Java Foundation--stringbuffer and StringBuilder

This section describes the differences between 2 string containers

StringBuffer and StringBuilder differences:

1. The same point

Both are containers (variable sequence of characters), which can be used to perform basic "delete and modify" operations on strings.

2. Different points

stringbuffer:jdk1.0 appear, thread synchronization, operation is more time-consuming, but security;

stringbuilder:jdk1.5 appears, the thread is out of sync, because it does not perform synchronization, so the speed is faster than StringBuffer, not secure.
