FileWriterクラスはOutputStreamWriterクラスを継承したクラスで,ファイルに書き込むストリームを提供する。
コンストラクタは,以下のような多くの種類がオーバーロードされている。このクラスで独自に実装されているメソッドはなく,すべてスーパークラスのメソッドを継承する。
- FileWriter(String fileName)
- FileWriter(String fileName, boolean append)
- FileWriter(File file)
- FileWriter(File file, boolean append)
- FileWriter(FileDescriptor fd)
- FileWriter(String fileName, Charset charset)
- FileWriter(String fileName, Charset charset, boolean append)
- FileWriter(File file, Charset charset)
- FileWriter(File file, Charset charset, boolean append)
