Java – contrary to C, why can’t you reduce method visibility when overriding?

See English answer > java, cannot reduce the visibility of the inherited method from object

abstract class A {
  protected void method() {}
}

class B extends A {
  private void method() {}
}

public class main{
     public static void main(String []args) {}
}

yes:

main.java:6: error: method() in B cannot override method() in A
  private void method() {}
               ^
  attempting to assign weaker access privileges; was protected
1 error

Set the derived method to protected / private

Question: why does Java not allow you to further restrict access in subclasses? I contrast this with C, which has completely opposite rules

Solution

In Java, all methods are virtual by default (except private and static methods) Therefore, when using java to rewrite a method, it must use the definition in the class referenced by the object With this rule in Java, you can't reduce the visibility of the overridden method, just keep the same visibility or expand it
