List all files from a directory recursively with Java
- by Hultner
Okay I got this function who prints the name of all files in a directory recursively problem is that it's very slow and it gets the stuff from a network device and with my current code it has to access the device time after time.
What I would want is to first load all the files from the directory recursively and then after that go through all files with the regex to filter out all the files I don't want. Unless anyone got a better suggestion. I've never before done anything like this.
public static printFnames(String sDir){
File[] faFiles = new File(sDir).listFiles();
for(File file: faFiles){
if(file.getName().matches("^(.*?)")){
System.out.println(file.getAbsolutePath());
}
if(file.isDirectory()){
printFnames(file.getAbsolutePath());
}
}
}
This is just a test later on I'm not going to use the code like this, instead I'm going to add the path and modification date of every file which matches an advanced regex to an array.
