一、题目

二、实验代码

public class DangerException extends Exception {
	private String message;
	

	public String getMessage() {
		return message;
	}

	public void setMessage(String message) {
		this.message = message;
	}

	public DangerException(String m) {
		message = m + "为危险物品!";
	}

	public void toShow() {
		System.out.println(message);
	}
}

public class Goods {
	private boolean isDanger;
	private String name;

	public void setisDanger(boolean isDanger) {
		this.isDanger = isDanger;
	}

	public String getName() {
		return name;
	}

	public void setName(String name) {
		this.name = name;
	}

	public boolean isDanger() {
		return isDanger;
	}
}

public class Machine {
	public void CheckBag(Goods goods) throws DangerException {
		if (goods.isDanger()) {
			throw new DangerException(goods.getName());
		} else {
			System.out.println(goods.getName() + "为非危险物品检查通过");
		}
	}
}

import java.util.Scanner;

public class Test {

	public static void main(String[] args) {
		Machine m = new Machine();
		Goods goods = new Goods();
		Scanner scanner = new Scanner(System.in);
		for (int i = 0; i < 10; i++) {
			String name = scanner.next();
			goods.setName(name);
			if (goods.getName().equals("毒品") || goods.getName().equals("刀具") || goods.getName().equals("汽油")
					|| goods.getName().equals("枪")) {
				goods.setisDanger(true);
			} else {
				goods.setisDanger(false);
			}
			try {
				m.CheckBag(goods);
			} catch (DangerException e) {
				e.toShow();
			}
		}
	}
}
