toString ()Returns a String object that represents the Integer value. Static String toString (int i)Returns a String object that represents the specified integer. Static String toString (int i, int radix)Returns the string representation of the first argument, using the cardinality specified by the second argument.

. In addition, because the StringBuffer is thread-safe, the concept of thread on the follow-up has a special chapter to introduce, so in multithreaded programs can also be very convenient to use, but the implementation of the program efficiency is relatively slow. Initialization of 0.StringBuffer objects The initialization of a StringBuffer object is not the same as the initialization of a string class, Java
