Answer 1

Yes return and print are totally different.

Answer 2

Because you have not print anything.

Answer 3

Abhinav Bhardwaj but it should return the argument of the function

Answer 4

Abhinav Bhardwaj and Airree are return and print statements not same ? have I misunderstood some concepts?

Answer 5

No, they are different, the return just gives a value to the function so if you have the same code:
x = rec(1);
System.out.println(x);
//Outputs 1

Answer 6

It's because you haven't specified anywhere to print in.
The return keyword doesn't print it, it just, well, returns a value.
To print it, you have to do it like this: (in the main method)
System.out.println(rec(1));
Or:
public static int rec(int i) {
System.out.println(i);
}
