Java 9에서는 인터페이스에 개인 메소드 또는 개인 정적 메소드를 정의할 수 있습니까?

interface  { private static void methodName() { // some statements } private void methodName() { // some statements } }

interface Java9Interface { public abstract void method1(); public default void method2() { method4(); method5(); System.out.println("Inside default method"); } public static void method3() { method5(); // static method inside other static method System.out.println("Inside static method"); } private void method4() { // private method System.out.println("Inside private method"); } private static void method5() { // private static method System.out.println("Inside private static method"); } } public class PrivateStaticMethodTest implements Java9Interface { @Override public void method1() { System.out.println("Inside abstract method"); } public static void main(String args[]) { Java9Interface instance = new PrivateStaticMethodTest(); instance.method1(); instance.method2(); Java9Interface.method3(); } }

Inside abstract method Inside private method Inside private static method Inside default method Inside private static method Inside static method
