有没有老哥给看一下啊

for example

public class Main {
public static void main(String[] args) {
int score_usually = 50;
System.out.printf("A base:30, score:%.2f\n", score_usually + getTestScore(30));
System.out.printf("B base:60, score:%.2f\n", score_usually + getTestScore(60));
System.out.printf("C base:85, score:%.2f\n", score_usually + getTestScore(85));
System.out.printf("D base:92, score:%.2f\n", score_usually + getTestScore(92));
}

public static double getTestScore(int base) {
double rate[] = {0.6, 0.5, 0.45, 0.4};
double score = 0;
switch (base/60) {
case 0:
score = base * rate[0];
break;
default:
switch (base/80) {
case 0:
score = base * rate[1];
break;
default:
switch (base/90) {
case 0:
score = base * rate[2];
break;
default:
score = base * rate[3];
}
}
}
return score;
}
}

num/10是取整,余数不被计算,所以
分数60-79的值为6.7,
分数80-89的值为8,
分数90-100的值为9.10
