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.

Example:

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(); } }

Use the first checkbox below to ignore private methods which are called from an anonymous or local class.

Use the third checkbox to only report static methods.
