Path resolve(Path other):将给定的Path解析为当前路径的子路径。 Path relativize(Path other):计算从当前路径到给定路径的相对路径。 路径信息 String getFileName():返回路径中的文件名部分。 Path getParent():返回路径的父路径。 Path getRoot():返回路径的根组件。 路径转换 Path toAbsolutePath():将相对路...
Path absolute= Paths.get("/Users/lujiafeng/Desktop/SpringBoot-Learning/Java_Test/src/cc.imi");//绝对路径Path relative = Paths.get("src/cc.imi");//相对路径 注:在project中,相对路径的根目录是project的根文件夹 Path getParent() 返回父路径,或者在该路径没有父路径时,返回null。 Path getFileNam...
3)File和Path之间的转换,File和URI之间的转换: File file = new File("C:/my.ini"); Path p1 =file.toPath(); p1.toFile(); file.toURI(); 1. 2. 3. 4. 4)创建一个文件: Path target2 = Paths.get("C:\\mystuff.txt"); //Set perms = PosixFilePermissions.fromString("rw-rw-rw-")...
getFileNameFromPath(path: String?) 通过FilePath获取文件名 getFileNameFromUri(uri: Uri?) 通过Uri获取文件名 createFile(filePath: String?, fileName: String?, overwrite: Boolean = false):File? 创建文件,同名文件创建多次会跳过已有创建新的文件,如:note.txt已存在,则再次创建会生成note(1).txt create...
