纳税

题目：
       在美国，不同的税率是根据纳税人的婚姻状况而定的。单身和已婚的纳税人有不同的税收计划。已婚的纳税人将他们的收入加在一起，并支付总的税。如下表计算税率。不同税率适合于每一个“分支”。在表中，第一个分支的收入为10%，第二个分支的收入为25%。每个分支的收入范围取决于婚姻状况。

代码：

import java.util.Scanner;
public class taxRate 
{
	
	private static Scanner in;

	public static void main(String[] args)
	{
		final double rate1 = 0.10;
		final double rate2 = 0.25;
		final double singleLimit = 32000;
		final double marriedLimit = 64000;
		double tax1 = 0;
		double tax2 = 0;
		in = new Scanner(System.in);
		System.out.print("please input your income:");
		double income = in.nextDouble();
		System.out.print("please input s for single or m for married:");
		String maritalStatue = in.next();
		if(maritalStatue.equals("s"))
		{
			if(income<=singleLimit)
			{
				tax1 = rate1 * income;
			}
			else
			{
				tax1 = rate1 * singleLimit;
				tax2 = rate2 * (income - singleLimit);
			}
		}
		else
		{
			if(income<=marriedLimit)
			{
				tax1 = rate1 * income;
			}
			else
			{
				tax1 = rate1 * marriedLimit;
				tax2 = rate2 * (income - marriedLimit);
			}
		}
		double totalTax = tax1 + tax2;
		System.out.println("The tax is $"+totalTax);
	}
	
}
