How'd you read an array of arrays of Integers from config?

I wanna read an array that looks like this from the config.yml:
coords:
[
[1, 1, 1],
[2, 2, 2],
[3, 3, 3]
]

So that what I end up with is something like List<Integer[]>
And I don't know what to program to read this. How'd you do this?

 

@DaDev I assume what you have in your configuration file is a list of strings.

I won't bother trying to explain this without code, so I'm just gonna spoon-feed you. However, I will try to explain along the way.

Code:Java

// Get the list of arrays from the config
// The string representation (#toString) of this list will look like this:
// "[[1, 1, 1], [2, 2, 2], [3, 3, 3]]"
List<String> list = config.getStringList(/* your path */);
 
// Declare and initialize a 2d int array with the same size as the list
// We will fill this array with your arrays
int[][] array = new int[list.size()][];
 
// Loop the list of arrays
for (int index = 0; index < list.size(); index++) {
    // Get the string representation of the array. This could look like:
    // "[1, 1, 1]"
    String string = list.get(index);
 
    // Initialize the array at array[index]
    // First we remove the square brackets from the string
    // "1, 1, 1"
    // Then we split the string into a string array with the delimiter ", "
    // ["1", "1", "1"]
    // Then we map the stream to an IntStream by parsing all the strings in the array 
    // Finally, we get an int array from the IntStream
    array[index] = Arrays
        .stream(string.substring(1, string.length() - 1).split(", "))
        .mapToInt(Integer::parseInt)
        .toArray();
}
 
// That's it. Now you have a 2d int array containing your data.
// We can print it using Arrays#deepToString(Object[])
System.out.println(Arrays.deepToString(array));
// "[[1, 1, 1], [2, 2, 2], [3, 3, 3]]"

If you actually need a List<Integer[]> (or List<int[]>), then you can simply replace the 2d int array.
