Answer 1

Answer:

Here is the code, please go through the comments for better understanding of the code. Drop me a comment if you have any doubts, I'll be glad to help you. All you have to do is to create a class called Box.java, paste the below code and run, Enjoy!

public void setLength(int length) { // this method sets the length
this.length = length;
}

public void setHeight(int height) { // this method sets the height
this.height = height;
}

public void setWidth(int width) { // this method sets the width
this.width = width;
}

public void displayCalculatedVolume(){ // this method calculates the volume
volume = length*width*height;
System.out.println("The volume of the box : " + volume); // displaying the volume
}
public static void main(String [] args){ // start of main()
Box b = new Box(); // create an instance of class Box
b.setLength(10); // call the method setLength() with some int value
b.setHeight(8); // call the method setHeight() with some int value
b.setWidth(5); // call the method setWidth() with some int value
b.displayCalculatedVolume(); // calculates the volume with the given values
} // end of main()
} // end of class
