Java reading a file and storing string into an array [duplicate]

Answer 1

To read the file you can take a look at the Scanner Class, this will allow you to iterate over the contents of your text file.

Although what you want to do is possible to achieve with an array data structure, it is not advisable, using something such as an ArrayList will allow you to have a dynamic data structure which can then, if you want, be changed to an array using the toArray() method.

Answer 2

I suggest you use a List<String> (such as ArrayList<String>) and a Scanner (construct it using new Scanner(new File("wordfile.txt")), and use scanner.hasNextLine()/scanner.nextLine()) to read the words.

If you indeed need it to be an array, go through list.toArray in the end.

Answer 3

Steps:

Open a Scanner on the file.

Count all of the lines in the file.

Initialize the array to an array with size equal to the count of the number of lines in the file.

Close the Scanner.

Open a Scanner on the file.

From 0 to yourArray.length - 1, assign the ith index of your array to the current line in the Scanner.

Close the scanner.
