下面的例子来解释Map的功能

import java.util.*; public class CollectionsDemo { public static void main(String[] args) { Map m1 = new HashMap(); m1.put("Zara", "8"); m1.put("Mahnaz", "31"); m1.put("Ayan", "12"); m1.put("Daisy", "14"); System.out.println(); System.out.println(" Map Elements"); System.out.print("t" + m1); } }

以上实例编译运行结果如下：

Map Elements {Mahnaz=31, Ayan=12, Daisy=14, Zara=8}
