how do i fix this scanner new scanner error?

Question

I get this error when trying to use the Scanner object:

Main.java:105: error: cannot find symbol

The Scanner library is already imported

Here is my code :

Scanner in= new Scanner(System.in);
public int play(int pieces){
    Scanner in= new Scanner(System.in); 
    int num;
    num = in.nextInt();

    return pieces-in;
}

Is any class in your project named `Scanner` ? If **yes** use `java.util.Scanner in = new java.util.Scanner(System.in);` — Shrinivas Shukla, Jul 13 '15 at 18:10
The code you've posted doesn't make sense. What are `pieces` and `in` ? — khelwood, Jul 13 '15 at 18:11
your return statement is not proper `return pieces-in;` `(you can't perform operation on two different data type variable , one is primitive other one is reference type)` also your code is ambiguaous — Prashant, Jul 13 '15 at 18:12
Look in your IDE for line 105, and tell us which line that is. The error is at line 105. The main problem is you're subtracting `in` which is of type `Scanner` from `pieces` which is of type `int`. — 9Deuce, Jul 13 '15 at 18:14
You're also declaring and instantiating the same `Scanner` object twice. You only need to do it once. — 9Deuce, Jul 13 '15 at 18:16

in is you Scanner object. The value you read is in the variable num, you must use that variable in the return statement.

public int play(int pieces){
    Scanner in= new Scanner(System.in); 
    int num;
    num = in.nextInt();

    return pieces-num;
}

Look at this post, is it possible you didn't create the packages structure ? http://stackoverflow.com/questions/6777554/cannot-find-symbol-error-even-on-a-ridiculously-simple-example – Bibz Jul 13 '15 at 18:27
The code is good, I tested it successfully, so it must be something with how you compile or un it. You might also want to check : http://stackoverflow.com/questions/25706216/what-does-a-cannot-find-symbol-compilation-error-mean – Bibz Jul 13 '15 at 18:31
