| FileWriter | | public class FileWriter extends OutputStreamWriter (Code) | | Convenience class for writing character files. The constructors of this
class assume that the default character encoding and the default byte-buffer
size are acceptable. To specify these values yourself, construct an
OutputStreamWriter on a FileOutputStream.
Whether or not a file is available or may be created depends upon the
underlying platform. Some platforms, in particular, allow a file to be
opened for writing by only one FileWriter (or other file-writing
object) at a time. In such situations the constructors in this class
will fail if the file involved is already open.
FileWriter is meant for writing streams of characters.
For writing streams of raw bytes, consider using a
FileOutputStream.

| Constructor Summary | |
| public | FileWriter(String fileName)
Constructs a FileWriter object given a file name. | | public | FileWriter(String fileName, boolean append)
Constructs a FileWriter object given a file name with a boolean
indicating whether or not to append the data written. | | public | FileWriter(File file)
Constructs a FileWriter object given a File object. | | public | FileWriter(File file, boolean append)
Constructs a FileWriter object given a File object. | | public | FileWriter(FileDescriptor fd)
Constructs a FileWriter object associated with a file descriptor. |
| FileWriter | | public FileWriter(String fileName) throws IOException(Code) | | Constructs a FileWriter object given a file name.
Parameters:
fileName - String The system-dependent filename.
throws:
IOException - if the named file exists but is a directory ratherthan a regular file, does not exist but cannot becreated, or cannot be opened for any other reason |
| FileWriter | | public FileWriter(String fileName, boolean append) throws IOException(Code) | | Constructs a FileWriter object given a file name with a boolean
indicating whether or not to append the data written.
Parameters:
fileName - String The system-dependent filename.
Parameters:
append - boolean if true, then data will be writtento the end of the file rather than the beginning.
throws:
IOException - if the named file exists but is a directory ratherthan a regular file, does not exist but cannot becreated, or cannot be opened for any other reason |
| FileWriter | | public FileWriter(File file) throws IOException(Code) | | Constructs a FileWriter object given a File object.
Parameters:
file - a File object to write to.
throws:
IOException - if the file exists but is a directory rather thana regular file, does not exist but cannot be created,or cannot be opened for any other reason |
| FileWriter | | public FileWriter(File file, boolean append) throws IOException(Code) | | Constructs a FileWriter object given a File object. If the second
argument is true, then bytes will be written to the end
of the file rather than the beginning.
Parameters:
file - a File object to write to
Parameters:
append - if true, then bytes will be writtento the end of the file rather than the beginning
throws:
IOException - if the file exists but is a directory rather thana regular file, does not exist but cannot be created,or cannot be opened for any other reason
