范例

class Info {
	private String title;
	private String content;

	public synchronized void set(String title, String content) {
		this.title = title;
		try {
			Thread.sleep(200);
		} catch (Exception e) {
			e.printStackTrace();
		}
		this.content = content;
	}

	public synchronized void get() {
		try {
			Thread.sleep(20);
		} catch (Exception e) {
			e.printStackTrace();
		}
		System.out.println(this.title + "->" + this.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) {
				this.info.set("蜡笔小新", "好学生");
			} else {
				this.info.set("小白", "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 < 20; i++) {
			this.info.get();
		}
	}
}

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();
	}

}

错位问题解决了,但是重复数据更加严重了
