Question

Given the following class with a method to get the weight, how would I write a class that can contain many of them and write a method to find the one with the largest weight?

public class Item{
    int weight;
    public int GetWeight(){
        return weight;
    }
}

public class ItemContainer{
    Item[] items;
    public Item GetMaxWeight(){
        //find Item with largest weight
    }
}

Answer 1

You could use a variable to track it as well.

YourObject maxWeight = null; // The temp to determine the max
YourObject current = new YourObject(); // The current object you're storing input into

// Get Data for current from whatever source you're using
if (maxWeight == null || current.getWeight() > maxWeight.getWeight())
    maxWeight = current;

// Do other processing and get the rest of the data
System.out.println(maxWeight.getName() + " has the maximum weight.");
