Storing some filenames in an array in loop

Question

Hi ,
I am getting some file names in a loop like this:
File aDirectory = new File("Data/");
         File[] files = aDirectory.listFiles();
         //String fileret = null;
         for(File file : files){
              String file1 = "Data/"+file.getName()+"/"+file.getName()+".txt";
              String f12str = readTextFile(file1);
              String s1 =f12str.toLowerCase();
         }I need the f12str names outside the loop in an array...How can I do that? It is not defined outside.
I need to store the names in an array.

Hi,
I want to compute something like this:
String file1 = "Data/xyz/xyz.txt";
String file2 = "Data/abc/abc.txt";
String file3 = "Data/efg/efg.txt";
          String f12str = readTextFile(file1);
          String f22str = readTextFile(file2);
          String f32str = readTextFile(file3);By using a new program with a new loop:
File aDirectory = new File("Data/");
         File[] files = aDirectory.listFiles();
         String file1 =null;
         for(File file : files){
              file1 = "Data/"+file.getName()+"/"+file.getName()+".txt";
         }But how can I perform the above operations if I cant even initialize an array of files in file1.
Actually I have to make
file[] = all files;
do same operations as in main file.... like readTextFile and stuff
