贴出了代码和执行结果。 Basically,StringBuffer methods are synchronized while StringBuilder are not. 一般使用StringBuidler,除非你想在线程间共享一个buffer。

Learn about the differences between equals, matches, and compareTo methods in Java String comparison. Understand how to effectively compare strings in your Java applications.
StringBuffer vs StringBuilder Java is a very popular object oriented language. In Java, the String class is provided to hold a sequence of characters that cannot be modified (once initialized). Alternatively, Java programming language provides two types of mutable sequences of characters. That is,...
4. String、StringBuilder和StringBuffer 4.1 继承结构 4.2 主要区别 1. “+”连接符 1.1 “+”连接符的实现原理 Java语言为“+”连接符以及对象转换为字符串提供了特殊的支持,字符串对象可以使用“+”连接其他对象。其中字符串连接是通过 StringBuilder(或 StringBuffer)类及其append 方法实现的,对象转换为字符串是...
