包路径：java.util.AbstractMap
类名称：AbstractMap
方法名：toString

AbstractMap.toString介绍

[英]This implementation composes a string by iterating its entry set. If this map contains itself as a key or a value, the string "(this Map)" will appear in its place.
[中]此实现通过迭代其条目集来组成字符串。如果此映射包含自身作为键或值，则字符串“（此映射）”将显示在其位置。
