+getVolume(): int
+getSurfaceArea(): int

+--------------------------------+

A class Package (like a box) is designed as shown in the UML class diagram. It contains:

Three private instance variables: length, width and height all of type int. A constructor which takes three int arguments for length, width and height. Public methods: getVolume() and getSurfaceArea(), which return the volume and surface area of this instance, respectively. Use these formulas: volume = whl (w multiplied by h multiplied by l) Surface Area = 2(wl + hl + hw) meaning 2 multiplied by the sum of wl (w multiplied by l), plus hl plus hw.

The program reads the values of l, w, and h. Creates a Package object and calls the Package methods to produce the output. Example:

Input 2 2 2

Output Package Volume is : 8 Area is: 24

Input 2 5 10

Output Package Volume is: 100 Area is: 160

class Package { private int length; private int width; private int height;

// Constructor with parameters
public Package(int l, int w, int h) {
    length = l;
    width = w;
    height = h;
}

// Method to calculate and return the volume
public int getVolume() {
    return width * height * length;
}

// Method to calculate and return the surface area
public int getSurfaceArea() {
    return 2 * (width * length + height * length + height * width);
}

}

import java.util.Scanner;

public class Main { public static void main(String[] args) { Scanner scnr = new Scanner(System.in);

    // Read input for length, width, and height
    int length = scnr.nextInt();
    int width = scnr.nextInt();
    int height = scnr.nextInt();

    // Create a Package object
    Package myPackage = new Package(length, width, height);

    // Display the package details
    System.out.println("Package");
    System.out.println("Volume is: " + myPackage.getVolume());
    System.out.println("Area is: " + myPackage.getSurfaceArea());

    scnr.close(); // Close the scanner
}
