第五步打开文件流并读取文件内容,如果文件存在,就可以开始进行读取操作。 序列图 下面是一个展示整个流程的序列图,帮助更直观地理解: JavaAppUserFileSystemJavaAppUseralt[File exists][File not found]Start applicationCreate File object (relative path)Get working directoryReturn working directoryCombine paths to...
方法三:使用ClassLoader.getResource()方法 除了使用Class.getResource()方法,我们还可以使用ClassLoader.getResource()方法来获取相对路径。 ClassLoaderclassLoader=MyClass.class.getClassLoader();URLurl=classLoader.getResource("relative/path/to/file.txt");Filefile=newFile(url.getPath());System.out.println...
String b = file2String(f,"GBK"); System.out.println(b); } /** * 通过CLASSPATH读取包内文件,注意以“/”开头 */ publicstaticvoidreadTextA_ByClassPath() { System.out.println("---readTextA_ByClassPath---"); InputStream in = ReadFile.class.getResourceAsStream("/com/lavasoft/res/a....

This method attempts to construct a #isAbsolute relative path that when #resolve(Path) resolved against this path, yields a path that locates the same file as the given path. For example, on UNIX, if this path is "/a/b" and the given path is "/a/b/c/d" then the resulting ...

A pathname, whether abstract or in string form, may be either absolute or relative. An absolute pathname is complete in that no other information is required in order to locate the file that it denotes. A relative pathname, in contrast, must be interpreted in terms of information taken from...
2015年在大物流项目中,给项目团队做了几次Java性能优化和问题排查的分享,不过效果都不是很好。一直觉得偏向技术实践类的东西,单纯的听和单纯的讲收获都很有限,最好的做法是阅读学习-理解-实践-总结,这样的方式。这一份原来是我在阅读《Java性能优化权威指南》时候的阅读笔记,最近整理后在这边做一下分享。
