Sortedset with Example


When you want to sort the data we have to go with sortedset by default the sorting order is ascending.
You can customize the sorting order by Implementing comparator interface.

You can use treeset for sorting and for this you need to use the constructor which accepts comparator as argument.

Example:

public class Example {


public static void main(String[] args) {


SortedSet ss=new TreeSet();

ss.add("a");
ss.add("e");
ss.add("g");
ss.add("b");
ss.add("c");

Iterator it=ss.iterator();

while(it.hasNext())
{
String value=(String)it.next();
System.out.println("Value :"+value);
}
}
}
