Java - Read and storing in an array

I want to read the contents of a text file, split on a delimiter and then store each part in a separate array.

For example the-file-name.txt contains different string all on a new line:

football/ronaldo
f1/lewis
wwe/cena

So I want to read the contents of the text file, split on the delimiter "/" and store the first part of the string before the delimiter in one array, and the second half after the delimiter in another array. This is what I have tried to do so far:

try {

    File f = new File("the-file-name.txt");

    BufferedReader b = new BufferedReader(new FileReader(f));

    String readLine = "";

    System.out.println("Reading file using Buffered Reader");

    while ((readLine = b.readLine()) != null) {
        String[] parts = readLine.split("/");

    }

} catch (IOException e) {
    e.printStackTrace();
}

This is what I have achieved so far but I am not sure how to go on from here, any help in completing the program will be appreciated.

You can create two Lists one for the first part and se second for the second part :

List<String> part1 = new ArrayList<>();//create a list for the part 1
List<String> part2 = new ArrayList<>();//create a list for the part 2

while ((readLine = b.readLine()) != null) {
    String[] parts = readLine.split("/");//you mean to split with '/' not with '-'

    part1.add(parts[0]);//put the first part in ths list part1
    part2.add(parts[1]);//put the second part in ths list part2
}

Outputs

[football, f1, wwe]
[ronaldo, lewis, cena]
