Java - Read all .txt files in folder

bufferedreader, java

Solution

Something like the following should get you going, note that I use apache commons FileUtils instead of messing with buffers and streams for simplicity...

File folder = new File("/path/to/files");
File[] listOfFiles = folder.listFiles();

for (int i = 0; i < listOfFiles.length; i++) {
  File file = listOfFiles[i];
  if (file.isFile() && file.getName().endsWith(".txt")) {
    String content = FileUtils.readFileToString(file);
    /* do somthing with content */
  } 
}

Problem

Let's say, I have a folder called `maps` and inside `maps` I have `map1.txt`, `map2.txt,` and `map3.txt`. How can I use Java and the `BufferReader` to read all of the `.txt` files in folder `maps` (if it is at all possible)?
