Solution

What you need to do here is create a string and keep adding the output of file. To do this, you should use StringBuilder class which is optimal for it. So your code would look something like below

static String Q1(String fileName) {

  StringBuilder builder = new StringBuilder();

try {

for (String line : Files.readAllLines(Paths.get(fileName))) {

builder.append(line);

}

}

catch (IOException ex) {

ex.printStackTrace();

}

return builder.toString();

}
