JAVA 编写完整代码

public class test1 { ?public static void main(String[] args) { ?? Scanner scan = new Scanner(System.in); ?? System.out.println("请输入本月税前工资"); ?? double d = scan.nextDouble(); //税前工资 ?? double sal= d - 3500; // 减去扣除数的 ?? double salary = 0; //初始化工资 ?? if(sal<=1500){ ???? salary = sal*0.03; ?? }else if(sal<=4500){ ??? salary = sal*0.1-105; ?? }else if(sal<=9000){ ??? salary = sal*0.2-555; ?? }else if(sal<=35000){ ??? salary = sal*0.25-1005; ?? }else if(sal<=55000){ ??? salary = sal*0.3-2755; ?? }else if(sal<=80000){ ??? salary = sal*0.35-5505; ?? }else{ ??? salary = sal*0.45-13505; ?? } ?? System.out.println("个人所得税的缴纳额度为："+salary+"元"); ?} } 1. 尽量简化逻辑 像钱的多少 先用变量存储起来 再带入就好了 2. 尽量简化代码? 像输出也只用一句然后带入就好了 3. 尽量自己考虑 每一点问题都是自己敲代码的过程中产生然后明白的 4. 这题是我原题? 我知道你在哪? 既然在那了 为什么还不努力呢
