Hello I am using this code to check that array is present in the HashMap.

public class Test {
    public static void main(String[]arg)
    {
     HashMap<int[],String> map= new HashMap<int[],String>();
     map.put(new int[]{1,2}, "sun");
     System.out.println(map.containsKey((new int[]{1,2})));
    }
}

But this prints False. How can I check that array is present in the HashMap. Thanks in advance.
