floor in treeset java code example

Example 1: TreeSet floor() method in java

import java.util.TreeSet;
public class TreeSetFloorMethodExample
{
   public static void main(String[] args)
   {
      try
      {
         TreeSet<Integer> ts = new TreeSet<Integer>();
         ts.add(50);
         ts.add(60);
         ts.add(70);
         ts.add(80);
         System.out.println("Given TreeSet: " + ts);
         // get floor value for 65 using floor() method
         int value = ts.floor(65);
         // print floor value
         System.out.println("Floor value for 65 is : " + value);
      }
      catch(NullPointerException ex)
      {
         System.out.println("Exception: " + ex);
      }
   }
}

Example 2: TreeSet floor() method in java

floor() method for NullPointerException.
import java.util.TreeSet;
public class TreeSetFloorMethodExample
{
   public static void main(String[] args)
   {
      try
      {
         TreeSet<Integer> ts = new TreeSet<Integer>();
         ts.add(50);
         ts.add(60);
         ts.add(70);
         ts.add(80);
         System.out.println("Given TreeSet: " + ts);
         // get floor value for null using floor() method
         System.out.println("Get floor value for null: ");
         int value = ts.floor(null);
         // print floor value
         System.out.println("Floor value for 65: " + value);
      }
      catch(NullPointerException ex)
      {
         System.out.println("Exception: " + ex);
      }
   }
