switch语句实现成绩选择
注意强制转换
import java.util.Scanner;
public class Grade_Switch {
/**
* @param args
*/
public static void main(String[] args) {
// TODO Auto-generated method stub
float score;
Scanner input = new Scanner(System.in);
System.out.println("Please input the score here:");
score = input.nextFloat();//成绩输入
int temp = (int) (score/10);
switch(temp)
{
case 0:
case 1:
case 2:
case 3:
case 4:
case 5: System.out.println("不及格");break;
case 6: System.out.println("及格");break;
case 7: System.out.println("中等");break;
case 8: System.out.println("良好");break;
case 9:
case 10:System.out.println("优秀");break;
}
}
}
