步骤 操作
1 创建一个展会类 Exhibition，包含展会名称、展会地点等属性
2 创建一个展位类 Booth，包含展位编号、展位位置等属性
3 在主程序中创建一个展会对象和若干个展位对象
4 将展位对象添加到展会对象中
5 实现展会导航功能，可以根据展会名称或展位编号查询展位位置

操作步骤

步骤1：创建展会类 Exhibition

// Exhibition.java
public class Exhibition {
    private String name;
    private String location;
    
    public Exhibition(String name, String location) {
        this.name = name;
        this.location = location;
    }
}

步骤2：创建展位类 Booth

// Booth.java
public class Booth {
    private int number;
    private String position;
    
    public Booth(int number, String position) {
        this.number = number;
        this.position = position;
    }
}

步骤3：创建展会对象和展位对象

// Main.java
public class Main {
    public static void main(String[] args) {
        Exhibition exhibition = new Exhibition("Java Expo", "Convention Center");
        Booth booth1 = new Booth(1, "Hall A");
        Booth booth2 = new Booth(2, "Hall B");
    }
}

步骤4：添加展位到展会对象中

// Main.java
public class Main {
    public static void main(String[] args) {
        Exhibition exhibition = new Exhibition("Java Expo", "Convention Center");
        Booth booth1 = new Booth(1, "Hall A");
        Booth booth2 = new Booth(2, "Hall B");
        
        exhibition.addBooth(booth1);
        exhibition.addBooth(booth2);
    }
}

步骤5：实现展会导航功能

// Exhibition.java
public class Exhibition {
    private List<Booth> booths = new ArrayList<>();
    
    // 添加展位到展会中
    public void addBooth(Booth booth) {
        booths.add(booth);
    }
    
    // 根据展会名称查询展位位置
    public String findBoothByExhibitionName(String name) {
        for (Booth booth : booths) {
            if (booth.getName().equals(name)) {
                return booth.getPosition();
            }
        }
        return "Booth not found";
    }
    
    // 根据展位编号查询展位位置
    public String findBoothByNumber(int number) {
        for (Booth booth : booths) {
            if (booth.getNumber() == number) {
                return booth.getPosition();
            }
        }
        return "Booth not found";
    }
}
