Private method only used from inner class

Reports private methods which are only called from an inner class of the class containing the method. Such methods can be safely moved into that inner class.


public class Outer { public static void main(String[] args) { new Inner().run(args[0]); } static class Inner { void run(String arg) { // Method isEmpty() is used from Inner class only // consider moving it to the Inner class if (!isEmpty(arg)) { System.out.println("Argument is supplied"); } } } private static boolean isEmpty(String s) { return s != null && s.trim().isEmpty(); } }

Locating this inspection


Can be used to locate inspection in e.g. Qodana configuration files, where you can quickly enable or disable it, or adjust its settings.

Via Settings dialog

Path to the inspection settings via IntelliJ Platform IDE Settings dialog, when you need to adjust inspection settings directly from your IDE.
