Java I/O Opening Files in External Program

Question

I have a Java program that I am using to scan a directory to look for certain files. It finds the files but now I am trying to get the code to open the files once it finds them, but I am not sure how to do that.

Here a part of my code

File file = new File("/Users/******/Desktop/******");
    String[] A = file.list();

    File[] C = file.listFiles();
for (String string : A) {
    if (string.endsWith(".txt")) {
            System.out.println(string);

        }
        if (string.contains("******")) {

            System.out.println("It contains X file");
        }

    }

I am trying to get it so once it finds the files ending in .txt, it opens all of them

I have tried using Google on how to solve his, I came across .getRuntime() and so I tried

try{
    Runtime.getRuntime().exec("******.txt");
     } catch(IOException e){
            }

But I am not fully understanding how how this works. I am trying to get to so that once it finds the files it opens them. I am not trying to have the IDE open the text on the screen. I want the actual Notepad/TextEdit program to open.

    File[] files = new File("/Users/******/Desktop/******").listFiles();
    for (File f : files) {
        String fileName = f.getName();
        if (fileName.endsWith(".txt")) {
            System.out.println(fileName);

        }
        if (fileName.contains("******")) {
            System.out.println("It contains X file");
        }
    }
