Java 基本数据类型包装类

public class Text
{
    public static void main(String[] args)
    {
        double[][] d;
        String s = "1,2;3,4,5;6,7,8";

        String[] sFirst = s.split(";");
        d = new double[sFirst.length][];

        for (int i = 0; i < sFirst.length; i++)
        {

            String[] sSecond = sFirst[i].split(",");
            d[i] = new double[sSecond.length];

            for (int j = 0; j < sSecond.length; j++)
            {
                d[i][j] = Double.parseDouble(sSecond[j]);
            }

        }

        for (int i = 0; i < d.length; i++)
        {
            for (int j = 0; j < d[i].length; j++)
            {
                System.out.print(d[i][j] + " ");
            }
            System.out.println();
        }
    }
}
