Java – how do I force MKDIR to overwrite an existing directory?
•
Java
I need my program to create a directory with a specific name and overwrite any existing directory with that name At present, my program seems unable to overwrite the directory Is there any way to force coverage?
private boolean makeDirectory(){ File file = new File(TEMP_DIR_PATH + "/" + clipName); if (file.mkdir()) { return true; } else { System.err.println("Failed to create directory!"); return false; } }
Edit: now I am trying the following operation, but the program does not detect the existence of the directory, even if it does exist
private boolean makeDirectory(String path){ File file = new File(path); if (file.exists()) { System.out.println("exists"); if (file.delete()) { System.out.println("deleted"); } } if (file.mkdir()) { return true; } else { System.err.println("Failed to create directory!"); return false; } }
Solution: (if someone needs to know in the future...) I finally did this:
private boolean makeDirectory(String path){ if (Files.exists(Paths.get(path))) { try { FileUtils.deleteDirectory(new File(path)); } catch (IOException ex) { System.err.println("Failed to create directory!"); return false; } } if (new File(path).mkdir()) { return true; } return false; }
Solution
If a directory exists, you must first delete it and then recreate it
Using java. nio. file. Files
if (Files.exists(path)) { new File("/dir/path").delete(); } new File("/dir/path").mkdir();
If you have FileUtils, this might be better because it avoids actually deleting the directory you want there:
import org.apache.commons.io.FileUtils if (Files.exists(path)) { FileUtils.cleanDirectory( new File("/dir/path")); } else { new File("/dir/path").mkdir(); }
