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

     3      0  1000000000000010XXXX

     7      0  1000000000000010XXXX
     8      0  1000000000000010XXXX
     9      0  1000000000000010XXXX
    10      0  1000000000000010XXXX
    11      0  1000000000000010XXXX
    12      0  1000000000000010XXXX
    13      0  1000000000000010XXXX
    14      0  1000000000000010XXXX
    15      0  1000000000000010XXXX
    16      0  1000000000000010XXXX
    ...

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:
http://java.sun.com/javase/6/docs/ap...redReader.html
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Java 如何调用 SPL 脚本)，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())
