↳ | java.io.Writer | |
↳ | java.io.StringWriter |
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.

Create a new string writer using the default initial string-buffer size.
Create a new string writer using the specified initial string-buffer size.
initialSize | The number of char values that will fit into this buffer before it is automatically expanded |
---|
IllegalArgumentException | If initialSize is negative |
---|
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.
csq | The character sequence to append. If csq is null, then the four characters "null" are appended to this 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())
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 |
IndexOutOfBoundsException | If start or end are negative, start is greater than end, or end is greater than csq.length() |
---|
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)
c | The 16-bit character to append |
