Why don't you run the program and tell us what the output is?

Then if there's something about the output you got that you don't understand then come back with your questions.

Please note what it says on the title page of this forum

We're all here to learn, so when responding to others, please focus on helping them discover their own solutions, instead of simply providing answers.

It does not help the OP to be told the answer like that; it reduces the educational value of the discussion. Please don't be annoyed, but I have pulled rank and removed part of your pots.
It might be worth reading about overloading in the Java Language Specification, but it is by no means easy to read. You may need to go on to ยง15.12.2.

The output will be 'object array' it will always give precedence to array argument method, if it is not present the output will be 'object'.

No, that is not correct.

In a case of overloading, the compiler chooses the method whose parameter type is more specific. A null might be an Object or an array of Objects. An array of Objects is more specific; an array of Objects is an Object but an Object is (usually) not an array of objects. So Object[] is more specific and that is chosen by preference.
This shows a pitfall of overloading; it is not obvious to the reader which method is chosen.
