对象数组简单实现

class Book {
	private String title;
	private double price;

	public Book() {
	}
	public Book(String t, double p) {
		title = t;
		price = p;
	}

	public void setTitle(String t) {
		title = t;
	}
	public void setPrice(double p) {
		if (p < 0){
			return;
		}
	}
	public String getTitle() {
		return title;
	}
	public double getPrice() {
		return price;
	}

	public String getInfo() {
		return "书名： " + title + " 价格：" + price;
	}
}

public class ArrayDemo {
	public static void main(String args[]) {
		Book bk [] = new Book [] {
			new Book("语文", 10.1),
			new Book("数学", 10.2),
			new Book("英语", 10.3),
		};
			for (int x = 0; x < bk.length; x++) {
				System.out.println(bk[x].getInfo());
			}
	}
}

记录当初初学的过程，有些结构没有体现Java完整语法。
