本文整理了Java中java.util.AbstractMap.entrySet()方法的一些代码示例，展示了AbstractMap.entrySet()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。AbstractMap.entrySet()方法的具体详情如下：
包路径：java.util.AbstractMap
类名称：AbstractMap
方法名：entrySet

AbstractMap.entrySet介绍

[英]Returns a set view of the mappings contained in this map. Each element in this set is a Map.Entry. The set is backed by the map, so changes to the map are reflected in the set, and vice-versa. (If the map is modified while an iteration over the set is in progress, the results of the iteration are undefined.) The set supports element removal, which removes the corresponding entry from the map, via the Iterator.remove, Set.remove, removeAll, retainAll and clear operations. It does not support the add or addAll operations.
[中]返回此映射中包含的映射的集合视图。此集合中的每个元素都是一个映射。进入集合由映射支持，因此对映射的更改将反映在集合中，反之亦然。（如果在对集合进行迭代时修改贴图，则迭代的结果未定义。）该集合支持元素删除，即通过迭代器从映射中删除相应的条目。移除，设置。移除、移除所有、保留和清除操作。它不支持添加或添加所有操作。
