Editing Java syntax (section)

====Private methods====

Private methods were added in the Java 9 release. An interface can have a method with a body marked as private, in which case it will not be visible to inheriting classes. It can be called from default methods for the purposes of code reuse.

<syntaxhighlight lang="java">
interface Logger {
    default void logError() {
        log(Level.ERROR);
    }

    default void logInfo() {
        log(Level.INFO);
    }

    private void log(Level level) {
        SystemLogger.log(level.id);
    }
}
</syntaxhighlight>
