如何使皮卡既显示载人又显示载客

if(is==1){
   for(Didi currentCar:carsForRent){
    if(currentCar instanceof PassengerCar){
     System.out.println(""+i+"\t"+currentCar.getName()+"\t"+currentCar.getRentm()+"元/天"+"\t"+currentCar.getTake()+"人");
    i++;
    }
    else{
     System.out.println(""+i+"\t"+currentCar.getName()+"\t"+currentCar.getRentm()+"元/天"+"\t"+currentCar.getTon()+"吨");
    i++;
    }
   }
  } 做到这一步程序没问题就是不知道如何让皮卡那一栏既显示载人又显示载客

    if(xz==1){
           System.out.println("您可租车的类型及其价目表"+"\n"+"序号"+"\t"+"汽车名称"+"\t"+"租金"+"\t"+"容量");
           for(int i=0;i<6;i++){
               if(car[i].dun==0){
           System.out.println((i+1)+".\t"+car[i].name+"\t"+car[i].price+"元/天"+"\t"+car[i].person+"人");
           }else if(car[i].person==0){
               System.out.println((i+1)+".\t"+car[i].name+"\t"+car[i].price+"元/天"+"\t"+"载货："+car[i].dun+"吨");
           }else{
               System.out.println((i+1)+".\t"+car[i].name+"\t"+car[i].price+"元/天"+"\t"+car[i].person+"人"+"载货："+car[i].dun+"吨");
           }
           }
       }else{
           return;
       }

这样判断就可以

我已经解决了

if(is==1){

for(Didi currentCar:carsForRent){

if(currentCar instanceof PassengerCar){

System.out.println(""+i+"\t"+currentCar.getName()+"\t"+currentCar.getRentm()+"元/天"+"\t"+"载人:"+currentCar.getTake()+"人");

i++;

}

else if(currentCar instanceof PickUp){

System.out.println(""+i+"\t"+currentCar.getName()+"\t"+currentCar.getRentm()+"元/天"+"\t"+"载人:"+currentCar.getTake()+"人"+"载货:"+currentCar.getTon()+"吨");

i++;

}else{

System.out.println(""+i+"\t"+currentCar.getName()+"\t"+currentCar.getRentm()+"元/天"+"\t"+"载货:"+currentCar.getTon()+"吨");

i++;

}
