Code:
/* A program that uses the Box class.

Call this file BoxDemo.java

*/

class Box {

double width;

double height;

double depth;

}

// This class declares an object of type Box.

class BoxDemo {

public static void main(String args[]) {

Box mybox = new Box();

double vol;

// assign values to mybox's instance variables

mybox.width = 10;

mybox.height = 20;

mybox.depth = 15;

// compute volume of box

vol = mybox.width * mybox.height * mybox.depth;

System.out.println("Volume is " + vol);

}

}

When executed it doesn't shows up anything (running in Netbeans)
