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
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
