java和VB一样，右斜杠是整除

import java.util.Scanner;
public class ScannerDemo {

 
 
 
 /**
  * @param args
  */
 public static void main(String[] args)
 {

  Scanner scanner=new Scanner(System.in);
 
  System.out.print("请输入分数：");
  
  int score=scanner.nextInt();
  
     int level =(int) score/10;
    
  
         System.out.println(level);
    
 }
 
 
 
}
