes() method you should be sure to have at least one test method for each base case and at least one test method for each recursive case in your program.
