calculateVolumeOfCube()

Step 1:

Start by setting up the class structure for our program. We'll name our class CubeVolumeCalculator.

 public class CubeVolumeCalculator {

} 

Step 2:

Let's add a method to calculate the volume of a cube. The method will take the edge length of the cube as an input parameter. We should also add a main method to test our calculateCubeVolume function.

 public class CubeVolumeCalculator { 

   public static double calculateCubeVolume(double sideLength) { 
   //we'll implement this in step 3 
   } 

   public static void main(String[] args) {
   //we'll use this to test our function in step 4
   } 
 } 

Step 3:

In our calculateCubeVolume function, we'll use the formula for the volume of a cube, which is sideLength^3. We can achieve this in Java by using Math.pow(sideLength, 3).

 public class CubeVolumeCalculator { 

   public static double calculateCubeVolume(double sideLength) {
      return Math.pow(sideLength, 3);
   }
 } 

Step 4:

Now, in our main function we'll test our calculateCubeVolume with the edge length of 5 units.

 public class CubeVolumeCalculator { 

   public static double calculateCubeVolume(double sideLength) {
      return Math.pow(sideLength, 3);
   }

   public static void main(String[] args) {
      double volume = calculateCubeVolume(5);
      System.out.println("The volume of the cube is " + volume + " units^3");
   } 
 } 

Step 5:

At this point, we have a fully functioning CubeVolumeCalculator. When we run our main method, it calculates the volume of a cube with edge length 5 and prints The volume of the cube is 125.0 units^3. This confirms that our program is working as expected.
