Java综合实战：生产者与消费者（问题引出）

假设生产数据如下：

·第一组数据：title=蜡笔小新，cOntent=好学生；

·第二组数据：title=小白，cOntent=好狗狗；

范例：

class Info {
	private String title;
	private String content;

	public void setTitle(String title) {
		this.title = title;
	}

	public String getTitle() {
		return title;
	}

	public void setContent(String content) {
		this.cOntent= content;
	}

	public String getContent() {
		return content;
	}

}

class Productor implements Runnable {// 生产者类
	private Info info;

	public Productor(Info info) {
		this.info = info;
	}

	@Override
	public void run() {
		for (int i = 0; i <10; i++) {
			if (i % 2 == 0) {// 偶数
				this.info.setTitle("蜡笔小新");
				try {
					Thread.sleep(100);
				} catch (Exception e) {
					e.printStackTrace();
				}
				this.info.setContent("好学生");
			} else {
				this.info.setTitle("小白");
				try {
					Thread.sleep(100);
				} catch (Exception e) {
					e.printStackTrace();
				}
				this.info.setContent("好狗狗");
			}
		}
	}
}

class Customer implements Runnable {
	private Info info;

	public Customer(Info info) {
		this.info = info;
	}

	@Override
	public void run() {
		for (int i = 0; i <10; i++) {
			try {
				Thread.sleep(100);
			} catch (Exception e) {
				e.printStackTrace();
			}
			System.out.println(this.info.getTitle() + "->" + this.info.getContent());
		}
	}
}

public class Demo {
	public static void main(String[] args) {
		Info info = new Info();
		new Thread(new Productor(info)).start();
		new Thread(new Customer(info)).start();
	}

}

出现问题：

·数据错位

·数据重复取出
