Summary of Interfaces https://docs.oracle.com/javase/tutorial/java/IandI/summary-interface.htmlInstructions:
- The program creates a representation for rational numbers as fractions of int-s having the format: n/d where n and d are of type int and d is not zero.
- An interface named rational number having the following methods:
  - get numerator - no parameters, return n
  - get denominator - no parameters, return d
  - get value - compute the value as a double (n/d)
  - add - another rational - returns a rational
  - add - a double - retturns a double
  - subtract - two forms as add above
  - multiply - two forms as above
  - divide - two forms as above
  - simplify - returns another rational, equal with the original, but with n and d simplified and d>0
  - opposite - returns the opposite number
  - reciprocal - return the reciprocal number
- Add a new class RationalAsFraction implementing the above interface
  - stores two fields: n and d
  - has a static method to compute the greatest common divisor (gcd)
- Add a test class TestRational
  - Define the rationals r1..r4 and initialize them with 1/2, -3/9, 10/12 and 1
  - Compute sum=r1+r2 and diff=r4-r3
  - Simplify both results
  - Check if they are equal, using equals and comparing their numerators and denominators. What do you observe?
