本文整理了Java中java.lang.StringBuffer.length()方法的一些代码示例，展示了StringBuffer.length()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。StringBuffer.length()方法的具体详情如下：
包路径：java.lang.StringBuffer
类名称：StringBuffer
方法名：length
[英]Returns the length (character count) of this string buffer.
[中]返回此字符串缓冲区的长度（字符计数）。
