- Write static methods: public static double cubeVolume(double h) : h^3 public static double cubeSurface(double h) : 6h^2 public static double cylinderVolume(double r, double h) : hπr^2 public static double cylinderSurface(double r, double h) : 2rπh+2πr^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 “Lab7_yourID.java” that prompts the user for the values of r and h, calls the four methods, and prints the results. (Optional) Reconsider your previous solution by implementing classes Cube, and Cylinder separately instead of a single class “Geometry” (part A). Which approach is more object-oriented?Given four overloading method definitions,(Java language) // Method 1 public static int m(int n1, int n2) { return n1+n2; } // Method 2 public static double m(double n1, double n2) { return n1+n2; } // Method 3 public static double m(double n1, int n2) { return n1+n2; } // Method 4 public static double m(int n1, int n2, double n3) { return m(n1,n2)+n3; } write which of the four methods is invoked for: int sum = m(5,8); Answer: double sum2 = m(-6.4,8); Answer: double sum3 = m(3,9,12.5); Answer: double sum4 = m(0,15.8); Answer:What is printed by the following code segment? doThus(3, 1); What is printed by the following code segment? doThus(3, 1); Given the method definitions: public static int doThat(int x, int y) { System.out.println("that " + x + " " + y); x = x + y; System.out.println("that " + x + " " + y); return x; } public static int doThus(int x, int y) { System.out.println("thus " + x + " " + y); y = doThat(y + x, x - y); System.out.println("thus " + x + " " + y); return y; } ___________ ___________ ___________ ___________
