I am trying to create a file (/data/test/userid/feedid/test.flv)
If that directory does not exist, I get this exception:
java.io.FileNotFoundException
Is there any good way to solve this problem?
I have found commons.io, but there isn't any function that can solve this.
File#mkdirs will create the paths structure denoted by this File. For example
File file = new File("/data/test/userid/feedid/test.flv");
File parent = file.getParentFile();
if (parent.exists() || parent.mkdirs()) {
//...
} else {
throw new IOException("Failed to create output directory " + parent);
}
Something like this must work:
File file = new File("data//test//userid//feedid//test.flv");
file.getParentFile().mkdirs();
FileWriter writer = new FileWriter(file);
Try this
String fileLocation= //your location to store;
File fileDir=new File(fileLocation);
if(!fileDir.exists())
{
fileDir.getParentFile().mkdirs(); // to create directory if not exists
}
mkdirs call fails? Do you have to do another fileDir.exists() to check for it? Seems like a waste of effort to me. Right idea though
mkdirs can fail - From the docs "Note that if this operation fails it may have succeeded in creating some of the necessary parent directories"if (fileDir.exists() || fileDir.mkdirs()) {...} assuming that fileDir is the path you want to create..Here's what you need to do first:
File dir = new File("/data/test/userid/feedid");
if (!dir.exists()){
dir.mkdir();
}
