Answer 1

int i=new int(); is valid statement in java

Answer 2

(c) int i=new int();

Explanation:  

• Here int - datatype , I variable   New - keyword which we  are used to create an object in the heap area  (at run time )  Again we have to mention the object name (constructor).

• New int[] means initialize an array object named arr and has a given number of elements ,we can choose any number you want ,but it will be of the type declared yet.

• In Java you have int and Integer . Integer is a wrapper class for int so logically you would need to create a new Integer like this. Integer

        i = new Integer(5); You can definitely do this, and it's completely valid.
