Write static methods: • public static double cubeVolume(double h) : h! • public static double cubeSurface(double h) : 6h" • public static double cylinderVolume(double r, double h) : h??" • public static double cylinderSurface(double r, double h) : 2??h + 2??" that compute the volume and surface area of a cube with height h, and a cylinder with circular base with radius r and height h. Place them into a class named “Geometry.java”. Then write a program with main class called here.java” that prompts the user for the values of r and h, calls the four methods, and prints the results. B.ReconsideryourprevioussolutionbyimplementingclassesCube,and Cylinder separately instead of a single class “Geometry” (part A). Which approach is more object-oriented?

The weight of an object can be described by two integers: pounds and ounces (where 16 ounces equals one pound). Class model is as follows: public class Weight { private int pounds; private int ounces; public Weight(int p, int o) ( pounds=p+o/16: ounces = 0% 16: } Implement a method called subtract, which subtracts one weight to another. i.e. Weight w1 = new Weight(10.5): Weight w2 = new Weight(5.7): Weight w3= w1.subtract(w2):

Write a program called AveMethod (main method) that contains a method called threeAve (method name) that computes the average of three numbers.  a) The main method will do the following: • asks the user for 3 number (double type). • calls the threeAve method• print the average of the three numbersb) The threeAve method will do the following: • receives 3 numbers (parameters)• calculate the average of the three numbers• returns the average Sample Run: Input the first number: 2.5Input the second number: 3.5Input the third number: 6.6The average is 4.2

a Java program that defines and uses 3 overloaded methods (the Java file nameshould be “MethodOverload.java” and all the 3 methods should have the same methodname max). The 3 method headers are given below with their definitions:• int max(int n1, int n2, int n3):o to return the maximum of the passed 3 integer arguments.• double max(double d1, double d2, double d3):o to return the maximum of the passed 3 double arguments with use ofMath.max() method—that is, do not use if or if-else statement incomparing the numbers to find the smaller/smallest numbers.• int max(int n):In the main method of the application, a loop with switch-statement inside is required fortesting the different method calls and you need to generate random numbers for the inputsas the arguments for the methods (except for die-rolling case where an input is enteredfrom the keyboard.). Specifically:• int max(int n1, int n2, int n3): the 3 random integers should be from the sequence2, 5, 8, 11, 14.• double max(double d1,…
