Does Java's FileWriter object attempt to creat

问题:

I am seeking to clarify what the Java API documentation states about the FileWriter class. The documentation states the following:

constructor:
Constructs a FileWriter object given a file name.

public FileWriter(String fileName)
    throws IOException


fileName - String The system-dependent filename.

IOException - if the named file exists but is a directory rather than a
regular file, does not exist but cannot be created, or cannot be opened
or any other reason

It is not clear to me whether or not the FileWriter object will attempt to create the file specified by the fileName String, although it is clear that the object will check to see if the file is created and an exception thrown if it can not be created.

回答1:

Yes, it will be created (if it does not already exist.) If the file cannot be created, an IOException is thrown.
