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)	Constructs a `FileWriter` given the `File` to write, using the platform's java.
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)	Constructs a `FileWriter` given the `File` to write and java.
FileWriter(File, Charset, Boolean)	Constructs a `FileWriter` given the `File` to write, 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)	Constructs a `FileWriter` given a file name, using the platform's java.
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)	Constructs a `FileWriter` given a file name and java.
FileWriter(String, Charset, Boolean)	Constructs a `FileWriter` given a file name, java.
