我试图通过反射获取静态私有属性的值,但它失败并出现错误.

Class class = home.Student.class;
Field field = studentClass.getDeclaredField("nstance");
Object obj = field.get(null);

我得到的例外是:

java.lang.IllegalAccessException: Class com.test.ReflectionTest can not access a member of class home.Student with modifiers "private static".

此外,我需要使用以下代码调用私有.

Method method = studentClass.getMethod("addMarks");
method.invoke(studentClass.newInstance(), 1);

但问题是Student类是单例类,而构造函数是私有的,无法访问.
