如何在java中使用Math.random()每行打印10个数字？

public class RandomNumbers {
    public static void main(String[] args) {
        final int ROWS = 10;
        final int COLUMNS = 10;

        for (int i = 0; i < ROWS; i++) {
            for (int j = 0; j < COLUMNS; j++) {
                double randomNum = Math.random();
                System.out.printf("%.2f ", randomNum);
            }
            System.out.println();
        }
    }
}
