TreeMap.higherEntry(K key) has the following syntax.
public Map.Entry <K , V> higherEntry(K key)
In the following code shows how to use TreeMap.higherEntry(K key) method.
/*from w ww .jav a 2 s . co m*/ import java.util.TreeMap; 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 java2s.com"); // getting higher entry for key 4 System.out.println("Checking values of the map"); System.out.println("Value is: "+ treemap.higherEntry(4)); } }
The code above generates the following result.
