Oh dear! I shall be late!” (when she thought it over afterwards, it occurred to her that she ought to have wondered at this, but at the time it all seemed quite natural); but when the Rabbit actually took a watch out of its waistcoat-pocket, and looked at it, and then hurried on, Alice started to her feet, for it flashed across her mind that she had never before seen a rabbit with either a waistcoat-pocket, or a watch to take out of it, and burning with curiosity, she ran across the field after it, and fortunately was just in time to see it pop down a large rabbit-hole under the hedge."

This constructor should invoke the 4-argument constructor using the this keyword. • Your program must have these methods: 。 Getter methods for all fields (e.g. getColour () which returns the colour) о о getVolume: returns the cuboid volume which is 1*w*h getSurfaceArea(): returns the surface area of the cuboid: (2*(1*w + 1*h + w*h) displayInfo(): displays on the screen the colour, dimensions, surface area, and volume of this cuboid.
