NavigableSet lower() method in Java

Last Updated : 11 Jul, 2025

The lower() method of

is used to return the greatest element in this set strictly less than the given element, or null if there is no such element exists in the set.

:

E lower(E ele)

Where, E is the type of elements maintained by this Set container.

: This function accepts a parameter

which refers to type of element maintained by this Set container.

: It returns the greatest element in this set strictly less than the given element, or null if there is no such element. Below programs illustrate the lower() method in Java:

: NavigableSet with integer elements.

// A Java program to demonstrate lower()
// method of NavigableSet
import java.util.NavigableSet;
import java.util.TreeSet;

public class GFG {
    public static void main(String[] args)
    {
        NavigableSet<Integer> ns = new TreeSet<>();
        ns.add(0);
        ns.add(1);
        ns.add(2);
        ns.add(3);
        ns.add(4);
        ns.add(5);
        ns.add(6);

        System.out.println("Greatest element strictly less than"
                           + " 4 is: " + ns.lower(4));
    }
}

Greatest element strictly less than 4 is: 3

NavigableSet with string elements.

// A Java program to lower()
// method of NavigableSet
import java.util.NavigableSet;
import java.util.TreeSet;

public class GFG {
    public static void main(String[] args)
    {
        NavigableSet<String> ns = new TreeSet<>();
        ns.add("A");
        ns.add("B");
        ns.add("C");
        ns.add("D");
        ns.add("E");
        ns.add("F");
        ns.add("G");

        System.out.println("Greatest element strictly less than"
                           + " D is: " + ns.lower("D"));
    }
}

Greatest element strictly less than D is: C
