public class Box {
    //长、宽、高、容积、使用容积
    private double length;
    private double wide;
    private double height;
    private double volume;
    private double useVolume;
    public Box(double length, double wide, double height) {
        this.length = length;
        this.wide = wide;
        this.height = height;
    }
   public void getVolume(){
        volume=length*wide*height;
    }
    public void changeVo(double volume){
        useVolume=useVolume+volume;
    }
    public void emptyVo(){
        useVolume=0;
    }
    public boolean isFullVo(){
        if (useVolume==volume){
            return true;
        }
        return false;
    }
}
