In this example you learn how to limit the size of a log file when using a FileHandler
handler. Limiting the log file will prevent the log file to grow wildly without limit.
package org.kodejava.util.logging;
import java.util.logging.Logger;
import java.util.logging.FileHandler;
import java.io.IOException;
public class LogFileLimit {
// The log file size is set to 1 MB.
public static final int FILE_SIZE = 1024 * 1024;
public static void main(String[] args) {
Logger logger = Logger.getLogger(LogFileLimit.class.getName());
try {
// Create a FileHandler with 1 MB file size and a single log file.
// We also tell the handler to append the log message.
FileHandler handler = new FileHandler("myapp.log", FILE_SIZE, 1, true);
logger.addHandler(handler);
} catch (IOException e) {
logger.warning("Failed to initialize logger handler.");
}
logger.info("Test info");
logger.warning("Test warning");
logger.severe("Test severe");
}
}
