File processing task

Question

Hello, everybody!
Task for resolve:
I have *.txt file with constans which looks like:
#define FIRST_CONSTANT 101
#define SECOND_CONSTANT 10101
#define THIRD_CONSTANT 7877
etc...
So, I need to parse it and have the java.util.HashMap where keys - names of constants, and values - values of constants which in file.
Ok, I started to think: how may I make my work easy?
I found java.util.Properties class. So I may load constans and have the Properties object wich is son of HashMap, but I think: how may I delete #define string? How make it easy? Maybe load file in memory using java.nio or some file filters? What do you think?

I think the best way is to read the file line by line and tokenize it using StringTokenizer (If your file contains other types of lines that need to be ignored, use the String class methods to detect them and then ignore them)
Here are some sample codes:
