Java-给会员打折

根据是否为会员及购物金额来打折

package com.itheima.fiest;
import java.util.Scanner;

public class bu {
	public static void main(String[] args) {
		Scanner input=new Scanner(System.in);	
		System.out.print("请输入是否是会员：是/否");
		String a=input.next();
		System.out.print("请输入购物金额：");
		int b=input.nextInt();
		double	c=b*0.75;
		double d=b*0.8;
		double e=b*0.9;
		if(a.equals("是")) {
		    if(b>=200) {
				System.out.print("实际支付："+c);
			}
			else if(b<200) {
			System.out.	println("实际支付："+d);
			}   //注意大括号的包含范围，包错了则否之后的内容输出不了
		}else if(a.equals("否")&&(b>=100)) {  
					System.out.print("实际支付："+e);
			} else {
				System.out.print("实际支付："+b);
			}
				
			}
}

根据会员积分来打折

package com.itheima.fiest;
import java.util.Scanner;

public class zuoye3 {
	public static void main(String[] args) {
		Scanner input=new Scanner(System.in);
		System.out.print("请输入会员积分:");
		int x=input.nextInt();    //积分
	if (x>=8000) {
	    System.out.println("该会员享受的折扣是:0.6");
	}else if(x>=4000){
		 System.out.println("该会员享受的折扣是:0.7");
	}else if(x>=2000) {
		System.out.println("该会员享受的折扣是:0.8");
	}else if(x<200) {
		System.out.println("该会员享受的折扣是:0.9");
	}
     }
}
