정답2 공개 (여기서는 Scanner로 자신이 구매할 자동차 자전거 오토바이를 각각 대수를 입력할수있고 구매할때 색깔 제조사 등은 랜덤으로 정해진다)

package hihihi;

import java.util.Random;

	int a;
	int b;
	int c;
	Human(int a,int b,int c){
		this.a = a;
		this.b = b;
		this.c = c;
		Car[] cr = new Car[a];
		for(int i=0;i<cr.length;i++) {
			cr[i] = new Car();
			System.out.println((i+1) + "번 차 : " + cr[i].color + "," + cr[i].kind + "," + cr[i].speed);
		}
		By[] by = new By[b];
