public FastStringReader(String s)
```
    Creates a new string reader.
    
    パラメータ:
    
    s - String providing the character stream.

  - length

public int length()

  - charAt

public char charAt(int index)

public CharSequence subSequence(int start,
                                int end)
```
  - read
```
public int read()
         throws IOException
```
    Reads a single character.
    
    オーバーライド:
    
    read クラス内 Reader
    
    戻り値:
    
    The character read, or -1 if the end of the stream has been reached
    
    例外:
    
    IOException - If an I/O error occurs
  - read
```
public int read(char[] cbuf,
                int off,
                int len)
         throws IOException
```
    Reads characters into a portion of an array.
    
    定義:
    
    read クラス内 Reader
    
    パラメータ:
    
    cbuf - Destination buffer
    
    off - Offset at which to start writing characters
    
    len - Maximum number of characters to read
    
    戻り値:
    
    The number of characters read, or -1 if the end of the stream has been reached
    
    例外:
    
    IOException - If an I/O error occurs
  - skip
```
public long skip(long ns)
          throws IOException
```
    Skips the specified number of characters in the stream. Returns the number of characters that were skipped.
    The ns parameter may be negative, even though the skip method of the Reader superclass throws an exception in this case. Negative values of ns cause the stream to skip backwards. Negative return values indicate a skip backwards. It is not possible to skip backwards past the beginning of the string.
    If the entire string has been read or skipped, then this method has no effect and always returns 0.
    
    オーバーライド:
    
    skip クラス内 Reader
    
    例外:
    
    IOException - If an I/O error occurs
  - ready
```
public boolean ready()
              throws IOException
```
    Tells whether this stream is ready to be read.
    
    オーバーライド:
    
    ready クラス内 Reader
    
    戻り値:
    
    True if the next read() is guaranteed not to block for input
    
    例外:
    
    IOException - If the stream is closed
  - markSupported
```
public boolean markSupported()
```
    Tells whether this stream supports the mark() operation, which it does.
    
    オーバーライド:
    
    markSupported クラス内 Reader
  - mark
```
public void mark(int readAheadLimit)
          throws IOException
```
    Marks the present position in the stream. Subsequent calls to reset() will reposition the stream to this point.
    
    オーバーライド:
    
    mark クラス内 Reader
    
    パラメータ:
    
    readAheadLimit - Limit on the number of characters that may be read while still preserving the mark. Because the stream's input comes from a string, there is no actual limit, so this argument must not be negative, but is otherwise ignored.
    
    例外:
    
    IllegalArgumentException - If readAheadLimit is < 0
    
    IOException - If an I/O error occurs
  - reset
```
public void reset()
           throws IOException
```
    Resets the stream to the most recent mark, or to the beginning of the string if it has never been marked.
    
    オーバーライド:
    
    reset クラス内 Reader
    
    例外:
    
    IOException - If an I/O error occurs
  - close
```
public void close()
```
    Closes the stream and releases any system resources associated with it. Once the stream has been closed, further read(), ready(), mark(), or reset() invocations will throw an IOException. Closing a previously closed stream has no effect.
    
    定義:
    
    close インタフェース内 Closeable
    
    定義:
    
    close インタフェース内 AutoCloseable
    
    定義:

public String toString()
```
