如何转换清单 <object> 到字符串数组

Question

How can I convert a object list to a string array?

I tried the following code, but I get an ArrayStoreException Error

 List<Object> content = mdp.getContent(); //From docx4j API
 Object[] objectArray = content.toArray();
 String[] paragraphs = Arrays.copyOf(objectArray, objectArray.length, String[].class); 

Thanks

If you already have just strings in your list, then it's a one-step operation:

content.toArray(new String[content.size()]);

Otherwise you'll have to iterate over each member, applying toString() or whichever method you must use to get the string representation of each list member. For that case there is no shortcut in the JDK.
