Answer:

b. Play music

Explanation:

Digital technology helps improve an existing process and makes things better. In this scenario of an MP3 player, digital technology takes care of music. Before a portable MP3 player came into the picture, people had to carry large physical records or multiple CD packs but now, a small device can hold thousands of those same songs in it.

What is a constructor? Why would you include a constructor in a class?
QveST [7]

Answer:

Constructor in the class is the member function that gets into action when any new object gets created in the class ,it gets invoked. It does not have any return type and no void return.

The constructor is used in the class because there is the requirement for the initializing of the new object and then only object can do the functioning in the program.

Define a method calcPyramidVolume with double data type parameters baseLength, baseWidth, and pyramidHeight, that returns as a d
Rudik [331]

Answer:

import java.io.*;

public class Main {

   public static void main(String[] args) throws IOException {

       double baseLength = 0, baseWidth = 0, pyramidHeight = 0;

       Object[] volume;

       volume = calcPyramidVolume(baseLength, baseWidth, pyramidHeight);

   }

   public static Object[] calcPyramidVolume(double baseLength, double baseWidth, double pyramidHeight) {

       double area = calcBaseArea(baseLength, baseWidth);

       double volume = baseLength * baseWidth * pyramidHeight;

       return new Object[]{volume, area};

   }

   public static double calcBaseArea(double length, double width) {

       return length * width;

   }

}

Explanation:

The problem is flawed because it is completely inefficient for one to create two separate methods to calculate the volume and the area when they can be done at once.

The second problem is that it was never specified whether to return something from the calcBaseArea method.

I assumed it required it, so it is not advisable to initiate the method as a double, but rather create it as an Object so that it can return two values: the volume and the area.
