Java中的NavigableMap floorEntry()方法
floorEntry()的NavigableMap方法返回与最大键关联的键-值映射小于或等于给定键
以下是实现floorEntry()方法的示例-
示例
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(19, "Tiger");
n.put(24, "Jacob");
System.out.println("NavigableMap elements...\n"+n);
System.out.println("\nFloor Entry = "+n.floorEntry(5));
}
}输出结果
NavigableMap elements...
{1=Tim, 4=Jackie, 5=Tom, 9=John, 14=Jamie, 15=Kurt, 19=Tiger, 24=Jacob}
Floor Entry 5=Tom
