How do I limit the size of log file?

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;

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);
        } catch (IOException e) {
            logger.warning("Failed to initialize logger handler.");
        }"Test info");
        logger.warning("Test warning");
        logger.severe("Test severe");
