Suppose I have two fields source and genre. source can have thousands of
values. I want to read the values in. genre can have 10 values. The values
of the two fields will be changed from time to time. What's the most
convinient way to store and retrieve the values? No database is available.
Initially I planned to use Java property files to store them. But it appears
Java Properties class can retrieve multiple values for the same key. Do I
have to go with the most basic file processing?

No, I'm asking about how to physically store the data. Now I created a file
with thousands of values.

XML文件呢？
或者还是用property file, 把Value的各个值用分隔符分开，但是放在一行

The most convenient way would be just serializing your data
if you are using it with Java only. All you need to do is
keep your data in a bean class and mark it serializable

This is a file that will be manually maintained. So I went with the most
simple file operation to read the file and get the values. I didn't use xml
file format so the users don't have to struggle to create a one thousand
lines xml file. All they need to copy and paste the values into the file,
one value per line. The format is consistent with the source of the values.
Problem is resolved. Thank everyone.
