A character stream that collects its output in a string buffer, which can then be used to construct a string.
Closing a StringWriter has no effect. The methods in this class can be called after the stream has been closed without generating an IOException .

public StringWriter append(CharSequence csq)
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.
public StringWriter append(CharSequence csq, int start, int end)
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())
public StringWriter append(char c)
An invocation of this method of the form out.append(c) behaves in exactly the same way as the invocation
out.write(c)
