e401. Limiting the Size of a Log File

By default, a log file can grow without bound. It is possible to limit the size of the file by specifying the desired limit when creating a file handler. When a record is about to be logged and the file size is greater than the limit, the file is emptied before the record is logged. This example creates a file handler with a limit.

    try {
        // Create a file handler with a limit of 1 megabytes
        String pattern = "my.log";
        int limit = 1000000; // 1 Mb
        FileHandler fh = new FileHandler("my.log", limit, 1);
    
        // Add to logger
        Logger logger = Logger.getLogger("com.mycompany");
        logger.addHandler(fh);
    } catch (IOException e) {
    }
