不能直視啊~!~!~!

看了一下自己的代碼,簡(jiǎn)直是,什么鬼~!

package?com.imooc;
import?java.util.Scanner;

public?class?Vehicle?{
	public?int?sum;//總金額?
	public?int?sum2;//總?cè)藬?shù)
	public?int?sum3;//總載貨量
	private?int?days;//總天數(shù)
	public?static?int?price?;//單價(jià)
	public?static?int?burden;//單輛車(chē)載貨量
	public?static?int?seat;//單輛車(chē)載人數(shù)
	public?static?String?name;
	public?static?int[]?burdens?=?{2,4,20};
	public?static?int[]?seats?=?{4,20};
	public?static?String[]?names={"奧迪A4?","馬自達(dá)6","皮卡雪6","金龍?????????????","松花江????????","依維柯???????"};
	public?static?int[]?prices={500,400,450,400,800,1000};
	public?String[]?capacity?=?{"載人:4人","載人:4人","載人:4人載貨:2噸","載人:20人","載貨:4噸","載貨:20噸"};
	Scanner?input?=?new?Scanner(System.in);
	public?void?show(){
		System.out.println("序號(hào)???汽車(chē)類(lèi)型???????租金??????????????????????容量");
		for(int?i=0;i<names.length;i++){
			System.out.println((i+1)+".???"+names[i]+"???"+prices[i]+"元/天???????"+capacity[i]);
		}
		System.out.println("請(qǐng)問(wèn)您要組多少量車(chē)");
	}
	public?void?nums(int?nums){
		for(int?i=1;i<=nums;i++){
			System.out.println("請(qǐng)輸入第"+i+"輛車(chē)序號(hào)");
			int?two?=?input.nextInt();
			if(two<=4?&&two!=3){
				Salooncar.num(two);
				sum?=?sum?+?Salooncar.price;
				sum2?=?sum2?+?Salooncar.seat;
			}else?if(two?==?3){
				Pickup.num(two);
				sum?=?sum?+?Pickup.price;
				sum2?=?sum2?+?Salooncar.seat;
				sum3?=?sum3?+?Wagon.burden;
			}else{
				Wagon.num(two);
				sum?=?sum?+?Wagon.price;
				sum3?=?sum3?+?Wagon.burden;
			}
		}
		System.out.println("請(qǐng)問(wèn)您要租多少天?");
	}
	public?int?getDays()?{
		return?days;
	}
	public?void?setDays(int?days)?{
		this.days?=?days;
	}
	

	public?void?table(){
		System.out.println("***您的賬單***");
		//載人
		System.out.println("***可載人的車(chē)有：");
		
		System.out.println("最多載人數(shù)量:?"+sum2);
		//載貨
		System.out.println("***載貨的車(chē)有：");
		System.out.println("最多載貨數(shù)重量:?"+sum3);

		sum?=?sum*days;
		System.out.println("***租車(chē)總價(jià):"+sum+"元");
	}
}

亂七八糟

package?com.imooc;

public?class?Salooncar?extends?Vehicle?{
	
	
	
	public?static?void?num(int?num){
		switch?(num)?{
		case?1:{
			price?=?prices[num-1];
			seat?=?seats[0];
		}
		break;
		case?2:{
			price?=?prices[num-1];
			seat?=?seats[0];
		}
		break;
		case?4:{
			price?=?prices[num-1];
			seat?=?seats[1];
		}
		break;
		}
	
	}
}

我還是再把第二季再學(xué)一遍好了Orz

package?com.imooc;

public?class?Pickup?extends?Vehicle{
	public?static?void?num(int?num){
		switch?(num)?{
		case?3:{
			price?=?prices[num-1];
			seat?=?seats[0];
			burden?=?burdens[0];
		}
		break;
		}
	}
}

Orz我都不知道自己在寫(xiě)什么了!

package?com.imooc;

public?class?Wagon?extends?Vehicle?{
	
	public?int?lc;
	
	
	public?static?void?num(int?num){
		switch?(num)?{
		case?5:{
			price?=?prices[num-1];
			burden?=?burdens[1];
		}
		break;
		case?6:{
			price?=?prices[num-1];
			burden?=?burdens[2];
		}
		break;
		}
	}

	public?static?void?names(int?lc){
		switch?(lc)?{
		case?5:{
			name?=?names[lc-1];
		}
		break;
		case?6:{
			name?=?names[lc-1];
		}
		break;
		
		}
	}
}

總結(jié):這段代碼簡(jiǎn)直喪心病狂!Orz,早知道就不去看什么參考的內(nèi)容了!搞得我一直在想怎么把參考內(nèi)容弄出來(lái)~!
