The following is an example to implement the lower() method in Java −

Example

 Live Demo

import java.util.NavigableSet;
import java.util.TreeSet;
public class Demo {
   public static void main(String[] args) {
      NavigableSet<Integer> set = new TreeSet<>();
      set.add(10);
      set.add(25);
      set.add(40);
      set.add(55);
      set.add(70);
      set.add(85);
      set.add(100);
      System.out.println("Returned Value = " + set.lower(35));
   }
}

Output

Returned Value = 25
