3.3.5-replace 3.3.6-其它实例 4-StringBuffer vs StringBuilder 1- 分层继承 当使用文本数据时,Java提供了三种类别,包括String, StringBuffer和StringBuilder。当使用大数据来工作时,你应该用StringBuffer或StringBuilder来优化效率。基本上这三个类有许多相似之处。
For example, if z refers to a string buffer object whose current contents are "start", then the method call z.append("le") would cause the string buffer to contain "startle", whereas z.insert(4, "le") would alter the string buffer to contain "starlet". In general, if sb refers ...
