Given the following CircleDriver.java file. Provide an accompanying Circle.javafile. Specifically, your Circle class should contain:• One instance variable – radius• A method named setRadius that assigns the passed-in radius value to the radiusinstance variable.• A method named initialize that prompts the user for a radius value and thenassigns the entered value to the radius instance variable.• A method named printCircleData that uses the circle’s radius to calculate thecircle’s diameter, circumference, and area. Use the Java API constant Math.PIfor the value of π. Print the circle’s radius, diameter, circumference, and area. Thereare many ways to implement printCircleData. In the interest of gainingexperience with local variables, declare and use local variables for storing thecircle’s diameter, circumference, and area.

Hello, i need help with this question
There are 12 inches in a foot and 3 feet in a yard. Create a class named InchConversion. Its main() method accepts a value in inches from a user at the keyboard, and in turn passes the entered value to two methods. One converts the value from inches to feet, and the other converts the same value from inches to yards. Each method displays the results with appropriate explanation. Save the application as InchConversion.java.

The Math class contains a static method named Sqrt() that accepts a double and returns the parameter’s square root. If the user’s entry cannot be converted to a double, display an appropriate message, and set the square root value to 0. Otherwise, test the input number’s value. If it is negative, throw a new ApplicationException to which you pass the message “Number can’t be negative.” and again set sqrt to 0.
