Hello!

I am trying to find how many jelly beans can fit in a jar. so I made some variables.



double height, diameter, beanLength, beanDiameter, glassThickness, radius, newRadius;

double volumeOfJar, airCubicInches, trueVolume, jellyBeanVolume;



as show here. But I need to initialize them. so I tried this



int height;

int diameter;

int beanLength; beanLength = 0.625;

int beanDiameter; beanDiameter = 0.25;

int glassThickness;

int radius;

int newRadius;

int volumeOfJar;

int airCubicInches;

int trueVolume;

int jellyBeanVolume;



But my program does not like that. How do I fix the varibles to be initialized?
