Get ceiling key from NavigableMap in Java
Getting ceiling key means to return the least key greater than or equal to the given key. For this, use the ceilingKey() method.
The following is an example to get ceiling key from NavigableMap.
Example
import java.util.*;
public class Demo {
public static void main(String[] args) {
NavigableMap<Integer, String> n = new TreeMap<Integer, String>();
n.put(5, "Tom");
n.put(9, "John");
n.put(14, "Jamie");
n.put(1, "Tim");
n.put(4, "Jackie");
n.put(15, "Kurt");
n.put(30, "Tiger");
n.put(24, "Jacob");
System.out.println("NavigableMap elements...
"+n);
System.out.println("Ceiling Key = "+n.ceilingKey(20));
}
}Output
NavigableMap elements...
{1=Tim, 4=Jackie, 5=Tom, 9=John, 14=Jamie, 15=Kurt, 24=Jacob, 30=Tiger}
