JavaSE进阶
（7）NoteBook、PC、Printer类
观察显示格式：
- NoteBook显示的是型号（价格）
- PC显示的是型号（显示器）
- Printer显示的是名称（类型）

package com.atguigu.bean; public class NoteBook implements Equipment{ private String model;//型号 private double price;//价格 public NoteBook() { super(); } public NoteBook(String model, double price) { super(); this.model = model; this.price = price; } public String getModel() { return model; } public void setModel(String model) { this.model = model; } public double getPrice() { return price; } public void setPrice(double price) { this.price = price; } @Override public String getDescription() { return model+"("+price+")"; } @Override public String toString() { return getDescription(); } } |
