求助！！把字符串放到二维数组（double类型）中，结果为什么是这样？

Question

package com.string;

public class Array {

public static void main(String[] args) {

// TODO Auto-generated method stub

String s = "1,2;3,4,5;6,7,8";

String[] str = s.split(";");

String[][] str2 = new String[str.length][];

double a[][] = new double[str2.length][];

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

str2[i] = str[i].split(",");

}

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

a[i] = new double[str2[i].length];

for(int j =0; j<a[i].length; j++) {

//a[i][j] = Integer.parseInt(str2[i][j]);

//System.out.print(a[i][j] + ' ');

a[i][j] = Double.parseDouble(str2[i][j]);

System.out.println(a[i][j] + ' ');

}

System.out.println();

}

}

}

代码没有问题，只是你这句是怎么回事了System.out.println(a[i][j] + ' '); 完全没必要啊  改了吧System.out.println(a[i][j] );改了就ok了
