java.io.InputStreamReader class serves as a bridge between byte streams and character streams: It reads bytes from the input stream and
translates them into characters according to a specified character encoding. The encoding can be set in the constructor, or you can accept the platform's default encoding.
public InputStreamReader(InputStream in)
public InputStreamReader(InputStream in, String encoding)
throws UnsupportedEncodingException
InputStreamReader to System.in with the default encoding, (generally ISO Latin-1):
InputStreamReader isr = new InputStreamReader(System.in);
FileInputStream fis = new FileInputStream("symbol.txt");
InputStreamReader isr = new InputStreamReader(fis, "MacSymbol");
public String getEncoding()
getEncoding() method returns a string containing
the name of the encoding used by this reader.
The other methods just override methods from java.io.Reader,
but behave identically from the perspective of the programmer.
public int read() throws IOException
public int read(char c[], int off, int length) throws IOException
public boolean ready() throws IOException
public void close() throws IOException
