如果樓主覺得還不行，自己在這個(gè)基礎(chǔ)上改一下下代碼肯定就OK了
Java程序：
import java.util.Scanner;
public class xll {
public static void main(String[] args) {
int score;
double count = 1.0;
Scanner input = new Scanner(System.in);
System.out.println("請(qǐng)輸入會(huì)員積分：");
score = input.nextInt();
if(score 2000)
count = 0.9;
else if(score 4000)
count = 0.8;
else if(score 8000)
count = 0.7;
System.out.println("該會(huì)員享受的折扣是：");
System.out.println(count + "折");
}
}
運(yùn)行測(cè)試：
請(qǐng)輸入會(huì)員積分：
5000
該會(huì)員享受的折扣是：
0.7折
請(qǐng)輸入會(huì)員積分：
3420
該會(huì)員享受的折扣是：
0.8折
有一問題，如果積分超過8000是幾折？

我自己寫的，運(yùn)行沒問題，如果有小問題，歡迎指出
練習(xí)一：
Customer類：
package com.wxws.sms;
public class Customer {
/**

*/
String CustNumber;
int CustPoint;
}
--------------------------------分隔符------------------------------------
CustManager類：

break;
}
}
