How to put value in HashMap?

Question

I have a Map

Map<String,String[]> data = HashMap<String,String[]>();

and want to put value in it. like

"key":["value1","value2"]

I try it but get error:

data.put("key",["value1","value2"]);//syntax error

Answer 1

You could try using the Array initializer for fixed size string arrays like following

    Map<String, String[]> data = new HashMap<>();
    data.put("key", new String[]{"val1", "val2"});

This should definitely work
