I want to use Weka in order to parse an existing json file in java eclipse. I believe this can be done using the JSONLoader class. After I read the classes' specifications (http://weka.sourceforge.net/doc.dev/weka/core/converters/JSONLoader.html#JSONLoader--) I thought that this could be easily done by doing this:
JSONLoader jsonLoader = new JSONLoader(jsonFile);
Then I thought by just doing jsonLoader.getFileDescription() or jsonLoader.getSource() would give me results. This is not how it's done though and I can't find anywhere how to use the JSONLoader class in my java code. So in order not to make this question too broad, how can I create a JSONLoader object that reads a source that is in JSON format?
First of all it has nothing to do with eclipse so you should edit your question.
A brief look at the documentation of JSONLoader(in the link you provided) can tell that you need to set the data source you want to parse using setSource (the constructor is empty):
JSONLoader jsonLoader = new JSONLoader();
File f = new File("PATH_TO_YOUR_JSON_FILE");
jsonLoader.setSource(f); //you can also use InputStream instead of a File
After doing that you can use other methods that parse your JSON:
Instances dataset = jsonLoader.getDataSet();
jsonLoader.getFileDescription();
