Write a class encapsulating the concept of an electronic device, assuming the electronic device class has the following attributes: the device description, the power (P) and the ohms (R). Include a default constructor, an overloaded constructor, accessors, mutators and the methods toString() and equals(). Also include a method returning the volts (E). Use the following Ohms Law formula to determine the volts (E):

E = PR

(E is the square root of power (P) times ohms (R) )

In addition, have your toString() method call your method that returns the volts (E) so your toString() method returns a String in the following format: (if the values of the instance variables were the following: device description: speaker, power (P): 150, Ohms (R): 8 the String returned would be:)

The speaker has the power of 150 watts, 8 ohms and is 34.64 volts. (volts (E) should be formatted to 2 decimal places)
