Find documents with array that contains a specific value in mongodb using java

Question

According to the answer provided in this link: Find document with array that contains a specific value, i have tried getting the items in java using this statement

searchQuery.put("arrayMine", new BasicDBObject("$in","[xxx]"));
OR
searchQuery.put("arrayMine", new BasicDBObject("$in","xxx"));

But it keeps saying the $in value must be an array while my arrayMine is an array. What should be the correct syntax in java?

Both variants you have are treating the value of BasicDBObject as String.

Use

searchQuery.put("arrayMine", new BasicDBObject("$in", Arrays.asList("xxx"))
