| /** |
| * An InputStreamReader is a bridge from byte streams to character streams: It |
| * reads bytes and decodes them into characters using a specified {@link |
| * java.nio.charset.Charset charset}. The charset that it uses |
| * may be specified by name or may be given explicitly, or the platform's |
| * default charset may be accepted. |
| * |
| * <p> Each invocation of one of an InputStreamReader's read() methods may |
| * cause one or more bytes to be read from the underlying byte-input stream. |
| * To enable the efficient conversion of bytes to characters, more bytes may |
| * be read ahead from the underlying stream than are necessary to satisfy the |
| * current read operation. |
| * |
| * <p> For top efficiency, consider wrapping an InputStreamReader within a |
| * BufferedReader. For example: |
| * |
| * <pre> |
| * BufferedReader in |
| * = new BufferedReader(new InputStreamReader(System.in)); |
