write a class called Temperature that has two instance varia

write a class called Temperature that has two instance variables: a temp value ( a floating - point number -data type double ) and a character for the scale , either C or F . the class should have a constructor that sets each instance variable(assume 0 degree if no temp value and c if no scale ) and it should include the following:

two accessors method: one to return the degrees Celsius and the other to return the degrees Farenheit . use formalas c= 5 (F-32)/9 and F = (9(C/5)+32

3 mutators methods; one to set vaue, one to set scale and one to set both;

a comparison method : it should return -1 if the unvoking temperature is less than the argument temperature, 0 if they are equal and 1 if invoking temperature is greater than the argument one

a toString method; return a String representing the calling Temperature object. the numeric value of the temperature should be rounded to the nearest tenth of a degree.

Then write a driver program called TempTester that tests all the methods fromt the Temperature class.

ex: 0.0 degress C = 32.0 degrees F, 100 degrees C = 212.0 degrees F.
