Demonstrate various algorithms like Sort, Shuffle and reverseOrder

Here is a Java Program to Demonstrate various algorithms.

import java.util.*;

class AlgorithmsDemo {
  public static void main(String args[]) {

    // Create and initialize linked list
    LinkedList ll = new LinkedList();
    ll.add(new Integer(-8));
    ll.add(new Integer(20));
    ll.add(new Integer(-20));
    ll.add(new Integer(8));
    
    // Create a reverse order comparator
    Comparator r = Collections.reverseOrder();

    // Sort list by using the comparator
    Collections.sort(ll, r);

    // Get iterator
    Iterator li = ll.iterator();

    System.out.print("List sorted in reverse: ");    
    while(li.hasNext())
      System.out.print(li.next() + " ");
    System.out.println();

    Collections.shuffle(ll);

    // display randomized list
    li = ll.iterator();
    System.out.print("List shuffled: ");    
    while(li.hasNext())
      System.out.print(li.next() + " ");
    System.out.println();

    System.out.println("Minimum: " + Collections.min(ll));    
    System.out.println("Maximum: " + Collections.max(ll));        
  }
}

Output of Above Java Program
List sorted in reverse: 20 8 -8 -20
List shuffled: -20 20 -8 8
Minimum: -20
Maximum: 20
