import java.util.ArrayList;
import java.util.Collections;
// Declare method TimeSpanDemo
public class TimeSpanDemo
{
public static void main(String[] args)
{
//Declare variables
TimeSpan ts1 = new TimeSpan(3, 15);
TimeSpan ts2 = new TimeSpan(1, 40);
TimeSpan ts3 = new TimeSpan(4, 10);
TimeSpan ts4 = new TimeSpan(2, 50);
//Declare variable timespans
ArrayList timeSpans = new ArrayList();
timeSpans.add(ts1);
timeSpans.add(ts2);
timeSpans.add(ts3);
timeSpans.add(ts4);
//Print the statement
System.out.println("Time spans in the list before sorting: " + timeSpans);
Collections.sort(timeSpans);
//Print the statement
System.out.println("Time spans in the list after sorting: " + timeSpans);
}
}
