Below program illustrate the Java.util.TreeSet.remove() method:
// Java code to illustrate remove() import java.util.*; import java.util.TreeSet; public class TreeSetDemo { public static void main(String args[]) { // Creating an empty TreeSet TreeSet<String> tree = new TreeSet<String>(); // Use add() method to add elements into the Set tree.add( "Welcome" ); tree.add( "To" ); tree.add( "Geeks" ); tree.add( "4" ); tree.add( "Geeks" ); tree.add( "TreeSet" ); // Displaying the TreeSet System.out.println( "TreeSet: " + tree); // Removing elements using remove() method tree.remove( "Geeks" ); tree.remove( "4" ); tree.remove( "TreeSet" ); // Displaying the TreeSet after removal System.out.println( "New TreeSet: " + tree); } } |
TreeSet: [4, Geeks, To, TreeSet, Welcome] New TreeSet: [To, Welcome]
