    新手写码,不规范请见谅
    double b = -1;
    Scanner input=new Scanner(System.in);
    System.out.println("请输入薪水:");
    double a=input.nextInt();

    if(a>0&&a<=3500){
        b=0;
    }else if(a>3500&&a<=5000){
        b=(a-3500)*0.03;
    }else if(a>5000&&a<=8000){
        b=1500*0.03+(a-5000)*0.1;
    }else if(a>8000){
        b=1500*0.03+3000*0.1+(a-8000)*0.2;
    }

    if(b==0){
        System.out.println("不交税");
