package hello;

public class Hello {

public static void main(String[] args) {

// TODO Auto-generated method stub

int foot;

double inch;

Scanner in=new Scanner(System.in);

foot=in.nextInt();

inch=in.nextDouble();

System.out.println((foot+inch/12.0)*0.3048);

}

}

Scanner in=new Scanner(System.in);这一行哪里有错啊，请各位大神帮忙看下呗
