Java: YAML file handling

I am using snakeyaml to handle a yaml config file in Java.

My YAML file structure is this:

config.yml 

User1: "John Doe"
User2: "Jane Smith"
User3: "James Doe"

When I do:

Yaml yaml = new Yaml();
Map<String, String> data = new HashMap<String, String>();
data.put("KR", "test");
String output = yaml.dump(data);
FileWriter f = new FileWriter("config.yml");
f.write(output);

Nothing is written to the config file.

I want to write my key values to the config.yml file.

Solution

  • You don't seem to be closing your FileWriter. You might need to specify the path as well,

    FileWriter f = new FileWriter("c:/config.yml"); // for c:\\config.yml
f.write(output);
f.close();
