java - how do i fix this scanner new scanner error? -

i error when trying use scanner object:

main.java:105: error: cannot find symbol 

the scanner library imported

here 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; } 

in scanner object. value read in variable num, must use variable in return statement.

public int play(int pieces){     scanner in= new scanner(system.in);      int num;     num = in.nextint();      return pieces-num; }
