Java中的NavigableMap put()方法
NavigableMapput()
方法用于在NavigableMap中设置特定的键和值。
以下是实现NavigableMapput()
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); String str = (String)n.put(20, "David"); System.out.println("Updated NavigableMap elements...\n"+n); } }
输出结果
NavigableMap elements... {1=Tim, 4=Jackie, 5=Tom, 9=John, 14=Jamie, 15=Kurt, 19=Tiger, 24=Jacob} Updated NavigableMap elements... {1=Tim, 4=Jackie, 5=Tom, 9=John, 14=Jamie, 15=Kurt, 19=Tiger, 20=David, 24=Jacob}
