耐心，细心，用心

解题思路:if-else if语句

注意事项:注意差值问题

参考代码:

import java.util.Scanner;

public class Main {

public static void main(String[] args) {

Scanner in = new Scanner(System.in);

int earn = in.nextInt();

int x = 100000;

if(earn<=x) {

System.out.println((int)(earn*0.1));

}

else if(earn>x&&earn<=2*x) {

System.out.println((int)((earn-x)*0.075+x*0.1));

}

else if(earn>2*x&&earn<=4*x) {

System.out.println((int)(x*0.075+x*0.1+(earn-2*x)*0.05));

}

else if(earn>4*x&&earn<=6*x) {

System.out.println((int)(x*0.075+x*0.1+2*x*0.05

+(earn-4*x)*0.03));

}

else if(earn>6*x&&earn<=10*x) {

System.out.println((int)(x*0.075+x*0.1+2*x*0.05

+2*x*0.03+(earn-6*x)*0.015));

}

else if(earn>10*x) {

System.out.println((int)(x*0.075+x*0.1+2*x*0.05

+2*x*0.03+4*x*0.015+(earn-10*x)*0.01));

}

in.close();

}

}
