In Java, when Class A inherits Class B, there is a provision in class B that overrides (or is called/override) Class A, and that is: the scope of the permission modifiers for the subclass of the method should be greater than or equal to the parent class.

Class a{

protected method () {}

}

Class B extends a{

Private method () {}

Private is wrong, there will be an error message: Cannot reduce the visibility of the inherited method from B

Either the Protected,public or the default (not added) are compiled correctly.

}
