I'm requesting something from a database, as a result i get the following object:

"[Ljava.lang.Object;@64a294a6"

What is that? Can I do anything useful with that and convert it into something else?

        // FIXME
    List singleTasks = Arrays.asList((Object[]) objClient.execute("execute_kw",
            Arrays.asList(db, uid, password, "project.task", "search_read",
                    Arrays.asList(Arrays.asList(
                            Arrays.asList("active", "=", true))),
                    new HashMap() {{
                        put("fields", Arrays.asList("display_name", "total_hours", "project_id", "user_id"));
                        HashMap map = this;
                        System.out.println(map.get("fields"));
                    }}
                )));

    HashMap map = (HashMap)singleTasks.get(0);
    System.out.println(map.get("project_id").getClass().getName());

getClass.getName only gives me: "[Ljava.lang.Object;" as result.

If you selecting anything from the DB you should know what it is – Jens Jun 02 '17 at 12:22
Please add a sample code. – mrhallak Jun 02 '17 at 12:22
Add something like: System.out.println(yourResultObject.getClass().getName()); to get the Type of the Result – huellif Jun 02 '17 at 12:23
`[Ljava.lang.Object;` means `Object[]`. If you want to see values in the array, do what the answer in the duplicate link says. – Andreas Jun 02 '17 at 12:39
