StringWriter JDK 1.6)

public StringWriter append (char c) [Overrides Writer]

Appends the specified character to this writer.

An invocation of this method of the form out.append(c) behaves in exactly the same way as the invocation

     out.write(c)

Returns: This writer
Parameters:
- c - The 16-bit character to append
Since: 1.5

public StringWriter append (CharSequence csq) [Overrides Writer]

Appends the specified character sequence to this writer.

An invocation of this method of the form out.append(csq) behaves in exactly the same way as the invocation

     out.write(csq.toString())

Depending on the specification of toString for the character sequence csq, the entire sequence may not be appended. For instance, invoking the toString method of a character buffer will return a subsequence whose content depends upon the buffer's position and limit.
Returns: This writer
Parameters:
- csq - The character sequence to append. If csq is null, then the four characters "null" are appended to this writer.
Since: 1.5

public StringWriter append (CharSequence csq, int start, int end) [Overrides Writer]

Appends a subsequence of the specified character sequence to this writer.

An invocation of this method of the form out.append(csq, start, end) when csq is not null, behaves in exactly the same way as the invocation

     out.write(csq.subSequence(start, end).toString())

Returns: This writer
Parameters:
- csq - The character sequence from which a subsequence will be appended. If csq is null, then characters will be appended as if csq contained the four characters "null".
- start - The index of the first character in the subsequence
- end - The index of the character following the last character in the subsequence
Throws:
- IndexOutOfBoundsException - If start or end are negative, start is greater than end, or end is greater than csq.length()
Since: 1.5
