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.
append 在接口中 java.lang.Appendableappend 在类中 java.io.Writercsq - The character sequence to append. If csq is
null, then the four characters "null" are
appended to this writer.public BBossStringWriter append(java.lang.CharSequence csq, int start, int end)
