如果楼主觉得还不行，自己在这个基础上改一下下代码肯定就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("请输入会员积分：");
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("该会员享受的折扣是：");
System.out.println(count + "折");
}
}
运行测试：
请输入会员积分：
5000
该会员享受的折扣是：
0.7折
请输入会员积分：
3420
该会员享受的折扣是：
0.8折
有一问题，如果积分超过8000是几折？
public static void main(String args[]) {
//声明一个存放会员信息的list集合，会员信息由编号和积分组成一个map
ArrayListMapObject, String list = new ArrayListMapObject, String();
boolean flag=false;//没有找到相同的会员编号
while(1==1){
Scanner scan = new Scanner(System.in);
System.out.println("请输入会员编号：");
String bh = scan.nextLine();
System.out.println("请输入会员积分：");
String jf = scan.nextLine();
if(list!=null list.size()0){
for (int i = 0; i list.size(); i++) {//循环存放历史输入会员信息的集合
MapObject, String m = list.get(i);
if(bh.equals(m.get("bh"))){//将当前输入的会员编号和已输入的相同时
flag=true;//已找到
}
}
}
if (flag==true) {//已找到
System.out.println("所有输入的会员信息如下：");
for (int i = 0; i list.size(); i++) {//输出所有的会员信息
MapObject, String m = list.get(i);
System.out.println("会员编号："+m.get("bh")+"-----会员积分："+m.get("jf")+"");
}
//结束循环输入
break;
}else{//没有找到相同信息时，存放进list集合
MapObject, String map = new HashMapObject, String();
map.put("bh", bh);
map.put("jf", jf);
list.add(map);//将输入的会员信息存放入list
}
}
}
import java.util.Scanner;
public class Test1 {
public static void main(String[] args) {
System.out.println("请输入会员积分:");
Scanner sc=new Scanner(System.in);
int a=sc.nextInt();
sc.close();
if(a200){
System.out.println("该会员享受的折扣是:0.9");
}else if(a=2000a=4000){
System.out.println("该会员享受的折扣是:0.8");
}else if(a=4000a=8000){
System.out.println("该会员享受的折扣是:0.7");
}else if(a=8000){
System.out.println("该会员享受的折扣是:0.6");
}
}
}
我自己写的，运行没问题，如果有小问题，欢迎指出
练习一：
Customer类：
package com.wxws.sms;
public class Customer {
/**
* @param args
*/
String CustNumber;
int CustPoint;
}
--------------------------------分隔符------------------------------------
CustManager类：
package com.wxws.sms;
import java.util.*;
public class CustManager {
Customer customers[]=new Customer[100];
public void CustAdd(Customer cust) {
// TODO Auto-generated constructor stub
for(int i=0;icustomers.length;i++){
if(customers[i]==null){
customers[i]=cust;
break;
}
}
}
public void showCustomer(){
System.out.println("***Customers List***");
System.out.println("number\tpoint");
for(int i=0;icustomers.length;i++){
if(customers[i]!=null){
System.out.println(customers[i].CustNumber+"\t"+customers[i].CustPoint);
}
}
}
/**
* @param args
*/
public static void main(String[] args) {
// TODO Auto-generated method stub
Customer run=new Customer();
CustManager move=new CustManager();
@SuppressWarnings("resource")
Scanner input=new Scanner(System.in);
System.out.print("Please input your Vip number:");
run.CustNumber=input.next();
System.out.print("Please input your Vip point:");
run.CustPoint=input.nextInt();
move.CustAdd(run);
move.showCustomer();
}
}
---------------------------------------------分割符号---------------------------------------------------
练习二（将Customer类的属性改成数组）：
package com.wxws.sms;
public class Customer {
/**
* @param args
*/
String CustNumber[]=new String[100];
int CustPoint[]=new int[100];
}
---------------------------------------------分割符号---------------------------------------------------

if(customers[i]==null){
customers[i]=cust;
break;
}
}
}
public void showCustomer(){
System.out.println("***Customers List***");
System.out.println("number\tpoint");
for(int i=0;icustomers.length;i++){
if(customers[i]!=null){
System.out.println(customers[i].CustNumber[i]+"\t"+customers[i].CustPoint[i]);
}
}
}
public int searchScore(String custNo){
int point=1;
for(int i=0;icustomers.length;i++){
if(customers[i]!=null){
if((customers[i].CustNumber[i]).equals(custNo)){
System.out.println("The number of Vip's point is:"+customers[i].CustPoint[i]);
point=customers[i].CustPoint[i];
}
}
}
return point;
}
/**
* @param args
*/
public static void main(String[] args) {
// TODO Auto-generated method stub
Customer run=new Customer();
CustManager move=new CustManager();
@SuppressWarnings("resource")

for(int i=0;i4;i++){
System.out.print("Please input your Vip number:");

move.CustAdd(run);
}
move.showCustomer();
System.out.print("Please input the Vip number you want to check:");
String custNum=input.next();
move.searchScore(custNum);
}
}
