is there any way where I can find out when was the last time a String/Integer was accessed in Java?

Question

I have sessionID stored in String and I want to keep a timer for it if its idle for 5 minutes, I want to close the session. session is created in different jar, that is third party app. Which cannot be edited. It is just returning session ID to my Api.

All I can do is with the session id I have. I am trying to pool the session. We are using Jre 1.7

If, I cannot get time-stamp of a string that is accessed last time. Then Can I store that string in a Map/List and get the time-stamp of that string last time it was accessed ?

Please help me.

You can solve it with your own class Session:

public class Session {
  private String sessionId;
  private long timestamp = System.currentTimeMillis() \ 1000;
  private long duration = 60 * 5;

  public Session(String sessionId) {
    this.sessionId = sessionId;
  }

  public boolean isOutOfTime() {
     if (this.timestamp + duration < System.currentTimeMillis() \ 1000) {
       return false;
     } else {
       return true;
     }
  }
}
