Hello Java Programmers

After running the code below, i got no output for the program[img][/img]:

class Box {

double width;
double height;
double depth;
Box() {
}
Box(double w, double h, double d) {
width = w;
height = h;
depth = d;
}
void getVolume() {
System.out.println("Volume is : " + width * height * depth);
}
}

public class MatchBox extends Box {

double weight;
MatchBox() {
}
MatchBox(double w, double h, double d, double m) {
super(w, h, d);
weight = m;
}
public static void main(String args[]) {
MatchBox mb1 = new MatchBox(10, 10, 10, 10);
mb1.getVolume();
System.out.println("width of MatchBox 1 is " + mb1.width);
System.out.println("height of MatchBox 1 is " + mb1.height);
System.out.println("depth of MatchBox 1 is " + mb1.depth);
System.out.println("weight of MatchBox 1 is " + mb1.weight);
}
}

There is nothing wrong with the code

Code works. You are probably getting the packaging wrong. Make sure they are in the same package.

i tried compiling again and am told cannot find mainclass. Can i see d screen capture of the Box.java file and did u make anyone main class?

As others mentioned - your code looks fine. Make sure Box and MatchBox are in the same package. You may want to declare Box as "public", otherwise it will be put in the default package. Good luck!
