A relative pathname, in contrast, must be interpreted in terms of information taken from some other pathname. By default the classes in the java.io package always resolve relative pathnames against the current user directory. This directory is named by the system property user.dir, and is ...
We can use the relative path to locate a file resource in the current working directory. See the example below. importjava.io.File;publicclassSimpleTesting{publicstaticvoidmain(String[]args){String filePath="files/record.txt";File file=newFile(filePath);String path=file.getPath();System.out...
Where both paths have a root component then it is implementation dependent if a relative path can be constructed. If this path and the given path are #equals equal then an empty path is returned. For any two #normalize normalized paths p and q, where q does not have a root component, ...
