【AI Infra】Perfetto性能分析工具指南 Perfetto是一款开源性能分析工具，提供系统级和应用级的活动数据追踪功能。其界面分为四个区域：左侧操作区（包含Trace查看、SQL查询、预置分析等功能）、上方信息区、中间图形化展示区以及下方详细信息区。工具支持快捷键操作（w/s缩放、a/d移动、m标记等），并能高效处理大体积Trace文件。通过Timeline分析可发现性能瓶颈，如案例中update_actor耗时过高的问题，最终定位到CPU offloading导致的MemcpyH2D操作耗时过长，提出了优化方案。Perfetto相比Systrac 阅读详情

网上找的一个题:
4. 字符串练习题(6)中的数据存在文件data.txt中，模板存在文件template.tmpl中，编写函数：
public static String composeMessage(String dataFileName, String templateFileName)
实现将数据文件和模板文件的内容组织成完整消息。
在此基础上实现一个命令行工具，可将数据和模板文件组成的消息存到指定文件中。要求能准确报告出错误原因。命令语法：
java cm -m dataFileName -v templateFileName -o outputFileName
限时：学习20分，编码30分，测试30

数据为:

我打算用map存放这两个文件的数据(data.txt,template.tmpl),Map<String,List<String>>=new HashMap<String,List<String>>,其中key就是表头的数据，list就是每一项的数据。现在的问题是,我怎么把读到一个一维数组的数据，按照数据类型存放到一个list数组中？
