 public interface AppendableAn object to whichcharsequences and values can be appended. TheAppendableinterface must be implemented by any class whose instances are intended to receive formatted output from aFormatter.The characters to be appended should be valid Unicode characters as described in Unicode Character Representation. Note that supplementary characters may be composed of multiple 16-bit charvalues.Appendables are not necessarily safe for multithreaded access. Thread safety is the responsibility of classes that extend and implement this interface. Since this interface may be implemented by existing classes with different styles of error handling there is no guarantee that errors will be propagated to the invoker. - Since:

Method Detail- 
appendAppendable append(CharSequence csq) throws IOException Appends the specified character sequence to thisAppendable.Depending on which class implements the character sequence csq, the entire sequence may not be appended. For instance, ifcsqis aCharBufferthen the subsequence to append is defined by the buffer's position and limit.- Parameters:
- csq- The character sequence to append. If- csqis- null, then the four characters- "null"are appended to this Appendable.
- Returns:
- A reference to this Appendable
- Throws:
- IOException- If an I/O error occurs
 
 - 
appendAppendable append(CharSequence csq, int start, int end) throws IOException Appends a subsequence of the specified character sequence to thisAppendable.An invocation of this method of the form out.append(csq, start, end)whencsqis notnull, behaves in exactly the same way as the invocationout.append(csq.subSequence(start, end))- Parameters:
- csq- The character sequence from which a subsequence will be appended. If- csqis- null, then characters will be appended as if- csqcontained 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
- Returns:
- A reference to this Appendable
- Throws:
- IndexOutOfBoundsException- If- startor- endare negative,- startis greater than- end, or- endis greater than- csq.length()
- IOException- If an I/O error occurs

appendAppendable append(char c) throws IOException Appends the specified character to thisAppendable.- Parameters:
- c- The character to append
- Returns:
- A reference to this Appendable
- Throws:
- IOException- If an I/O error occurs
