Class EventLog

  • All Implemented Interfaces:
    Log

    public class EventLog
extends Object
implements Log
    The EventLog class is an implementation of Log which logs exceptions and messages to the specified file or PrintStream.

    Here is an example use of EventLog, which will write a timestamp and message to the specified file: 

      EventLog myLog = new EventLog("myFile");
  myLog.log("You have successfully written to my log file.");
  myLog.log("Another log message.");

    Each successive message will be appended to the previous messages in the log.

    Here is what the log file will look like:

    Mon Jan 03 09:00:00 CST 2000 Yout have successfully written to my log file.
    Mon Jan 03 09:00:01 CST 2000 Another log message.
