类名称：AbstractMap
方法名：equals

AbstractMap.equals介绍

[英]This implementation first checks the structure of object. If it is not a map or of a different size, this returns false. Otherwise it iterates its own entry set, looking up each entry's key in object. If any value does not equal the other map's value for the same key, this returns false. Otherwise it returns true.
[中]此实现首先检查对象的结构。如果不是贴图或大小不同，则返回false。否则，它将迭代自己的条目集，在对象中查找每个条目的键。如果任何值不等于同一个键的其他贴图的值，则返回false。否则返回true。

public static void main(String args[]) {
HashMap<String, Object> map = new HashMap<String, Object>();
map.put("2", "whatever2");
map.put("1", "whatever1");
TreeMap<String, Object> map2 = new TreeMap<String, Object>();
map2.put("2", "whatever2");
map2.put("1", "whatever1");

System.out.println("Are maps equal (using equals):" + map.equals(map2));
System.out.println("Are maps equal (using toString().equals()):"
    + map.toString().equals(map2.toString()));

System.out.println("Map1:"+map.toString());
System.out.println("Map2:"+map2.toString());
}
