Java Read Text Column function similar to ReadLine()

I have a text file containing vector information by pin. It looks like this:

PHP Code:

xxxxxxxxxxxxxxxxxxxx pppppppppppppppppppp iiiiiiiiiiiiiiiiiiii nnnnnnnnnnnnnnnnnnnn 12345689111111111122 012345678901 CountPatAdr (Main)(Main) 101000000000000010XXXX 201000000000000010XXXX 301000000000000010XXXX 401000000000000010XXXX 501000000000000010XXXX 601000000000000010XXXX 701000000000000010XXXX 801000000000000010XXXX 901000000000000010XXXX 1001000000000000010XXXX 1101000000000000010XXXX 1201000000000000010XXXX 1301000000000000010XXXX 1401000000000000010XXXX 1501000000000000010XXXX 1601000000000000010XXXX ...

I want to extract the information column by column. So I would like to be able to write or store each pin by line such as: xpin1 11111... xpin2 10000... xpin3 10000... Basically, what I am looking for is exactly the Java readLine() function described here: but instead of reading a text file line-by-line. I want to read column by column. Anyone know of such a function or way to do this?

要实现这个算法，需要进行集合成员的拼接和转换。java做这种集合式的运算不难，但代码繁琐比较麻烦；使用 R 或 python 都比较容易，但没法被 java 主程序集成。用 SPL 也容易完成，并且可以被 java 主程序调用 (参考)，代码如下：

A 1 =file("source.txt").read@n() 2 =A1.to(2,6) 3 =A1.to(14,) 4 =A2.regex("(.*) (.*)";a,b).(b) 5 =A4.new(mid(~,1,1),mid(~,2,1),mid(~,3,1),mid(~,4,1),mid(~,5,1),mid(~,6,1),mid(~,7,1),mid(~,8,1),mid(~,9,1),mid(~,10,1),mid(~,11,1),mid(~,12,1),mid(~,13,1),mid(~,14,1),mid(~,15,1),mid(~,16,1),mid(~,17,1),mid(~,18,1),mid(~,19,1),mid(~,20,1)) 6 =A3.regex("(.*) (.*)";a,b).(b) 7 =A6.new(mid(~,1,1),mid(~,2,1),mid(~,3,1),mid(~,4,1),mid(~,5,1),mid(~,6,1),mid(~,7,1),mid(~,8,1),mid(~,9,1),mid(~,10,1),mid(~,11,1),mid(~,12,1),mid(~,13,1),mid(~,14,1),mid(~,15,1),mid(~,16,1),mid(~,17,1),mid(~,18,1),mid(~,19,1),mid(~,20,1)) 8 =A5|A7 9 =A8.fno().(A8.field(~).concat())

A1：读取source.txt文件内容,将每一行返回成字符串。

A2：取序列第2-6行数据组成新序列。

A3：取14行之后的数据组成新序列。

A4：正则匹配出需要的数据。

A5：将A4拆分成二维表。

A6：正则匹配出需要的数据。

A7：将A6拆分成二维表。

A8：合并2个二维表。

A9：将每列合并成字符串。
