Add a compareTo method to your FeetInches class, and anything else necessary but do NOT alter the toString method.

import java.util.Scanner; public class Lab7Num3 { public static class FeetInches { private int feet; private int inches; public FeetInches() { feet = 0; inches = 0; } public FeetInches(int f, int i) { feet = f + i/12; inches = i%12; } public void setFeet(int f){ feet = f; } public void setInches(int i){ feet = feet + i/12; inches = i%12; } public int getFeet(){ return feet; } public int getInches(){ return inches; } public String toString() { return " Feet: " + feet + " Inches: " + inches ; } public int compareTo(FeetInches f) { } } public static void main(String[] args) { Scanner keyboard = new Scanner(System.in); //declare an ArrayList //input the number of objects int howMany = keyboard.nextInt(); //loop howMany times, //each time input feet and inches, create a FeetInches object, add it to the ArrayList //sort the ArrayList //output the ArrayList } }
