```java
HttpLoggingInterceptor logging = new HttpLoggingInterceptor();
logging.setLevel(Level.BASIC);
OkHttpClient client = new OkHttpClient.Builder()
  .addInterceptor(logging)
  .build();
```

You can change the log level at any time by calling `setLevel()`.

To log to a custom location, pass a `Logger` instance to the constructor.
```java

        Logger rootLogger = Logger.getLogger("");
        rootLogger.setLevel(Level.ALL);
        ConsoleHandler handler = new ConsoleHandler();
        handler.setFormatter(new SimpleFormatter());
        handler.setLevel(Level.ALL);
        rootLogger.addHandler(handler);
    }

    @Override
    public void tearDown() throws Exception {

  override fun beforeEach(context: ExtensionContext?) {
    previousLevel = logger.level
    logger.addHandler(handler)
    logger.setLevel(Level.FINEST)
  }

  override fun afterEach(context: ExtensionContext?) {
    logger.setLevel(previousLevel)
    logger.removeHandler(handler)
  }

  override fun apply(
    base: Statement,
    description: Description,
  ): Statement =

                LogStream.setLevel(4);
            } else if (logger.isDebugEnabled()) {
                LogStream.setLevel(3);
            } else if (logger.isWarnEnabled()) {
                LogStream.setLevel(2);
            } else if (logger.isErrorEnabled()) {
                LogStream.setLevel(1);
            } else {
                LogStream.setLevel(0);
            }
