public class TestDeclaredMethod {
    public static void main(String[] args) throws Exception {
        Class clazz = Class.forName("com.leetcode.B");
        B b = (B) clazz.newInstance();
        Method method = clazz.getDeclaredMethod("println");
        method.invoke(b);
    }
}
class B extends A {
    @Override
    public void println() {
        System.out.println("B");
    }
}
class A {
    public void println() {
        System.out.println("A");
    }
}

老师，你好，关于getDeclaredMethod()这个方法上面代码测试是可以获取继承方法的啊，请问是我哪写的不对么？谢谢！
