Question

Give an example of instance variables.

Answer 1

class Cuboid {
    private double height;
    private double width;
    private double depth;
    private double volume;

    public void input(int h, int w, int d) {
        height = h;
        width = w;
        depth = d;
    }

    public void computeVolume() {
        volume = height * width * depth;
        System.out.println("Volume = " + volume);
    }
}

Height, width, depth, and volume are instance variables.
