IT技术System

求java程序大佬运算import java.util.*;

JAVA问题import java.util.*;
public class wen {
public static void main(String[] args) {
int c,s,d=0;
float p,w,f;
Scanner input=new Scanner(System.in);
System.out.print("请输入每公里每吨货物的基本运费（元）: ");

s=input.nextInt();
if(s=3000)
c=12;
else
c=s/250;
switch(c){
case 0:d=0; break;
case 1:d=2; break;
case 2:
case 3:d=5;
case 4:

f=p*w*s*(1-d/100.0f);
System.out.println("你所需付的运费是："+f);

java难题 ， 请求各位高手帮助我解答一下，大家有难题互帮互助？import java.util.Scanner;
interface Traffic{
double calc(double weight,double distance);//计算运费
}
class Trunk implements Traffic{
@Override
public double calc(double weight,double distance) {
return (distance=1000weight=60)?(weight*distance*120):(-1);
}
}
class Train implements Traffic{
@Override
public double calc(double weight, double distance) {
return (distance=900)?(weight*distance*250):(distance*weight*300);
}
}
class Plane implements Traffic{
@Override
public double calc(double weight, double distance) {
return (distance500)?(weight*distance*750):(-1);
}
}
class ZuChe{
private double distance;//距离
private double weight;//重量
public String useTraffic(Traffic t){
double result = t.calc(weight, distance);
return (result!=-1)?(""+result):(t.getClass().getName().equals(Trunk.class.getName())?"超重或者距离太远不能接单":"拒载");
