Java Collection Tutorial - Java TreeMap.lowerEntry(K key)


TreeMap.lowerEntry(K key) has the following syntax.

public Map.Entry <K , V> lowerEntry(K key)


In the following code shows how to use TreeMap.lowerEntry(K key) method.

import java.util.TreeMap;
/*w  w w .jav  a2s.  co m*/
public class Main {
   public static void main(String[] args) {
      TreeMap<Integer, String>  treemap = new TreeMap<Integer, String> ();
      // populating tree map
      treemap.put(2, "two");
      treemap.put(1, "one");
      treemap.put(3, "three");
      treemap.put(6, "six");
      treemap.put(5, "from");
      // getting lower entry  
      System.out.println("Checking lower entry");
      System.out.println("Value is: "+ treemap.lowerEntry(5));

The code above generates the following result.
