Java提供了一组可以以键值对(key-value)的形式存储数据的数据结构,这种结构称之为Map。可以Map看成一个多行两列的表格,其中第一列存储key,第二列存储value,而每一行就相当于一组key-value对,表示一组数据结构。 Map对存入的元素只有一个要求,就是key不能重复,所谓的不能重复指的是Map中不能包含两个equals为t...
另一方面,Collection 或 Set 对象的 toArray() 方法却创建包含 Map 所有元素的数组对象,因此除了确实需要使用数组中元素的情形外,其效率并不高。 我运行了一个小测试(随附文件中的 Test1),该测试使用了 HashMap,并使用以下两种方法对迭代 Map 元素的开销进行了比较: int mapsize = aMap.size();Iterator keyVa...
