继承的两个抽象类里面的两个抽象方法如下：

public abstract class Capacity{
public abstract int passengerCapacity(int e[], int d);
public abstract int carryingCapacity(int s[], int b);
}

主类调用并实现功能：

import java.util.Scanner;
public class Text extends Capacity{
    @Override
    public int passengerCapacity(int e[], int d){
        int humannumber=0;
        int money=0;
        int eeeee = 0,ee = 0, eee = 0, eeee= 0;
        for(int j = 0; j<d;j++){
            if(e[j] == 1){
                eeeee = eeeee+1;
                System.out.print("奥迪A4: "+ eeeee+"辆 ");
                humannumber = humannumber+4;
                money = money+500;
            }
            else if(e[j] == 2){
