一、优惠规则

输入相应的金额，可以获得规则之下，金额相应的享受的折扣，需要先定义金额，然后就是使用if语句进行判断，使用switch语句选择判断规则之下对应的优惠折扣。

二、相关代码

public class DiscountPrice 
{
	public static void main(String[] args)
	{
		float money = 3000;//金额
		String rebate = "";//折扣
		if(money > 200)
		{
			int grade = (int) money /200;
					switch (grade)
					{
					case 1: 
					rebate = "九五折";
					break;
					case 2:
						rebate = "九折";
					case 3:
						rebate = "八五折";
					break;
					case 4:
						rebate = "八三折";
					break;
					case 5:
						rebate = "七折";
					break;
					case 6:
						rebate = "七八折";
					break;
					case 7:
						rebate = "七五折";
					break;
					case 8:
						rebate = "七三折";
					break;
					case 9:
						rebate = "七折";
					break;
					case 10:
						rebate = "六五折";
					break;
					default:
						rebate = "六折";
						
					}
		}
		System.out.println("您的累计消费金额为"+money);//输出消费金额
		System.out.println("您将享受"+rebate+"优惠");//输出折扣比例
	}
}
