重构后

class InheritanceDelegation {

    public static void main(String[] args) {
        InnerClass innerClass = new InnerClass();
        print(innerClass);
    }

    private static void print(InnerClass innerClass) {
        innerClass.print();
    }

    private static class InnerClass {
        private final MyAbstractClass abstractClass = new MyAbstractClass();

        public AbstractClass getAbstractClass() {
            return abstractClass;
        }

        public void print() {
            abstractClass.print();
        }

        public void evaluate() {
            abstractClass.evaluate();
        }

        private class MyAbstractClass extends AbstractClass {
            public void evaluate() {
            }
        }
    }

    private abstract static class AbstractClass {
