```java
import java.util.*;
class word {
public static void main(String agrs []){
double a,sum = 0;
Scanner sca=new
Scanner(System.in);
System.out.println("请输入用电度数：");
a=sca.nextInt();
if((a>0)&&(a<151)){
sum=0.4463a;
}
else if((a>151)&&(a<401)){
sum=0.4463150+0.4663(a-150);
}
else if(a>401){
sum=0.4463150+0.4663250+0.5663(a-400);
}
}
}
