在 Java 中，是否可以使用超级关键字从子 ZA2F2ED4F8EBC2CBB4C21A2 引用父 class 的 static 变量？

Question

Whether it is possible to refer static variable of parent class from child class using super keyword?

Answer 1

Yes, you can use the super.fieldName . It will compile and run as it should. But it is not necessary to use super.fieldName or ParentClassName.fieldName to access static members of the Superclass from the Subclass. It can be accessed directly with the fieldName .

class Parent {
  static int a = 10;
}

class Child extends Parent {
  public void print() {
    System.out.println(super.a); //valid
    System.out.println(Parent.a); //valid
    System.out.println(a); //valid
  }
}
