我在字符串中有一个完整的一维数据数组。我需要将此一维数组转换为双数组以进行计算。但我无法弄清楚。如果我能弄清楚,那就太好了。我不确定,但如果我可以在数据文件中读取双精度并解析数据之间的空白,那也很棒。ps 数据被排列为坐标而不是如下所示的聚束,但我这样做的方式不会被读取为 x 和 y,而只会被读取为 1d 数组线。
代码:
file = new File("subtractedvectors.txt");
scan = new Scanner(file);
String [] subarray = new String[40];
for(int row = 0; row < subarray.length; row++)
{
subarray[row] = scan.nextLine();
}
for(int row = 0; row < subarray.length; row++)
{
System.out.println(subarray[row] + " ");
}
