Process large file in java

How to parse large file like 1.2GB where total lines in file is 36259190. How to parse each line to an object and save it in a list.

I get each time an OutOfMemmoryError.

List<Point> points = new ArrayList<>();

public void m2() throws IOException {
    try (BufferedReader reader = Files.newBufferedReader(Paths.get(DATAFILE))) {
        reader.lines().map(s -> s.split(","))
        .skip(0)
        .forEach(p -> points.add(newPoint(p[0], p[1], p[2])));
    }
}


class Point {
    String X;
    String Y;
    String Z;
}
