Quelle est la différence entre Collection et Collections en Java ?

public interface Collection<E> extends Iterable<E>

public class Collections extends Object

import java.util.*;
public class CollectionTest {
   public static void main(String args[]) {
     <strong> </strong>ArrayList<Integer> list = new ArrayList<Integer>();
      // Adding elements to the ArrayList
      list.add(5);
      list.add(20);
      list.add(35);
      list.add(50);
      list.add(65);
<strong>      </strong>// Collections.min() method to display minimum value<strong>
</strong>      System.out.println("Minimum value: " + Collections.min(list));
<strong>      </strong>// Collections.max() method to display maximum value<strong>
</strong>      System.out.println("Maximum value: " + Collections.max(list));
   }
}

Minimum value: 5
Maximum value: 65
