Input is from a file: The first upper case character on each line determines what type of object it is (C for Circle, R for Rectangle, F for Fraction, I for FeetInches). A C will be followed by a Double (the radius of the Circle you will create) An R will be followed by 2 Doubles, the length and width of the Rectangle you will create An F will be followed by 2 ints, the numerator and denominator An I will be followed by 2 ints, the feet and inches. After you create each object put it into an ArrayList. (There will be 4 ArrayLists, one for Circles, one for Rectangles, one for Fractions, one for FeetInches) USE A SWITCH STATEMENT to determine which constructor to call (which object to make). After you have input all your objects into the ArrayLists print them all out, First all the Circles from that ArrayList, then all the Rectangles, etc. State clearly what you are printing. e.g. These are the Circles:

This is what I have so far:
