Java で内部クラスから外部クラスにアクセスするにはどうすればよいですか?

public class OuterClass {

    public class InnerClass {
        private String name = "Peakit";
        
        public OuterClass outer() {
            return OuterClass.this;
        }
    }

    public static void main(String[] args) {
        OuterClass outer = new OuterClass();
        InnerClass inner = outer.new InnerClass();
        
        OuterClass anotherOuter = inner.outer();

        if(anotherOuter == outer) {
             System.out.println("Was able to reach out to the outer object via inner !!");
        } else {
             System.out.println("No luck :-( ");
        }
    }
}

Field field = InnerClass.class.getDeclaredField("this");
field.setAccessible(true);
OuterClass outer = (OuterClass) field.get(inner);
