Reading .ini files

[Nountylegre]

I'm in a process of translating some old code and I'm stuck on reading some specific ".ini" files, I use

java.util.Properties

like this:

Properties prop = new Properties();
prop.load(new FileInputStream("sample.ini"));
prop.forEach((key, value) -> System.out.println("Key : " + key + ", Value : " + value));

This is the "sample.ini":
[Sec1]
Key1.1=Val1.1
Key1.2=Val1.2
[Sec2]
Key2.1=Val2.1

But the section's end up being read as keys, this is what I get as an output:
Key : Key1.1, Value : Val1.1
Key : Key1.2, Value : Val1.2
Key : [Sec2], Value :
Key : Key2.1, Value : Val2.1
Key : [Sec1], Value :

If needed, I could work with this and handle the section names myself, but then the problem is that the data is not stored in the same order as it was in the input file.
