# Java Examples - Collection Comparison

## Problem Description:

How to compare elements in a collection ?

## Solution:

Following example compares the element of a collection by converting a string into a treeset using Collection.min() and Collection.max() methods of Collection class.

    import java.util.Collections;
    import java.util.Set;
    import java.util.TreeSet;

    class MainClass {
       public static void main(String[] args) {
          String[] coins = { "Penny", "nickel", "dime",
          "Quarter", "dollar" };
          Set set = new TreeSet();
          for (int i = 0; i < coins.length; i++)
             set.add(coins[i]);
          System.out.println(Collections.min(set));
          System.out.println(Collections.min(set,
          String.CASE_INSENSITIVE_ORDER));
          for(int i=0;i< =10;i++)
             System.out.print(-);
          System.out.println(Collections.max(set));
          System.out.println(Collections.max(set,
          String.CASE_INSENSITIVE_ORDER));
       }
    }

## Result:

The above code sample will produce the following result.

    Penny
