StringBuffer buffer =new StringBuffer();
buffer.append(name);
buffer.append(DELIM);
buffer.append(number);
buffer.append(DELIM);
buffer.append(date);
buffer.append(DELIM);
buffer.append(scheme);
buffer.append(DELIM);
buffer.append(value);
return buffer.toString();
}
may i know how do i can connect this non static method intopublicstaticvoid main(String[] args)
?
