平面文本文件解析

Question

I have a rather complex flat file that I need to parse in Java, but I can't find any libraries that fit my needs.

Essentially, I have a file consisting of a single line of the format: [num num num num]
Example: [0.1 0.2 15 30]

This is followed by series of two-field CSV formatted lines: num, num
Example: 1.0000E+01, 5.7104E-02

This pattern is repeated, so the file consists of blocks that include a header and some data. Here's an example of a whole file (truncated to only three blocks): http://pastebin.com/q3VfRtmF

I need to convert that file into an array of "FluxSet" objects, as defined here: http://pastebin.com/knUFQuVY

A Pair is defined here: http://pastebin.com/s5Ehqpab

Does anyone know of a library applicable to this kind of parsing?

Thanks, taktoa

如果输入文件定义正确，则编写一个简单的文件读取器，逐行读取文件，然后执行简单的String.split()和Integer.parseInt()或任何其他适用的方法，最后填充所需的文件对象与您刚刚解析的数据。
