I have searched for long.. Most of answers were about setting up a default constructor. But in my case, the file doesnt have a default constructor. I may be looking at this completely wrong.. So here's hoping some one can help me out..
Thanks in advance :)
Code:
#RequestMapping(value="/retrieve", method=RequestMethod.POST)
public ArrayList<String> listFiles() {
ArrayList<String> listOfFiles =new ArrayList<String>() ;
File folder = new File("E:/uploadedFiles/");
File[] files = folder.listFiles();
for (File file : files) {
if (file.isFile()) {
System.out.println(file.getName());
listOfFiles.add(file.getName());
}
}
return listOfFiles;
}
