如何修改它使得能够正常输出S的值？

import java.util.Scanner;

public class d {
public static void main(String[] args) {
Scanner in =new Scanner(System.in);
int number;
int n =0;
int m =0;
int s =0;
number = in.nextInt();
if (n =sm) {
s =n/m;
System.out.println("个数="+s);
}
else(n >sm){
s =n/(m-1/6m);
System.out.println("个数="+s);
}
else(n <sm){
System.out.println("个数为0");
}

}

}
