本文整理了Java中java.util.ListIterator.set()方法的一些代码示例，展示了ListIterator.set()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。ListIterator.set()方法的具体详情如下：
包路径：java.util.ListIterator
类名称：ListIterator
方法名：set

ListIterator.set介绍

[英]Replaces the last element returned by #next or #previous with the specified element (optional operation). This call can be made only if neither #remove nor #add have been called after the last call to next or previous.
[中]将#next或#previous返回的最后一个元素替换为指定的元素（可选操作）。只有在上次调用“下一个”或“上一个”后未调用“删除”或“添加”时，才能进行此调用。

public static <E> void fill(List<E> list, E value)

  if (list == null) return;
  ListIterator<E> listIterator = list.listIterator();
  while (listIterator.hasNext()) listIterator.set(value);
}

   i.set(newEntry);
   return;
  }
 }
 throw new IllegalArgumentException(
   Platform.format("key %s not found in entries %s", newEntry.getKey(), expected));
