• must require .extra instance variable• calculated volume again inside method getSnowVolume()• calculated snow volume again inside method getSnowCost() Remember to follow our Programming Style Requirements!Problem AYou have all probably seen a snow globe - a glass ball containing a winter scene and filled with aliquid, and white particles. When turned upside down, the white particles float to the bottom.When turned right-side up again, the particles drift down looking like snow.MacBook AirDII00F4F5F6F7F8*$&4579< cO Write a class SnowGlobe to model this behavior according to the following description.20% of the volume of the object will be filled with white particles while 50% will be filled witha liquid. The other 30% is the things in the scene. The snow costs $1.25 per cubic centimeter.You must use the following static constants in the class. No magic numbers!public static final double VOLUME COEFFICIENT = 4 / 3.0;public static final double COST PER CUBIC CENTIMETER = 1.25;public static final double SNOW PERCENTAGE = 0.2;Provide two constructors. Both constructors have the same name, SnowGlobe. The compilertells them apart becausehey have different parameter lists. This is called overloading.A no-argument constructor (also called a default constructor) that sets the radius to 10.0centimeters.A constructor that accepts a double as the radius in centimeters as an argument.The class has the following methods:setRadius () Sets a new radius.getRadius () Gets the radiusgetVolume () Gets the volume of the sphere in cubic centimetergetSnowVolume () Gets the volume of the snow in cubic centimeter. Do notcalculate the volume of sphere in this method. Call the getVolume () method so youonly calculate the volume in one method.getSnowCost () Gets the cost of the snow needed in this globe. Do not calculate thevolume of snow in this method. Call the getSnowVolume () method so you onlycalculate the snow volume in one method.Use the following formula to calculate the volume of a sphere with the constant from the Mathclass for t.V = (4/3) nrJavadoc comments and tags are required.

Below i have created the desired class:

The class has the following methods: setRadius () Sets a new radius. getRadius () Gets the radius getVolume () Gets the volume of the sphere in cubic centimeter getSnowVolume () Gets the volume of the snow in cubic centimeter. Do not calculate the volume of sphere in this method. Call the getVolume () method so you only calculate the volume in one method. getSnowCost () Gets the cost of the snow needed in this globe. Do not calculate the volume of snow in this method. Call the getSnowVolume () method so you only calculate the snow volume in one method.

The class has the following methods: setRadius () Sets a new radius. getRadius () Gets the radius getVolume () Gets the volume of the sphere in cubic centimeter getSnowVolume () Gets the volume of the snow in cubic centimeter. Do not calculate the volume of sphere in this method. Call the getVolume () method so you only calculate the volume in one method. getSnowCost () Gets the cost of the snow needed in this globe. Do not calculate the volume of snow in this method. Call the getSnowVolume () method so you only calculate the snow volume in one method.
