本文介绍了一个简单实用的日志记录器类实现。该类能够根据消息及其时间戳判断是否应该打印这条消息，确保相同消息不会在10秒内被重复打印。

 1 public class Logger {
 2     private Map<String, Integer> data;
 3     /** Initialize your data structure here. */
 4     public Logger() {
 5         data = new HashMap<>();
 6     }
 7     
 8     /** Returns true if the message should be printed in the given timestamp, otherwise returns false.
 9         If this method returns false, the message will not be printed.
10         The timestamp is in seconds granularity. */
11     public boolean shouldPrintMessage(int timestamp, String message) {
12         if (!data.containsKey(message) || timestamp - data.get(message) >= 10) {
13             data.put(message, timestamp);
14             return true;
15         }
16         return false;
17     }
18 }
19 
20 /**
21  * Your Logger object will be instantiated and called as such:
22  * Logger obj = new Logger();
23  * boolean param_1 = obj.shouldPrintMessage(timestamp,message);
24  */
