    toByteArray
    +
```
public static byte[] toByteArray(InputStream in)
+                          throws IOException
```
    +
    Reads the input stream and returns its contents as a byte array.
    +
    Parameters:
    in - the input stream to read from.
    +
    Returns:
    the byte array
    +
    Throws:
    +
    IOException - if an I/O error occurs
    +
  + + + +
  - +
    copy
    +
```
public static long copy(InputStream input,
+        OutputStream output)
+                 throws IOException
```
    +
    Copies all the contents from the given input stream to the given output stream.
    +
    Parameters:
    input - the input stream
    output - the output stream
    +
    Returns:
    the number of bytes that have been copied
    +
    Throws:
    +
    IOException - if an I/O error occurs
    +
  + + + +
  - +
    populateBuffer
    +
```
public static long populateBuffer(InputStream in,
+                  byte[] buffer)
+                           throws IOException
```
    +
    Populates the given buffer with data read from the input stream. If the data doesn't + fit the buffer, only the data that fits in the buffer is read. If the data is less than + fits in the buffer, the buffer is not completely filled.
    +
    Parameters:
    in - the input stream to read from
    buffer - the buffer to fill
    +
    Returns:
    the number of bytes written to the buffer
    +
    Throws:
    +
    IOException - if an I/O error occurs
    +
  + + + +
  - +
    closeQuietly
    +
```
public static void closeQuietly(InputStream input)
```
    +
    Unconditionally close an InputStream. +
    + Equivalent to InputStream.close(), except any exceptions will be ignored. + This is typically used in finally blocks.
    +
    Parameters:
    input - the InputStream to close, may be null or already closed
    +
  + + + +
  - +
    closeQuietly
    +
```
public static void closeQuietly(Reader input)
```
    +
    Unconditionally close an Reader. +
    + Equivalent to Reader.close(), except any exceptions will be ignored. + This is typically used in finally blocks.
    +
    Parameters:
    input - the Reader to close, may be null or already closed
    +
  + + + +
  - +
    closeQuietly
    +
```
public static void closeQuietly(Writer output)
```
    +
    Unconditionally close a Writer. +
    + Equivalent to Writer.close(), except any exceptions will be ignored. + This is typically used in finally blocks.
    +
    Parameters:
    output - the Writer to close, may be null or already closed
    +
  + + + +
  - +
    closeQuietly
    +
```
public static void closeQuietly(OutputStream output)
```
    +
    Unconditionally close an OutputStream. +
    + Equivalent to OutputStream.close(), except any exceptions will be ignored. + This is typically used in finally blocks.
    +
    Parameters:
    output - the OutputStream to close, may be null or already closed
    +
  +
