} AboveProgramThe following error occurs: Java. io. charconversionexception: Not an ISO 8859-1 character: No. The cause is that the binary stream output by stream does not encode the character. stream can only use characters encoded by ISO 8859-1, the text information output by writer is encoded by the system.
