Java中的NavigableMap lowerEntry()方法
lowerEntry()NavigabelMap中的方法返回与最大键严格小于给定键的键-值映射关系。
以下是实现lowerEntry()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("Lower Entry is "+n.lowerEntry(10));
}
}输出结果
输出如下
NavigableMap elements...
{1=Tim, 4=Jackie, 5=Tom, 9=John, 14=Jamie, 15=Kurt, 19=Tiger, 24=Jacob}
Lower Entry is 9=John
