You will implement a comparable interface within Frult objects. Pretend that all fruit costs a toonie, no matter the size. To get more for your money, you will want to buy the bigger fruit. Details Input Input for this problem will be a fruit name, followed by a colour, and then the weight. Input has been handled for you in POD.java. Processing & Output Compare the weight of the object with the weight of the Frult object taken as input. The value you return from the compareTo() method will be as follows: • If the weight of the fruits is equal, you will return 0. If the current fruit object is greater, return 1. • Otherwise (i.e. the other fruit object is greater), you will return -1. This will allow us to sort the fruit objects by weight. This sort is handled in the main method of POD.java'. All output from that method is handled for you.
