Read a property file and store it in a hashmap

Question

Hi,
I have tried to read a property file and store it in a hashmap. The property-names should be stored in keys and the property-values (after = symbol) in values of the hashmap. any ideas? Is it possible to do this?

yes, but I need the hashmap for another reason. Actually I'm trying to use the properties file to have a dynamic hachmap. I don't want to change the code anytime I want to put a value in the hashmap. therefor I write the "keys" and "values" in a property file and change the property file. That's the reasn why we have property files, isn't it?What's a "dynamic hashmap"? There's no other kind! Whenever someone starts bandying around the word "dynamic" in contexts like this, it usually means there's a simple solution to their problem, that they haven't yet considered, or mistakenly don't believe is applicable to them, because of this "unique" need for something "dynamic". Trust me, you just need to load the file using a Properties object, and you're done. Properties extends Hashtable, which is virtually the same thing as a HashMap. Properties does exactly what you want it to. it's the very reason the class exists
Have you even looked at the javadoc for java.util.Properties yet? I'm betting not, because if you had, you'd know exactly what I meant. And since you haven't, I'm at a bit of a loss as to how you can so easily dismiss the class as useless, despite existing to do exactly what you need
