FileWriter Class

Definition

Writes text to character files using a default buffer size.

Attributes

Remarks

Writes text to character files using a default buffer size. Encoding from characters to bytes uses either a specified java.nio.charset.Charset charset or the platform's java.nio.charset.Charset#defaultCharset() default charset.

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.

The FileWriter is meant for writing streams of characters. For writing streams of raw bytes, consider using a FileOutputStream.

Constructors

FileWriter(File, Boolean)

Constructs a FileWriter given the File to write and a boolean indicating whether to append the data written, using the platform's java.

FileWriter(File, Charset, Boolean)

Constructs a FileWriter given the File to write, java.

FileWriter(File, Charset)

Constructs a FileWriter given the File to write and java.

FileWriter(File)

Constructs a FileWriter given the File to write, using the platform's java.

FileWriter(FileDescriptor)

Constructs a FileWriter given a file descriptor, using the platform's java.

FileWriter(IntPtr, JniHandleOwnership)

A constructor used when creating managed representations of JNI objects; called by the runtime.

FileWriter(String, Boolean)

Constructs a FileWriter given a file name and a boolean indicating whether to append the data written, using the platform's java.

FileWriter(String, Charset, Boolean)

Constructs a FileWriter given a file name, java.

FileWriter(String, Charset)

Constructs a FileWriter given a file name and java.

FileWriter(String)

Constructs a FileWriter given a file name, using the platform's java.
