用java编写个人所得税，超过1600元要纳税

public static void main(String[] args) {

System.out.println("输入你的收入：");

Scanner input = new Scanner(System.in);

double money = input.nextFloat();

double tax = 0;

if(money = 500){

tax = money * 0.05;

}else if(money  500  money = 20000){

tax = money * 0.1;

}

// .....

System.out.println("纳税：" + tax + " 元");

}

在MyEclipse环境下用java怎样编写一个计算中国个人所得税的程序

public float ComputeTax(float income) //income为工资

{

float f_income=income-800; //起征基数为800，同时也可以参数化处理

float[] tax_line={0f,500f,2000f,5000f,20000f,40000f,60000f,80000f,100000f};//计算个人所得税的档次（假设员工为中国国籍，因为国籍不同起征点数不同，税率不同。）

float[] tax_rate={0f,0.05f,0.10f,0.15f,0.20f,0.25f,0.30f,0.35f,0.40f}; //各档次税率

float[] tax_sub={0.f,25f,125f,375f,1375f,3375f,6375f,10375f,15375f}; //采用了简化算法

int i_tax_level=0; //为了计算简便，把工资进行分档

while(f_incometax_line[i_tax_level]i_tax_leveltax_line.length)

{

i_tax_level++;

};

if(i_tax_level0)

{

float f_tax=tax_sub[i_tax_level-1]+(f_income-tax_line[i_tax_level-1])*tax_rate[i_tax_level]; //算税的公式

return f_tax;

}

else

{

return 0f;

}

}
