In Java, you can print logs using the following methods:

  1. Print logs using the System.out.println() method.
  2. Println(“Log content”);
  3. Print logs using the Java.util.logging.Logger class.
  4. Create a Logger object using the Java Util Logging package, set it to the name of your class, and then log the message “日志内容” at the info level.
  5. Use the Log4j library to print logs.
  6. Logger logger = Logger.getLogger(YourClass.class);

    logger.info(“Log message”);

  7. Print logs using SLF4J (Simple Logging Facade for Java).
  8. Create a Logger object using the LoggerFactory class from the org.slf4j package, assign it to a variable named logger, and then log the message “日志内容” at the info level.

The above are some common ways of logging in your projects, the specific method to use depends on your project requirements and choice of logging framework.
