{

public static void main(String[] args)

{

TreeSet tSet = new TreeSet();

tSet.add("1");

tSet.add("3");

tSet.add("2");

tSet.add("5");

tSet.add("4");

SortedSet sortedSet = tSet.tailSet("2");

System.out.println("Tail Set Contains : " + sortedSet);

   }

}

Get lowest and highest value stored in Java Tree Set

import java.util.TreeSet;

public class GetLowestHighestValueTreeSetExample

{

public static void main(String[] args)

{

TreeSet tSet = new TreeSet();

tSet.add("1");

tSet.add("3");

tSet.add("2");

tSet.add("5");

tSet.add("4");

System.out.println("Lowest value Stored in Java TreeSet is : " + tSet.first());

System.out.println("Highest value Stored in Java TreeSet is : " + tSet.last());

   }

}

Iterate through elements of Java Tree Set

import java.util.TreeSet;

tSet.add(new Integer("1"));

tSet.add(new Integer("2"));

tSet.add(new Integer("3"));

Iterator itr = tSet.iterator();     

System.out.println("TreeSet contains : ");

while(itr.hasNext())

System.out.println(itr.next());

   }

}

Remove all elements from Java Tree Set

System.out.println("TreeSet before removal : " + tSet);

tSet.clear();

System.out.println("TreeSet after removal : " + tSet);

System.out.println("Is TreeSet empty ? " + tSet.isEmpty());    

   }

}

Remove specified element from Java Tree Set

import java.util.TreeSet;

System.out.println("TreeSet before removal : " + tSet);

boolean blnRemoved = tSet.remove(new Integer("2"));

System.out.println("Was 2 removed from TreeSet ? " + blnRemoved);     

System.out.println("TreeSet after removal : " + tSet);

   }

}
